A midday downpour pushed us into history.
Heavy showers in the noon hour lifted Seattle’s September rainfall total above 6 inches for the first time since weather observations began at Sea-Tac Airport, officially making this month the wettest September on record for Seattle. All told, we’ve received 6.17 inches this September, besting the previous high-water mark from September 1978 by nearly a quarter-inch—and quadrupling the monthly norm of 1.50 inches.
It rained yesterday like it never has in September before.
Seattle registered a staggering 1.71 inches of rain on Saturday, making it the wettest September day in the city since record-keeping began over 120 years ago. In doing so, Seattle toppled the previous one-day mark of 1.65 inches, set back in 1953 and tied in 1978, while simultaneously crushing the 65-year-old daily rainfall record for Sept. 28 of 0.83 inches.
It’s official: Today was the third-warmest September day on record.
The high temperature at Sea-Tac sprang up to 93 degrees late this afternoon—a mark eclipsed at the airport just twice before in the month of September (Seattle hit 98 on Sept. 2, 1988 and 94 on Sept. 7, 1981). In the process, the city established a new record high temperature for the day, sailing past the previous Sept. 11 high of 87 degrees from 2009.
Now that was a gullywasher.
Strong thunderstorms plowed through the metro area overnight, unleashing nearly an inch and a half of rain in the six hours between 11 p.m. and 5 a.m. With additional storms yesterday morning, Seattle easily crushed the daily rainfall record for Sept. 5, registering a staggering 1.09 inches—leaps and bounds above the previous mark of 0.36 inches from 1984.
46 years ago, deep into the Summer of Love, hearts weren’t the only thing ablaze in Seattle.
The mercury was also on fire.
Relentless heat dogged the city during August 1967, making it the hottest month in Seattle history—an honor that has stood the test of time ever since. No matter how you score it—by average high temperature (83.7 degrees), average overall temperature (71.1 degrees) or even average low temperature* (58.4 degrees)—August of ‘67 still tops the charts all these years later.
July has officially earned its place in history.
No measurable rain fell at Sea-Tac Airport last month, making it one of Seattle’s driest Julys on record—along with July 1960 and July 1958, both of which also skated by without any measurable precipitation. In addition, July 2013 goes into the books as just the sixth rain-free month ever observed at the airport—August 2012, September 1991, September 1975 and the two additional dry Julys are the others. Weather records at Sea-Tac stretch back to 1945.
