SUMMER 2017

THE SUMMER OF 2017 WAS RELATIVELY COOL AND DRY IN THE SOUTH BEND
AREA. JUNE SAW NEAR NORMAL TEMPERATURES BUT JULY AND AUGUST WERE
BOTH BELOW NORMAL. PRECIPITATION FOR ALL 3 SUMMER MONTHS WAS BELOW
NORMAL.

THE AVERAGE TEMPERATURE FOR THE SUMMER SEASON WAS 69.9, 1.2 DEGREES
BELOW NORMAL. THIS RANKED AS THE 30TH COOLEST SUMMER AT SOUTH BEND.
THERE WERE JUST 3 DAYS WITH A HIGH TEMPERATURE OF 90 OR HIGHER, ALL
OCCURING IN JUNE ON THE 11TH, 12TH AND 14TH. THIS RANKED 8TH AMONG
ALL SUMMER SEASONS WITH THE FEWEST NUMBER OF 90 DEGREE DAYS. THE
YEAR 1915 HOLDS THE RECORD WITH NO 90 DEGREE DAYS. THERE HAVE ONLY
BEEN 12 OTHER SUMMER SEASONS WHERE THE MAXIMUM SUMMER TEMPERATURE
DID NOT EXCEED 92 DEGREES. THE COOLEST SUMMER SEASON HIGH
TEMPERATURE WAS 88, SET IN 1915.

SUMMER PRECIPITATION WAS 8.36 INCHES, 3.19 INCHES BELOW NORMAL. THIS
RANKED AS THE 33RD DRIEST SUMMER ON RECORD. THERE WERE 30 DAYS WITH
MEASURABLE PRECIPITATION BUT NO SINGLE DAY WITH AN INCH OR MORE OF
RAINFALL.

THE SEASONAL STATISTICAL RANKINGS WERE CREATED USING AN ALLOWABLE
MAXIMUM OF 3 MISSING DAYS FOR THE SEASON. MANY EARLY YEARS HAVE
INCOMPLETE MONTHLY DATA.

BELOW IS A MONTH BY MONTH REVIEW OF THE SUMMER.

JUNE

...A DRY JUNE WITH NEAR NORMAL TEMPERATURES...

JUNE BEGAN RATHER DRY WITH LESS THAN MEASURABLE PRECIPITATION
OCCURRING ON THE FIRST 7 DAYS AND NONE OF THE FIRST 28 DAYS
RECORDING 0.50 INCH OR GREATER OF RAIN. JUNE ALSO BEGAN WITH COOL
TEMPERATURES WITH 5 OF THE FIRST 8 DAYS HAVING BELOW NORMAL AVERAGE
TEMPERATURES. HOWEVER, THE FOLLOWING 10 DAYS, FROM THE 9TH TO THE
18TH, HAD ABOVE NORMAL TEMPERATURES WITH 7 OF THOSE DAYS HAVING
AVERAGE TEMPERATURES OF 10 DEGREES OR MORE ABOVE NORMAL. THAT 10 DAY
PERIOD HAD 5 OF THE 6 DAYS OF THE FIRST HALF OF THE MONTH WITH
PRECIPITATION TOTALING 0.10 INCH OR GREATER INDICATING A WETTER
PERIOD. THE PERIOD FROM THE 19TH TO THE 30TH WAS GENERALLY A COOLER
PERIOD WITH 7 DAYS OF BELOW NORMAL TEMPERATURES, 3 DAYS OF ABOVE
NORMAL TEMPERATURES AND 1 DAY OF AVERAGE TEMPERATURES. THIS PERIOD
ALSO CONTAINED THE 2 DAYS WITH THE HIGHEST DAILY PRECIP TOTALS FOR
THIS MONTH SO IT ENDED ON A RATHER WET NOTE. IN TERMS OF CROP
CONDITIONS, EARLY MONTH DRYNESS RESULTED IN REDUCED TOPSOIL MOISTURE
FOR CROP DEVELOPMENT, BUT MID MONTH SHOWERS AND STORMS HELPED TO
IMPROVE TOPSOIL MOISTURE AND RECOVER CROP CONDITIONS.

THE AVERAGE MONTHLY TEMPERATURE WAS 69.8...0.7 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 51ST WARMEST JUNE ON RECORD. THE HIGHEST
TEMPERATURE WAS 92 ON THE 12TH AND THE COOLEST TEMPERATURE WAS 46 ON
THE 1ST. THERE WERE 9 DAYS WITH AN AVERAGE TEMPERATURE DEPARTURE OF
5 DEGREES OR GREATER, AND THERE WERE 5 DAYS WITH AVERAGE TEMPERATURE
DEPARTURE OF -5 DEGREES OR LESS.

MONTHLY PRECIPITATION TOTALED 2.42 INCHES...1.37 INCHES BELOW
NORMAL. THIS RANKED AS THE 37TH DRIEST JUNE ON RECORD. MEASURABLE
PRECIPITATION FELL ON 14 DAYS BUT ONLY 4 DAYS RECEIVED GREATER THAN
0.24 INCH OF RAIN. THE LARGEST AMOUNT OF PRECIPITATION THIS JUNE
FELL ON THE 29TH WITH 0.52 INCH. INCIDENTALLY, THE NEXT DAY, THE
30TH, CAME WITHIN 0.01 INCH OF TYING THAT AMOUNT.

JULY

...BELOW NORMAL TEMPERATURES AND PRECIPITATION THIS MONTH...

TEMPERATURES AVERAGED A TOUCH BELOW NORMAL IN JULY AND PRECIPITATION
WAS SPREAD RATHER EVENLY THROUGHOUT THE MONTH LEADING TO A SLIGHTLY
BELOW NORMAL JULY. THERE WERE A COUPLE PERIODS OF WARM TEMPERATURES
AND VERY HUMID CONDITIONS, BUT THE HIGH TEMPERATURE NEVER REACHED 90
DEGREES DURING THE MONTH. THERE HAVE BEEN 10 OTHER YEARS AT SOUTH
BEND WHERE THE HIGH TEMPERATURE DURING JULY DID NOT REACH 90 DEGREES
AND FOUR OF THOSE YEARS HAVE BEEN SINCE 2000. THE LAST OCCURRENCE
WAS IN 2014. WHILE THE MONTH WILL OFFICIALLY GO DOWN AS BELOW
NORMAL, THERE WERE LOCATIONS SURROUNDING THE AIRPORT THAT SEEN MUCH
MORE IN THE WAY OF RAINFALL.

THE AVERAGE MONTHLY TEMPERATURE WAS 71.9 DEGREES, 1.1 DEGREES BELOW
NORMAL. THIS RANKED AS THE 38TH COOLEST JULY ON RECORD.

THERE WAS 3.75 INCHES OF PRECIPITATION, 0.25 BELOW NORMAL. THIS
RANKED AS THE 74TH DRIEST JULY ON RECORD.

AUGUST

IT WAS ANOTHER RELATIVELY COOL AND DRY SUMMER MONTH AT SOUTH BEND.
THE AVERAGE MONTHLY TEMPERATURE WAS MORE THAN 3 DEGREES BELOW NORMAL
AND PRECIPITATION WAS MORE THAN AN INCH BELOW NORMAL. THE
COMBINATION OF DRY AND RELATIVELY COOL WEATHER DID MAKE FOR A
COMFORTABLE MONTH WITH ONLY A FEW WARM AND MUGGY DAYS.

THERE WERE JUST 7 DAYS DURING AUGUST WITH AN AVERAGE TEMPERATURE
ABOVE NORMAL AND THERE WAS ONLY ONE DAY, THE 21ST, WITH AN AVERAGE
TEMPERATURE MORE THAN 5 DEGREES ABOVE NORMAL. THE REMAINING 24 DAYS
OF AUGUST SAW 3 DAYS WITH NORMAL AVERAGE TEMPERATURES AND 21 DAYS
WITH BELOW NORMAL TEMPERATURES. THE LAST 10 DAYS OF THE MONTH WERE
ALL BELOW NORMAL AND THERE WAS A STRETCH OF 11 STRAIGHT DAYS FROM
THE 4TH TO THE 14TH WITH BELOW NORMAL TEMPERATURES.

DESPITE ALL OF THE BELOW NORMAL TEMPERATURES...AUGUST OF 2017 WAS
JUST THE 13TH COOLEST AUGUST ON RECORD AT SOUTH BEND WITH AN AVERAGE
TEMPERATURE OF 68.0. THIS WAS 3.3 DEGREES BELOW NORMAL. THE COOLEST
AUGUST ON RECORD WAS 1915 WITH AN AVERAGE TEMPERATURE OF 65.5. THE
HIGHEST TEMPERATURE THIS AUGUST WAS 88 ON THE 16TH. ONLY 7 OTHER
AUGUST MONTHS HAVE HAD COOLER MONTHLY MAXIMUM TEMPERATURES AND THERE
HAVE BEEN 19 MONTHS OF AUGUST WHERE THE HIGH TEMPERATURE DID NOT
REACH 90 DEGREES. THE COOLEST TEMPERATURE WAS 45 ON THE 25TH. THIS
RANKED AS THE 25TH COOLEST AUGUST TEMPERATURE ON RECORD. THE RECORD
COOLEST AUGUST TEMPERATURE IS 40 SET IN 1911, 1927 AND 1965.

PRECIPITATION FOR THE MONTH WAS JUST 2.19 INCHES, 1.57 INCHES BELOW
NORMAL. THIS RANKED AS THE 30TH DRIEST AUGUST ON RECORD. THE YEAR
1950 HOLDS THE RECORD FOR THE DRIEST AUGUST WITH JUST 0.32 INCHES OF
PRECIPITATION. AUGUST 2017 HAD JUST 7 DAYS WITH MEASURABLE
PRECIPITATION. NEARLY HALF OF THE MONTHLY RAINFALL FELL ON THE 3RD
AND 4TH WITH A COMBINED 1.06 INCHES BEING RECORDED.
