🌡 The weather here, in general

Portland has four clear seasons. August highs average 84°F and February lows average 35°F.

The thermometer rarely spikes — only about 18 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Snow shows up most years — about 13 inches — but rarely in quantity. 30 freezing nights a year matter more, because the risk here is ice rather than depth.

Rainfall averages about 53 inches a year, wettest in December and driest in July.
