Portland woke up to clear skies and a mild 52°F on Monday, April 6, 2026, and the city is set to soak up one more dose of near‑summer warmth before cooler air barges back in. Bright sun will send inland neighborhoods into the mid to upper 70s this afternoon, with a light southwest breeze making things feel comfortably warm rather than blazing. If you have outdoor plans, this is the prime weather window of the week before stronger onshore flow moves in.
Afternoon Heat And Timing
Temperatures across the interior lowlands are expected to climb to around 78°F on Monday afternoon, with the hottest stretch landing in the mid to late afternoon. Winds should stay on the light side, around 1 to 6 mph out of the southwest. Several spots tied or broke record highs over the weekend, and inland areas are in for another notably warm day. The forecast details and timing come from NWS Portland.
