Holiday Weekend Heatwave: Oregon Into 90s, Coast as High as 80s and Clear Skies

(Portland, Oregon) – What could be summer's last blast is heading Oregon's way for the week and Labor Day weekend.

The National Weather Service (NWS) said there's a bit of a heatwave coming to the Oregon coast and certainly much of the state this week, after a brief spot of rain on Tuesday for many areas such as Portland, the Cascades, Bend, Eugene or Medford.

The Oregon coast gets rather warm – even warmer than usual in spots – with temps heading into the 70s or even 80s, according to the NWS. Other inland areas hit the 90s, while winds may be an issue in hotter areas of the state already prone to fire dangers.

The NWS said Friday will be the warmest, giving travelers around the state a little last-minute present as Labor Day Weekend kicks off.

“High temperatures will jump well into the 80s to lower 90s inland (and 70s to lower 80s along the coast),” the NWS said. “At this time Friday appear to be the warmest day with 40-70% chance for Willamette Valley & interior southwest Washington temps to exceed 95 F Friday and 20-50% for Saturday; and less than 10% to exceed 100 F. So, while warm, at least not as hot as the early July heat.”

The NWS noted that while temps in southern Oregon and eastern Oregon could be even higher, late night cooling off will offset the daytime temperatures and keep from turning into any heat alert situations.

Then, however, as Labor Day Weekend really gets underway, a large system offshore may bring threat of thunderstorms for areas like the Cascades and even parts of the I-5 Corridor – especially Sunday.

“Low pressure will move closer to the north Calif coast next weekend, bringing a chance of showers and thunderstorms for later Saturday and especially Sunday, mainly over Cascades,” the NWS said.

Oregon Coast Forecast This Week: the NWS said the place will literally have a sunny disposition. Clear skies will mostly rule the week, although some amount of winds may chill those 70 to 80-degree temps.

On the northern coast (Seaside, Cannon Beach, Manzanita, Rockaway Beach, Pacific City), Tuesday will get sunnier as the day wears on, hitting highs in the 60s. Wednesday is again in the 60s and very sunny, and Thursday scoots up to 75 degrees.

For the holiday weekend, Friday through Sunday stick to the 70s and partly cloudy with a fair amount of sunny conditions.

For the central Oregon coast (Lincoln City, Newport, Yachats and Florence), it's a similar forecast, again sticking in and around the 70s for the mid-late week and staying mostly clear until the late weekend.

However, beach towns just slightly inland like Nehalem, Astoria, Tillamook or Toledo can be a good ten degrees warmer.

For the southern Oregon coast, it's a warmer forecast, looking at the 70s and 80s for much of the area (Reedsport, Coos Bay, Bandon, Port Orford, Gold Beach and Brookings). The week starts off in the 70s but things heat up by Thursday, with the mid 80s possible along areas just outside of the beaches.

For inland Oregon: it's the low 90s for Portland, Salem, Bend, Eugene and Pendleton over the weekend, but slowly inches up from the 70s starting Tuesday.
