What August feels like

Hood to Coast runs in late August and turns half the state into a relay course. Some years the east wind carries wildfire haze down the Gorge and the air quality app becomes the first thing you check in the morning; other years it never happens at all.

Real rain shows up about 2 days all month; the rest stay dry. Humidity stays comfortable; the air never feels heavy. about 5 afternoons top 90°.
