THE SUMMER MONTHS AT MANCHESTER WERE CHARACTERIZED BY VERY WARM AND
HUMID CONDITIONS AND BELOW NORMAL PRECIPITATION. HOWEVER, THAT IS
NOT HOW SUMMER BEGAN AS THE LOW TEMPERATURE ON JUNE 1 WAS 42
DEGREES. HOWEVER, WARMER AND MORE HUMID CONDITIONS ARRIVED TOWARD
THE MIDDLE OF JUNE AND PERSISTED, INCLUDING 5 OUT OF 6 DAYS ABOVE 90
DEGREES FROM THE 18TH THROUGH THE 23RD. IN FACT, IT WAS THE WARMEST
JUNE ON RECORD AT MANCHESTER AT 70.9 DEGREES. A PROLONGED STRETCH OF
DRY WEATHER BEGAN IN MID-MAY AND EXTENDED UNTIL THE LAST THREE DAYS
OF JUNE, ALTHOUGH MANCHESTER MISSED OUT ON THE HIGHER RAINFALL
TOTALS FOUND AROUND THE REGION. MORE FREQUENT RAINFALL WAS OBSERVED
FOR THE FIRST PART OF JULY TO HELP EASE THE ONGOING DROUGHT BEFORE
DRIER CONDITIONS RETURNED FOR THE LATTER HALF OF THE MONTH. OTHER
THAN A BRIEF RESPITE MID-MONTH, JULY WAS WARM TO HOT AND HUMID WITH
BOTH 4 STRAIGHT DAYS (JULY 18-21) AND 7 STRAIGHT DAYS TO CLOSE THE
MONTH OF TEMPERATURES AT OR ABOVE 90 DEGREES. LIKE JUNE, IT WAS THE
WARMEST JULY ON RECORD AT MANCHESTER. THE WARM AND HUMID CONDITIONS
GENERALLY CONTINUED THROUGH THE FIRST HALF OF AUGUST, INCLUDING A 4
STRAIGHT DAYS (AUGUST 9-13) AND 4 OUT OF 5 DAYS (AUGUST 21-
25) OF TEMPERATURES AT OR ABOVE 90 DEGREES. A COLD FRONT FINALLY
BROUGHT CONSISTENTLY COOLER AND LESS HUMID CONDITIONS FOR THE FINAL
WEEK HALF OF AUGUST. HOWEVER, THE ONGOING DROUGHT CONDITIONS
PERSISTED AS MANCHESTER SAW ITS 4TH CONSECUTIVE MONTH WITH BELOW
NORMAL PRECIPITATION.
THE AVERAGE TEMPERATURE FOR THE SUMMER WAS 74.4 DEGREES WHICH WAS
4.2 DEGREES ABOVE NORMAL AND THE WARMEST SUMMER ON RECORD. UNTIL
THIS YEAR, THE WARMEST SUMMER WAS IN 2018 WHEN THE AVERAGE
TEMPERATURE WAS 73.6 DEGREES. THE COOLEST WAS 64.9 DEGREES IN 1946.
A TOTAL OF 5.26 INCHES OF RAIN FELL WHICH WAS 5.96 INCHES BELOW
NORMAL AND THE DRIEST SUMMER SINCE 2016. THE HEAVIEST RAIN FELL ON
JULY 14 WHEN THUNDERSTORMS BROUGHT 1.01 INCHES OF RAIN. THE DRIEST
SUMMER WAS IN 2016 WHEN ONLY 5.21 INCHES OF RAIN WAS MEASURED. THE
WETTEST WAS IN 1938 WHEN 20.32 INCHES FELL.
HISTORICAL RECORDS AT MANCHESTER BEGAN IN 1885, BUT WITHIN THIS
RECORD THERE REMAIN NUMEROUS YEARS OF UNAVAILABLE DATA. DUE TO THIS,
HISTORICAL RECORDS SHOULD BE CONSIDERED INCOMPLETE AS SOME
SIGNIFICANT EXTREMES MAY BE MISSING FROM THE DATA. MORE CONSISTENT
MODERN RECORDS BEGAN IN 1998 AND CONTINUE TO THE PRESENT.
