Seattle broke its record for rainfall from February through July last Sunday — with more than two months to spare, according to the National Weather Service.
As of Sunday, 22.87 inches of rain had fallen at Seattle-Tacoma International Airport since Feb. 1, surpassing the record set in 1972 when 22.81 inches of rain fell from Feb. 1 to July 31, weather-service meteorologist Josh Smith said Tuesday.
Fifteen inches is the average rainfall from February through July at the airport, which is where Seattle’s official weather data are recorded.
“Basically, we are well ahead of normal rainfall for February to July,” Smith said. “It’s not a special period, but it’s still pretty telling of how rainy it has been.”
Since February, the Seattle area has seen a larger than normal number of storm systems come through, and they dumped a lot of precipitation, Smith said. There weren’t as many high-pressure ridges as usual, which is what cleared the way for more storms.
So far this month, there have been three days with a half-inch of rain and one day with more than an inch, according to Weather Service data.
March, the rainiest month with 9.44 inches of rain, had eight days of more than a half-inch of rain and 20 days with at least some rain.
There’s long-term relief on the way for those who don’t like the Rainy City to be quite so rainy. This summer is expected to be dry — which is typical — and is forecast to be warmer than normal, Smith said. The average July high temperature is 75 degrees with 0.79 of an inch of precipitation.
For now though, the rainy trend is expected to continue through Thursday, followed by partly-sunny skies through next Tuesday, with high temperatures in the lower 70s. Saturday is forecast to be the nicest day, with sunny skies and highs near 74, Smith said.
“It will be a nice weekend, for once,” Smith said.
