..MEDFORD OREGON WEATHER REVIEW: MAY 2026
MAY 2026 WAS CHARACTERIZED BY MINOR SWINGS FROM WARM TO COOL, BUT
THE WARM WEATHER WON OUT DESPITE A STRETCH OF 6 STRAIGHT DAYS OF
BELOW NORMAL TEMPERATURES TO END THE MONTH. THIS WAS PRIMARILY
BECAUSE THE MONTH BEGAN WITH 14 STRAIGHT DAYS OF ABOVE NORMAL
TEMPERATURES. THERE WERE 19 DAYS OF HIGH TEMPERATURES AT OR ABOVE
80 DEGREES, WHICH WAS JUST 3 DAYS SHY OF THE MONTHLY RECORD OF 22
DAYS SET IN MAY 1924. INTERESTINGLY, ALTHOUGH MAY 2026 WAS WARM,
HEAT WASN'T EXTREME WITH THE HIGHEST TEMPERATURE OF THE MONTH, 89
DEGREES, OCCURRING ON 3 CONSECUTIVE DAYS FROM THE 21ST-23RD.
PRECIPITATION WAS SPARSE. THUNDERSTORMS ON THE 3RD BROUGHT GUSTY
WINDS WITH A PEAK WIND GUST OF 44 MPH RECORDED AT THE AIRPORT, BUT
ONLY 0.04" OF RAIN. THIS WAS ALL THE MEASURABLE PRECIPITATION WE
COULD MUSTER UNTIL A STRETCH FROM THE 26TH-29TH BROUGHT THE BULK
OF THE MONTH'S PRECIPITATION, 0.45".
THE STRETCH OF COOLER, WETTER WEATHER AT MONTH'S END WAS PRECEDED
BY AN UNUSUAL WIND STORM ON MEMORIAL DAY. A STRONG COLD FRONT
MOVED ONSHORE IN THE MORNING, BUT MIDDAY HEATING IN THE ROGUE
VALLEY ALLOWED FOR STRONG VERTICAL MIXING DURING THE EARLY-MID
AFTERNOON. THIS RESULTED IN A FEW HOURS OF UNUSUALLY STRONG WNW
WINDS THAT BROUGHT TREE LIMBS DOWN AND KNOCKED OUT POWER TO MANY
AREA RESIDENTS. MOST OF THE STRONGEST WIND STORMS EXPERIENCED
HERE IN MEDFORD OCCUR WITH A WIND FROM THE SE DUE TO THE VALLEY'S
ALIGNMENT AND CHANNELING THROUGH LOCAL TERRAIN. BUT, THE WNW
(NON-THUNDERSTORM) WINDS MEASURED AT THE AIRPORT PEAKED AT 60 MPH
WITH SUSTAINED 2 MINUTE WINDS OF 41 MPH, WHICH WERE BOTH THE
HIGHEST OF THE MONTH.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 63.1 DEGREES, WHICH IS
2.7 DEGREES ABOVE NORMAL. THE AVERAGE MAXIMUM TEMPERATURE WAS 78.4
DEGREES, WHICH IS 4.5 DEGREES ABOVE NORMAL. THE AVERAGE MINIMUM
TEMPERATURE WAS 47.9 DEGREES, WHICH IS 1.0 DEGREES ABOVE NORMAL.
THE HIGHEST TEMPERATURE FOR THE MONTH WAS 89 DEGREES WHICH
OCCURRED ON THE 21ST-23RD. THE LOWEST TEMPERATURE FOR THE MONTH
WAS 37 DEGREES WHICH OCCURRED ON THE 18TH.
THERE WERE 23 CLEAR DAYS, 5 PARTLY CLOUDY DAYS, AND 3 CLOUDY
DAYS.
TOTAL PRECIPITATION FOR THE MONTH WAS 0.49 INCHES WHICH IS 0.85
INCHES BELOW NORMAL. TOTAL PRECIPITATION FOR THE WATER YEAR
(BEGINNING OCTOBER 1ST) IS 13.44 INCHES WHICH IS 3.26 INCHES BELOW
NORMAL. CALENDAR YEAR PRECIPITATION IS 6.54 INCHES WHICH IS 2.80
INCHES BELOW NORMAL.
THE AVERAGE WIND SPEED FOR THE MONTH WAS 5.3 MPH. THE FASTEST
RECORDED TWO-MINUTE WIND SPEED WAS 41 MPH FROM THE NORTHWEST
WHICH OCCURRED ON THE 25TH. THE PEAK WIND WAS 60 MPH FROM THE
NORTHWEST WHICH OCCURRED ON THE 25TH.
