This summer was Seattle’s driest on record and had the most 90-degree days in any calendar year.
SEATTLE – After a slow start to the summer, the summer season has been in full swing, bringing with it dry conditions and persistently high temperatures.
Now that summer is officially coming to an end — the fall equinox is Thursday at 6:03 p.m. — let’s take a look back at the summer of 2022 that’s set to go down in Seattle’s record books.
The summer of 2022 is officially the driest summer on record in Seattle. During the summer, which lasts from June 21 to September 21, Seattle has seen just 0.5 inches of rain. This is well below the seasonal average and surpasses the previous driest summer, which was 2017. In the summer of 2017, 0.52 inches of rain fell.
Prior to the summer of 2017, the driest summers on record saw at least 2.5 cm of rain.
On average, Seattle sees 2.45 inches of rain between June 21 and September 21.
The summer of 2022 was not only dry but also warm after a very cold spring season. Temperatures were well above average this summer.
Temperatures soared to 90 degrees or warmer 13 times in Seattle, a record. This is the most common time in a calendar year that Seattle hit 90 degrees or warmer, surpassing 2015, which had 12 days of 90 degrees or warmer.
This summer brought not only the most 90-degree or warmer days in any calendar year, but also the longest consecutive 90-degree or warmer stretch in recorded history.
Seattle hit 90 degrees or more for six consecutive days from July 26-31, beating 2015 and 1981, both of which experienced five consecutive days of 90 degrees or warmer.
While a short, autumn-like cool-down is expected for the first few days of autumn (see the latest forecast here), the forecast from the National Climate Forecasting Center favors above-average temperatures over the next few weeks.
The extended outlook looks promising. We are entering our third consecutive La Niña winter. These oceanic and atmospheric conditions typically favor a more active weather pattern for western Washington, increasing the likelihood of cooler temperatures and above-average rain and snowfall.
