TEMPERATURES January was quite mild, in fact, one of the warmest on record. We had no Minimum Temperatures that even reached freezing this month as the low was only 35.5°. Though 16 days did manage to fall to ≤40°, Mins stayed above 40° from the 9th-17th. On the Maximum side, one day did manage to just reach 60° and 16 total days were ≥50°. When looking at the first and second halves of the month, temperatures averaged almost exactly the same…
With the end of January now upon us, it has certainly been a mild month in the Portland area. In fact, the Portland Airport (PDX) recorded its second-warmest January Mean Temperature since records began there in 1939, nearly 80 years ago! Only 4 days in the month averaged below the 30-year Normal, the greatest of these having just a -3.0° departure. When combining the longer-term record of the official downtown station locations with a Period of Record (POR) back to…
TEMPERATURES Average Temperatures were fairly steady throughout the month with a difference between the Maximum and Minimum of only 8.2°. The Average Max/Min/Mean Temperatures December 1st-15th vs. 16th-31st: 44.7°/36.6°/40.6° vs. 43.6°/35.2°/39.4°. There was no unusual warmth or cold – the month only featured 5 days reaching Maxima ≥50° and most of those just barely, while Minima reached ≤32° on 9 days, including 7 in a row from 20th-26th. The greatest diurnal temperature range was just 12.9° (12th, 19th, 27th), the…
TEMPERATURES A steady monthly temperature pattern occurred. The Average Maximum/Minimum/Mean Temperatures for November 1st-15th vs. 16th-30th were almost exactly the same: 52.0°/42.4°/47.2° vs. 51.9°/42.4°/47.2°. The month’s warmest weather waited until Thanksgiving time when the Minimum Temperature only dropped to 54.9° on the 22nd, several degrees above the Normal Maximum Temperature for the date. This warmth was balanced just a few days prior when the Min. Temp. dropped to 33.8° on the 19th (the low for the month), the coolest temperature…

Splitting the month in two, the Average Max/Min/Mean Temperatures for Oct. 1st-15th vs. 16th-31st were thus: 61.7°/44.7°/53.2° vs. 61.9°/48.1°/55.0°. This was mainly due to a persistent end-of-month easterly wind that funneled in mild air through the Columbia River…
TEMPERATURES: The normal steady monthly decline in temperatures occurred through this September. The Average Maximum/Minimum/Mean Temperatures for Sept 1st-15th vs. 16th-30th were thus: 82.9°/59.1°/71.0° vs. 68.1°/51.8°/60.0°. There were 5 days with Max. Temps. ≥90°, all occurring over the first 11 days of the month. A brief warm-up occurred at month’s end with 2 days reaching ≥80°, otherwise Maximum readings mostly stayed in the 50’s and 60’s over the latter half of the month. As far as Minimum Temperatures, there were…
It was a very dry and record-warm August in Happy Valley. TEMPERATURES: August started out very hot with two consecutive days exceeding 100° (2nd & 3rd), with the month’s maximum on the 2nd hitting 101.3°. Though quite hot for this area, these maximum temperatures were likely somewhat suppressed due to rather thick wildfire smoke blowing down from British Columbia and northern Washington. There were seven total days reaching ≥90°, five of which were ≥95°, including the two that exceeded 100°….
August started off with record heat on the 2nd and 3rd (103° and 105°, respectively) and, though no more Maximum Temperature records were set the rest of the month, the Mean Temperature was the warmest ever recorded for the Portland Airport (period of record back to 1940). The overall Average Maximum was 6.0° above normal, the second-highest August reading ever. Top-5 Highest August Average Maximum Temperatures: 88.1° (1967) 87.1° (2017) 86.2° (1986) 85.5° (1981) 85.0° (1972) Minimum Temperatures were not…

Fog occurred only on the 1st of the month when a Trace of drizzle was observed, the only precipitation during the entire month. PRECIPITATION: The dry streak that began on June 17th continued through July. As of July 31st, the consecutive-days streak without measurable precipitation had reached…
TEMPERATURES: Though there were many pleasant days early on, Maximum Temperatures certainly warmed in the month’s second half. The coolest period occurred from 8th-16th when it never even reached 70°, with the month’s low Max. Temp. of 58.1° observed on the 12th. The hottest weather began on the 19th, reaching >90° on the 24th and 25th. In fact, the 99.1° on the 25th was the highest temperature since 7/30/2015 when it soared to 100.8°. Minimum Temperatures were relatively cool through…
