After 90-plus-degree days Wednesday and Thursday, 2015 has put considerable ink in the hot-weather record book.

Stand-up paddleboarder Spencer Slaven-Lazzar, a contestant in Seafair’s Northwest Paddling Series Championship race Saturday, said he remembers watching a hot-weather paddleboard race in Oregon once where the eventual winner jumped off his board into the water midrace just to cool off.

In the scorching-hot weather predicted for his race, a 90-degrees forecast, would he consider a similar plunge?

“I don’t know. If I get a big enough lead, maybe I’ll try that tactic,” he said, laughing.

I-90 closures for Blue Angels

The Blue Angels are back this year at Seafair, which means the Interstate 90 bridge will be closed 11:50 a.m.-2:40 p.m. Friday-Sunday while the elite Navy pilots practice and perform their air show over and around Lake Washington.

The bridge high-rises will still be accessible to pedestrians and cyclists.

After 90-plus-degree days Wednesday and Thursday, 2015 has put considerable ink in the hot-weather record book.

The mercury rose to 94 degrees at Seattle-Tacoma International Airport on Thursday afternoon. That meant Seattle recorded 10 days in 2015 where the temperature was at least 90 degrees, snapping the record for 90-degree days in a year, set in 1958, according to the National Weather Service.

But that’s just the latest.

The warmest June ever in Seattle belongs to 2015, and by more than 3 degrees. This Fourth of July was the hottest on record in Seattle, at 92. And Seattle tied its record for consecutive days in which temperatures hit at least 80 degrees in early July, with 15 straight.

This July will likely be warmest on record, too, said meteorologist Ni Cushmeer of the weather service. It’s also threatening August 1967 for the warmest month ever recorded in Seattle.

Averaging the high and low temperatures of each day, July, so far, has clocked in at 70.7 degrees, compared with 71.1 in 1967. The official count from Thursday and Friday has to be at least 76.5 for July to claim the crown.

Record-keeping for the hottest month began in the 1890s.

The Seattle area also has a streak of 47 consecutive 70-degree days, but the 2003 record is 61 days, meteorologist Mike McFarland said.

As for Seattle’s latest record, the most 90-degree days in a year, the record should continue to grow. Meteorologist Johnny Burg said the predicted high Friday is 95. The predicted high Saturday is 90, and 88 Sunday.

Berg said he expects “cool air to come in” from the Pacific early next week, with 81 as Monday’s high and 78 Tuesday.

Long term, little rain is forecast. A weather-service climate model says precipitation in the next three months is supposed to be below normal.

The heat has come with side effects.

Air conditioners are selling fast, and firefighters are battling brush fires like a game of whack-a-mole. With heat came drought, which has adversely affected crops in the state, and salmon, too.

Summertime in Seattle is best known for its beauty. As an ode to the season, Seattle Times photographers seek out the elements that define its essence: earth, wind, water and fire, to pay tribute before the rain returns. Read more.

And Seattle, Tacoma and Everett are urging water conservation, though they expect the shortage won’t be too severe.

At least hikers were happy this spring when they could hike usually snow-heavy areas, months early.

Slaven-Lazzar said rather than swimming a leg of the Seafair paddleboard race to cope with the heat, paddleboarders might wear hydration packs or take hydration tablets during the 2-mile race at 5 p.m. at Genesee Park on Lake Washington. That’s even though the race should last just 20 to 25 minutes, he said.

“It should be extremely hot for us,” he said.
