JANUARY WEATHER IN SAN DIEGO

JANUARY IS USUALLY THE COLDEST MONTH OF THE YEAR IN SAN DIEGO AND
THE ONLY MONTH WHEN TEMPERATURES BELOW THE FREEZING POINT WERE
EXPERIENCED AT THE NATIONAL WEATHER SERVICE.  ONLY ON 9 DAYS HAS
A READING OF 32 DEGREES OR BELOW BEEN RECORDED SINCE RECORDS
BEGAN IN 1872 WITH THE ABSOLUTE LOW OF 25 DEGREES ON JANUARY 7,
1913.  THE AVERAGE MINIMUM TEMPERATURE FOR THE MONTH IS 49.7

WITH AN AVERAGE OF 7 DAYS WITH RAIN IT IS THE WETTEST MONTH OF
THE YEAR.  THE NORMAL TOTAL IS 2.28 INCHES BUT AMOUNTS VARY
WIDELY FROM YEAR TO YEAR RANGING FROM 8.06 INCHES IN 1995 TO NO
RAIN IN SEVERAL JANUARYS.  SMALL HAIL HAS OCCURRED OCCASIONALLY.
A FEW SNOWFLAKES WERE OBSERVED MELTING AS SOON AS THEY REACHED
THE GROUND ON JANUARY 10, 1949 THE ONLY DAY IN JANUARY SNOW HAS

STRONG WINDS SOMETIMES ACCOMPANIED THE RAINS REACHING VELOCITIES
OF 30 TO 35 MPH AND GUSTS BETWEEN 40 TO 45 MPH.  THE FASTEST WIND
IN ANY JANUARY WAS OF 64 MPH IN 1988.

THE SUN SHINES 72 PERCENT OF THE TIME POSSIBLE AND THE AVERAGE
MONTH HAS 12 CLEAR, 8 PARTLY CLOUDY AND 11 CLOUDY DAYS.  HEAVY
FOG OVERSPREAD THE CITY ON AN AVERAGE OF 3 DAYS EACH JANUARY BUT
IT IS A MOST VARIABLE PHENOMENON, SOME MONTHS HAVING AS HIGH AS
10 DAYS.  THE RELATIVE HUMIDITY IS QUITE LOW AVERAGING 70 PERCENT
IN EARLY MORNING, 55 PERCENT NEAR NOON AND 55 PERCENT IN LATE
AFTERNOON.



                 FEBRUARY WEATHER IN SAN DIEGO

LONGER DAYS IN FEBRUARY PRODUCE A SLIGHT RISE IN TEMPERATURE OVER
THE PREVIOUS MONTH.  THE MONTHLY MEAN OF 59.0 DEGREES IS 1.2
DEGREES HIGHER THAN THAT OF JANUARY.  THE AVERAGE DAILY MINIMUM
IS 51.5 DEGREES AND THE AVERAGE DAILY MAXIMUM IS 66.3 DEGREES.
IN MOST FEBRUARYS THE MAXIMUM REACHES 70 DEGREES OR EVEN 80
DEGREES AND ONCE IN 1921 IT SOARED TO 89 DEGREES.  A FREEZING
TEMPERATURE HAS NEVER BEEN REGISTERED DURING THE MONTH AT THE
NATIONAL WEATHER SERVICE.  THE LOWEST READING WAS 34 DEGREES IN
1891...1894...1899 AND 1911.

THE MEAN RAINFALL FOR FEBRUARY IS NORMALLY 2.04 INCHES.  THE
AVERAGE NUMBER OF RAINY DAYS IS 6 BUT IN 1884 A MEASURABLE AMOUNT

1912 AND 1967 WERE WITHOUT ANY RAIN.  SMALL HAIL HAS OCCURRED AT
INTERVALS BUT NO SNOW HAS BEEN OBSERVED DURING THE MONTH.

AS IN OTHER WINTER MONTHS...WINDS REACHING 30 MPH OR STRONGER
OCCASIONALLY HAVE OCCURRED IN RAIN STORMS WITH THE MAXIMUM OF 53
MPH IN 1938.

THE RELATIVE HUMIDITY CONTINUES MODERATELY LOW AVERAGING 72
PERCENT IN THE EARLY MORNING...58 PERCENT NEAR NOON AND 58 PERCENT
IN THE LATE AFTERNOON.  SUNSHINE AVERAGES 73 PERCENT OF POSSIBLE
WITH 11 CLEAR...7 PARTLY CLOUDY AND 10 CLOUDY DAYS.  HEAVY FOG
FORMS ON AN AVERAGE OF 3 DAYS BUT THERE IS WIDE VARIATION FROM
YEAR TO YEAR.

                MARCH WEATHER IN SAN DIEGO

TEMPERATURES CONTINUE TO CLIMB IN MARCH AND THE MONTHLY MEAN OF
60.0 DEGREES IS 1.1 DEGREE HIGHER THAN THAT OF FEBRUARY AND 2.2
DEGREES HIGHER THAN THAT OF JANUARY.  THE AVERAGE DAILY MAXIMUM
IS 66.3 DEGREES AND THE AVERAGE DAILY MINIMUM OF 53.6 DEGREES.
THE ABSOLUTE LOW OF 36 DEGREES WAS RECORDED IN 1894 AND THE
ABSOLUTE HIGH OF 99 DEGREES WAS RECORDED IN 1879.  OCCASIONALLY
HOT DRY WINDS FROM THE INTERIOR HAVE CAUSED TEMPERATURES TO RISE
WELL INTO THE 80S AND ON FOUR DAYS INTO THE 90S. THE LAST TIME
A MAXIMUM TEMPERATURE OF 90 DEGREES OR ABOVE OCCURRED WAS ON THE
29TH OF 2005, WHEN THE TEMPERATURE SOARED TO 91 DEGREES.

STILL IN THE RAINY SEASON, MARCH IS NORMALLY THE SECOND WETTEST
MONTH AVERAGING 2.26 INCHES AND 7 DAYS WITH MEASURABLE AMOUNTS.
IN 6 OF THE MONTHS THE TOTAL PRECIPITATION HAS EXCEEDED 5 INCHES
BUT ON THE OTHER HAND IN 1857 AND 1865 NONE WAS RECORDED.  THE
GREATEST RAINFALL IN ANY ONE MARCH WAS 7.88 INCHES IN 1867.

AS IN THE TWO PREVIOUS MONTHS STORMY WEATHER AND HIGH WINDS HAVE
BEEN FREQUENT AND IN 1938 A MAXIMUM VELOCITY OF 51 MPH WAS
RECORDED AT THE NATIONAL WEATHER SERVICE.

THERE ARE 11 CLEAR, 9 PARTLY CLOUDY AND 11 CLOUDY DAYS ON AVERAGE
AND 2 DAYS WITH HEAVY FOG. SUNSHINE IS 70 PERCENT OF THE
POSSIBLE AND RELATIVE HUMIDITY IS ABOUT THE SAME AS IN JANUARY
AND FEBRUARY WITH AN AVERAGE OF 74 PERCENT IN THE EARLY MORNING,
60 PERCENT NEAR NOON AND 59 PERCENT IN THE LATE AFTERNOON.

                 APRIL WEATHER IN SAN DIEGO

TEMPERATURES CONTINUE TO RISE SLOWLY THROUGH APRIL AND THE MONTHLY
MEAN OF 62.6 DEGREES IS 2.6 DEGREES ABOVE THAT OF MARCH.  THE
AVERAGE DAILY MAXIMUM IS 68.7 DEGREES AND THE AVERAGE DAILY
MINIMUM IS 56.4 DEGREES.  IN SOME APRILS THERE HAVE BEEN DAYS
WITH HOT, DRY WINDS AND TEMPERATURES WELL IN EXCESS OF 80
DEGREES.  ON 11 SUCH OCCURRENCES, 90 DEGREES OR HIGHER HAS BEEN
RECORDED AT THE NATIONAL WEATHER SERVICE.  THE EXTREMES FOR THE
MONTH ARE 98 DEGREES IN 1989 AND 39 DEGREES IN 1875.

SHOWERS RATHER THAN PROLONGED RAINS HAVE BEEN THE RULE. THESE
HAVE OCCURRED ON AN AVERAGE OF 5 DAYS DURING THE MONTH. NORMAL
RAINFALL FOR THE MONTH IS 0.75 INCH HOWEVER IN 1926 THE EXCEPTIONALLY
LARGE TOTAL OF 5.37 INCHES WAS RECORDED OF WHICH 3.23 INCHES FELL
IN ONE DAY. THIS IS ONE OF THE HEAVIEST 24 HOUR RAINFALL AMOUNTS
EVER MEASURED IN THE CITY. ONLY THREE TIMES SINCE 1850 HAS THE
MONTH BEEN WITHOUT MEASURABLE RAINFALL.

STRONG WINDS HAVE BEEN OF SHORT DURATIONS AND RARELY OVER 30 MPH,
BUT ONCE IN 1915 A VELOCITY OF 46 MPH WAS REGISTERED AT THE
NATIONAL WEATHER SERVICE.

AS A RULE APRIL USHERS IN THE NIGHT AND EARLY MORNING LOW CLOUDS
SO CHARACTERISTIC OF OUR SUMMER AND FALL MONTHS, BUT THE
PERCENTAGE OF SUNSHINE IS LITTLE AFFECTED BY THE CLOUDINESS AND
THE AVERAGE OF 66 PERCENT OF POSSIBLE SUNSHINE IS ONLY SLIGHTLY
BELOW THAT OF THE PRECEDING MONTHS.  CLEAR DAYS AVERAGE 10,
PARTLY CLOUDY 10 AND CLOUDY 10.  THERE IS AN AVERAGE OF 1 DAY OF
HEAVY FOG.  THE RELATIVE HUMIDITY AVERAGES 76 PERCENT IN THE
EARLY MORNING, 60 PERCENT NEAR NOON AND 59 PERCENT IN THE LATE
AFTERNOON.

                 MAY WEATHER IN SAN DIEGO

MAY IS NORMALLY CHARACTERIZED BY PERSISTENT OVERCAST SKIES DURING
THE NIGHT AND MORNING HOURS AND BY LESS SUNSHINE THAN ANY OTHER
MONTH EXCEPT JUNE.  TEMPERATURES CONTINUE THEIR UPWARD TREND WITH
THE MOST NOTICEABLE RISE IN NIGHTTIME READINGS.  THE NORMAL DAILY
MAXIMUM FOR THE MONTH IS 69.3 DEGREES...THE NORMAL DAILY MINIMUM
59.8 DEGREES AND THE MEAN 64.6 DEGREES.  ON TEN DAYS THE RECORD
MAXIMUM TEMPERATURES ARE IN THE 90S AND WAS 98 DEGREES ON MAY 25...
1896 THE ABSOLUTE HIGH FOR MAY.  HOWEVER...THE COOL SEA BREEZE
PREVAILS NEARLY EVERY DAY AND TEMPERATURES ABOVE 80 DEGREES
RARELY HAVE BEEN REACHED.  NIGHTS ARE UNIFORMLY MILD AND THE
LOWEST READING DURING THE MONTH WAS 45 DEGREES IN 1915.

OUR LONG DRY SEASON USUALLY BEGINS IN MAY AND THE AVERAGE NUMBER
OF DAYS WITH MEASURABLE RAIN IS 2 WITH AN AVERAGE MONTHLY TOTAL OF
0.20 INCH.  HOWEVER...ON 3 OCCASIONS THE MONTHLY TOTAL HAS EXCEEDED
2 INCHES WITH THE GREATEST RAINFALL 2.54 INCHES IN 1921.

STORMY WEATHER IS ALMOST UNKNOWN DURING THE MONTH AND WINDS OVER
20 MPH HAVE BEEN INFREQUENT.  ONLY TWICE HAVE WINDS OVER 30 MPH
BEEN RECORDED AT THE NATIONAL WEATHER SERVICE OFFICE.  THE HIGHEST
WIND EVER RECORDED IN MAY WAS 40 MPH ON MAY 29...1988.  THE OTHER
TIME WINDS OVER 30 MPH WERE RECORDED WAS IN 1922 WHEN WINDS OF
37 MPH WERE REGISTERED

ALTHOUGH SKIES ARE COMMONLY OVERCAST DURING THE NIGHT AND MORNING
HOURS...HEAVY FOG IS RARE...THE AVERAGE BEING ONLY 1 EACH MAY.
CLEAR DAYS NUMBER 8...PARTLY CLOUDY 12 AND CLOUDY 11. POSSIBLE SUN
SHINE IS 58 PERCENT ON ANY GIVEN DAY...ABOUT 11 PERCENT LESS
THAN THE WINTER DAYS AVERAGE.  MAY AND JUNE ARE THE CLOUDIEST MONTHS
OF THE YEAR WHICH IS A PARADOX BECAUSE THEY ARE TWO OF THE 5
DRIEST MONTHS OF THE YEAR.  RELATIVE HUMIDITY SHOWS LITTLE CHANGE
FROM APRIL WITH HUMIDITY IN THE EARLY MORNING 77 PERCENT...NEAR
NOON 65 PERCENT AND IN THE AFTERNOON 64 PERCENT.

                 JUNE WEATHER IN SAN DIEGO

TEMPERATURE IN JUNE CONTINUES THE SLOW RISE OF PRECEDING MONTHS
AND THE MEAN OF 67.4 IS 2.8 DEGREES ABOVE THE MEAN FOR MAY.  THE
DAILY MAXIMUM AVERAGES 72.2 DEGREES AND THE DAILY MINIMUM 62.6
DEGREES.  CHANGES FROM DAY TO DAY NORMALLY HAVE BEEN SMALL AND
12 DAYS SINCE 1872 HAVE HAD A MAXIMUM 90 DEGREES OR
HIGHER.  THE ABSOLUTE HIGH IS 101 DEGREES IN 1979.  THE ABSOLUTE
LOW IS 50 DEGREES WHICH LAST OCCURRED IN 1943.

WELL INTO THE DRY SEASON, JUNE AVERAGES ONLY ONE DAY WITH
MEASURABLE RAIN AND A MONTHLY AVERAGE OF 0.09 INCH.  ONLY TWICE
SINCE 1850 HAS THE MONTHLY TOTAL EXCEEDED ONE HALF INCH.  THIS
WAS IN 1850 WITH 0.68 INCH AND 1990 WITH 0.87 INCH.

JUNE IS A QUIET MONTH AT SAN DIEGO-LINDBERGH FIELD. STRONG WINDS HAVE
NOT BEEN MEASURED AND THE HIGHEST VELOCITY EVER RECORDED AT THE
AIRPORT WEATHER SERVICE OFFICE WAS 27 MPH. THUNDERSTORMS WILL
OCCASIONALLY DEVELOP IN THE MOUNTAINS AND DESERTS WITH MONSOONAL
MOISTURE.

JUNE IS NORMALLY THE CLOUDIEST MONTH OF THE YEAR WITH ONLY 57
PERCENT OF POSSIBLE SUNSHINE DUE LARGELY TO THE PERSISTENCE OF
OVERCAST SKIES DURING THE MORNING HOURS.  CLEAR DAYS AVERAGE 9,
PARTLY CLOUDY 12 AND CLOUDY 9.  THERE IS AN AVERAGE OF 1 DAY OF
HEAVY FOG.  RELATIVE HUMIDITIES SHOW A SLIGHT INCREASE OVER
PREVIOUS MONTHS WITH AVERAGES OF 81 PERCENT NEAR SUNRISE, 69
PERCENT NEAR NOON AND 66 PERCENT NEAR 4 PM.


                 JULY WEATHER IN SAN DIEGO

NIGHT AND MORNING CLOUDINESS CONTINUES THROUGH JULY...BUT
AFTERNOONS ARE GENERALLY CLEAR AND BRIGHT.  UNDER THE PROTECTIVE
BLANKET OF MOIST AIR FROM THE PACIFIC, TEMPERATURES ARE LOW FOR
THE LATITUDE.  THE DAILY MAXIMUM TEMPERATURE RARELY EXCEEDS 85
DEGREES.  THE HIGHEST TEMPERATURE IN JULY WAS 100 DEGREES IN 1930
AND THE LOWEST TEMPERATURE WAS 54 DEGREES IN 1884.  THE AVERAGE
DAILY MAXIMUM TEMPERATURE IS 75.8 DEGREES...THE DAILY MINIMUM 65.9
DEGREES AND THE MONTHLY MEAN 70.9 DEGREES.  HOT...HUMID WEATHER IS
ALMOST UNKNOWN AND AS A RESULT THUNDERSTORMS RARELY OCCUR...BUT
JULY BEGINS THE THUNDERSTORM SEASON IN THE MOUNTAINS AND DESERTS.

THE MONTH IS IN THE HEART OF THE DRY SEASON AND RAINFALL IS
NEGLIGIBLE AVERAGING ONLY 0.03 INCH.  SINCE THE RECORD BEGAN IN
1850 OVER HALF OF THE JULYS HAVE BEEN WITHOUT MEASURABLE
RAINFALL.  THE WETTEST AND THE ONLY ONE WITH A TOTAL OF OVER AN
INCH WAS 1865 WITH 1.29 INCHES.

AS THERE HAVE BEEN NO STORMS OF ANY INTENSITY DURING JULY...WINDS
HAVE NEVER BEEN STRONG AND THE HIGHEST VELOCITY RECORDED AT THE
NATIONAL WEATHER SERVICE WAS ONLY 30 MPH IN 1925.

THE AVERAGE SUNSHINE IS 68 PERCENT OF THE POSSIBLE OR ABOUT 12
PERCENT ABOVE THE AMOUNT FOR JUNE.  HEAVY FOG HAS AVERAGED ABOUT
ONCE EACH JULY AND NORMALLY THERE ARE 13 CLEAR...13 PARTLY CLOUDY
AND 5 CLOUDY DAYS.  THE RELATIVE HUMIDITY AVERAGES 82 PERCENT
NEAR SUNRISE...69 PERCENT NEAR NOON AND 66 PERCENT AT 4 PM.

                 AUGUST WEATHER IN SAN DIEGO

AUGUST IS NORMALLY OUR WARMEST MONTH WITH THE NORMAL HIGH OF 77.8
DEGREES, THE NORMAL LOW 67.3 DEGREES AND THE MONTHLY NORMAL OF
72.6 DEGREES.  EXTREMES SINCE THE ESTABLISHMENT OF THE NATIONAL
WEATHER SERVICE RECORDS IN 1872 WERE 98 DEGREES IN 1955 AND 54
DEGREES IN 1895.  READINGS OF 80 DEGREES OR HIGHER WERE FAR FROM
COMMON AND THERE HAVE BEEN 13 DAYS DURING THE ENTIRE PERIOD
WITH MAXIMUM RECORDS FOR THE DAY OF 90 DEGREES OR HIGHER.

RAIN SELDOM FALLS IN THE CITY AND 60 PERCENT OF THE AUGUSTS HAVE
BEEN WITHOUT A MEASURABLE AMOUNT.  THE MONTHLY RAINFALL AVERAGE
IS 0.10 INCH AND THE AVERAGE NUMBER OF RAINY DAYS WITH 0.01 INCH
OR MORE IS ONE.  HOWEVER, IN 1977 THERE WAS 2.13 INCHES FROM THE
REMNANTS OF TROPICAL STORM DOREEN.  ALSO, IN 1873 AND 1854 THERE
WERE 1.95 INCHES AND 1.36 INCHES RESPECTIVELY.  AS IN THE
OTHER SUMMER MONTHS, THUNDERSTORMS HAVE BEEN RARE AND NEVER
SEVERE EXCEPT IN THE MOUNTAINS AND DESERTS.  THE HIGHEST WIND
RECORDED AT THE NATIONAL WEATHER SERVICE BEING ONLY 29 MPH.

USUALLY SKIES BECOME CLEAR BY MIDMORNING AND AS A RESULT SUNSHINE
IS PLENTIFUL WITH A MONTHLY MEAN OF 70 PERCENT OF POSSIBLE
SUNSHINE AND IS THE 6TH SUNNIEST MONTH OF THE YEAR.  CLEAR DAYS
AVERAGE 15, PARTLY CLOUDY 12, CLOUDY 4 AND 1 DAY WITH HEAVY FOG.
THERE IS LITTLE CHANGE IN RELATIVE HUMIDITY FROM JULY, THE
AVERAGE BEING 81 PERCENT IN THE EARLY MORNING, 68 PERCENT NEAR
NOON AND 66 PERCENT IN THE LATE AFTERNOON.


                SEPTEMBER WEATHER IN SAN DIEGO

NATIONAL WEATHER SERVICE RECORDS SINCE 1872 SHOW THAT ABOUT ONE
THIRD OF THE TOTAL NUMBER OF DAYS WITH A TEMPERATURE OF 90
DEGREES OR HIGHER IN SAN DIEGO OCCURRED IN SEPTEMBER...FOR AN
AVERAGE OF ABOUT ONE EACH YEAR.  THESE HIGH READINGS WERE ALMOST
INVARIABLY ACCOMPANIED BY HOT...DRY EASTERLY WINDS IN THE COUNTY
KNOWN AS SANTA ANAS.  IT WAS DURING ONE OF THESE OCCURRENCES THAT
THE ALL TIME HIGH OF 111 DEGREES WAS RECORDED ON SEPTEMBER 26...
1963.  HOWEVER...MONTHLY AVERAGES HAVE BEEN CHANGED LITTLE BY THE
OCCASIONAL HOT DAYS...AND THE NORMAL MAXIMUM IS ONLY 77.1 DEGREES...
THE NORMAL LOW 65.6 DEGREES AND THE MONTHLY NORMAL 71.4 DEGREES.
THE LOWEST RECORDED WAS 50 DEGREES.

OUR DRY SEASON CONTINUES THROUGH SEPTEMBER AND IN MORE THAN HALF
OF THE YEARS NO MEASURABLE AMOUNTS OF RAIN WERE RECORDED DURING
THE MONTH.  THE NORMAL RAINFALL IS 0.24 INCH WITH THE GREATEST
MONTHLY TOTAL 2.58 INCHES IN 1939.

SEPTEMBER IS NORMALLY THE HEIGHT OF THE HURRICANE SEASON IN THE
EASTERN PACIFIC AND IS THE MONTH THAT DISSIPATING MAJOR TROPICAL
STORMS HAVE COME THROUGH SAN DIEGO.  THREE OF THE LAST FIVE TROPICAL
STORMS THAT CAME THROUGH SAN DIEGO OCCURRED IN SEPTEMBER WITH TWO
OF THEM IN AUGUST... TROPICAL STORM DOREEN...AUGUST 16 AND 17...
1977...TROPICAL STORM KATHLEEN...SEPTEMBER 9-12...1976...TROPICAL
STORM HYACINTH...SEPTEMBER 3-6...1972...TROPICAL STORM KATRINA...
AUGUST 31...1967 AND TROPICAL STORM KATHERINE...SEPTEMBER 17-19...1963
NORA SEPTEMBER 24-25...1997.
DURING A DISSIPATING TROPICAL STORM THAT ENTERED THE SOUTHERN CALIF-
ORNIA COAST AT SAN PEDRO...CALLED THE TEHACHAPI STORM OF SEPTEMBER 30...
1932...SAN DIEGO WINDS ATTAINED A SPEED OF 41 MILES PER HOUR THE RECORD
FOR THE MONTH.

AS A RULE THE NIGHT AND MORNING OVERCAST SKIES OF SUMMER BECOME
LESS PERSISTENT...BUT THE RELATIVE HUMIDITY REMAINS HIGH...
AVERAGING NEAR THAT OF AUGUST WITH 79 PERCENT IN THE MORNING...66
PERCENT NEAR NOON AND 65 PERCENT IN THE LATE AFTERNOON.  AT THE
TIME OF THE EAST WINDS...THOUGH...SEVERAL DAYS OF DRY WEATHER AND
EXTREMELY LOW HUMIDITY PREVAIL.  CLEAR DAYS AVERAGE 15...PARTLY
CLOUDY 9 AND CLOUDY 6 WITH AN AVERAGE OF 2 DAYS OF HEAVY FOG.

                OCTOBER WEATHER IN SAN DIEGO

MORE THAN SEPTEMBER...BUT 0.63 LESS THAN NOVEMBER.  THE

AVERAGE MINIMUM OF 53.6 DEGREES WHICH SHOWS THE GREATEST MEAN
RANGE OF ANY MONTH.  IT ALSO SHOWS A NOTICEABLE COOLING TREND AND
THE MEAN TEMPERATURE OF 61.8 DEGREES IS 5.8 DEGREES LOWER THAN
FOR OCTOBER.  SINCE HOT...DRY EASTERLY WINDS DECREASE DURING THE
MONTH...MAXIMUM TEMPERATURES OF 90 DEGREES OR HIGHER HAVE OCCURRED
LESS FREQUENTLY THAN IN SEPTEMBER AND OCTOBER.  AS A RULE...
TEMPERATURES SELDOM HAVE GONE ABOVE 80 DEGREES OR BELOW 40
DEGREES...ALTHOUGH 97 DEGREES WAS RECORDED IN 1977 AND 1976 AND 36
DEGREES IN 1919.

PRECIPITATION INCREASES WITH THE MONTHLY AVERAGE BECOMING 1.07
INCHES AND THE NUMBER OF DAYS WITH A MEASURABLE AMOUNT IS 5.
REGARDLESS OF THE FACT THAT THERE HAVE BEEN SEVERAL NOVEMBERS
WITH NO RAINFALL...THE RAINY SEASON MAY BE SAID TO BEGIN DURING
THE MONTH AS AMOUNTS IN EXCESS OF 2 INCHES HAVE BEEN RECORDED ON
SEVERAL OCCASIONS. THE GREATEST MONTHLY TOTAL WAS 5.82 INCHES IN
1965.

HIGH WINDS HAVE BEEN INFREQUENT BUT AN UNUSUALLY SEVERE STORM IN

MIDDLE OF DECEMBER. EVEN THEN TEMPERATURES ARE MODERATE, THE
DAILY HIGH AVERAGING 66.3 DEGREES, THE NORMAL LOW 48.9 DEGREES
AND THE MEAN 57.6 DEGREES OR 4.2 DEGREES COOLER THAN NOVEMBER.

NEVER DROPPED LOWER. ALTHOUGH THE HIGHEST READING WAS 88 DEGREES
IN 1963, TEMPERATURES ABOVE 80 DEGREES HAVE BEEN INFREQUENT.

THE NORMAL RAINFALL INCREASES TO 1.31 INCHES AND THE DAYS WITH

WIDELY AND HAVE RANGED FROM NONE IN SEVERAL DECEMBERS TO 9.26
INCHES IN 1921. A TRACE OF SNOW FELL ONCE, ON DECEMBER 18, 1967.
IN SOME NEARBY LOCATIONS AMOUNTS OF A HALF INCH OR MORE SNOW

LESS THAN IN NOVEMBER. CLEAR DAYS AVERAGE 14, PARTLY CLOUDY DAYS
