HAPPY VALLEY, OREGON, WEATHER: OCTOBER 2017

TEMPERATURES It was a topsy-turvy month as the second half was actually warmer than the first half, not the usual steady decline as we move through Autumn. 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°.

Temp. was 50.0°, well…
