April 4 in Auburn splits the difference between winter and spring — historically, you're looking at a 59° high and 38° low, with a coin-flip chance of rain (53%). The date's range is wild though: it's hit 78° as recently as 1966 and dropped to a hard freeze at 26° back in 1918.
Auburn's weather has serious range. The all-time high of 106° during the June 2021 heat dome and the all-time low of -10° in January 1950 tell you this valley can get pushed to extremes — and a single December day in 1949 dumped 6 inches of rain, while January 1950 buried the area under 11 inches of snow in one storm.
July 23–29 is Auburn's sweet spot, with average highs peaking at 80° — dry, mild, and about as good as the Pacific Northwest gets. If you're avoiding rain, steer clear of late December, which averages 1.6 inches of precip in a single week. Winters are cool but not brutal, with January highs hovering around 45–46°.
