True Second Summer Hits Oregon / Washington Coast This Week, Inland Heatwave

(Long Beach, Washington) – Here's hoping you like last-minute heatwaves just before fall kicks in, because that's what you're going to get this week and weekend in areas like southern Oregon, the Willamette Valley and the Portland / Vancouver Metro area, with even the Oregon coast and Washington coast getting rather warm.

It is indeed “second summer” along the coastlines. In fact, the south Oregon coast will get into the 70s and 80s, while the central Washington coast may wind up a bit warmer than the upper 60s that will be making for pleasantries along the northern half of the Oregon shoreline.

The hottest weather comes today and Friday, with a slight cooling trend until Monday gets a little damp – except for the south Oregon coast.

Areas just somewhat inland from the coast, like Tillamook or Astoria, will be seeing temps in the 80s or higher.

According to the National Weather Service, a high pressure system off the coast is helping create this bout of warm, post-summer, summer fun.

“This will correspond to temperatures around 90 degrees in the interior lowlands, with model probabilities to reach 90 degrees sitting between 50 and 60 percent in most Willamette Valley locations,” the NWS said. “Friday will bring very similar conditions as high pressure remains in control. Although temperatures will be notably warm by mid September standards, do not anticipate any major heat risk concerns as overnight lows will still cool into the upper 50s.”

Washington Coast: Low 70s and mostly sunny to sunny are forecast for Thursday and Friday. Mostly sunny and 68 for Saturday, and then Sunday and Monday get a mix of sun and showers.

Northern Oregon Coast: Bright and sunny for Thursday and Friday with highs in the upper 60s, but some amount of wind. On Saturday, Sunday and Monday, clouds come in a little bit and temps drop into the lower 60s.

South Oregon Coast: The forecast is more similar to up north through Coos County, but Curry County's Port Orford to Brookings really see some warm conditions. That's partially because of the Chetco Effect and southern Oregon's 90-degree highs just inland.

Today gets a high near 83, while Friday and Saturday are mostly sunny to sunny with some haze, and temps in the upper 70s. Saturday, Sunday and Monday cool into the lower 70s with Tuesday hanging onto more sun and similar temps.

“Warm temperatures are expected north of Cape Blanco as well,” the NWS said.
