The start of the week in Seattle treated residents to the hottest day of the year — temperatures climbed to 30°C, and in the Cascade foothills and south of Puget Sound they nearly reached 32°C. But, as forecasters warn, this is only a temporary spike: by Wednesday temperatures will fall to a comfortable 21°C, then continue dropping. "We go up, we go down — a real rollercoaster," meteorologists joke.
By Wednesday evening clouds will roll in, and cool conditions will stick around at least until Monday. By Friday temperatures will not exceed 16–17°C, and rain will arrive along with the clouds. Pay particular attention on Saturday: forecasters predict thunderstorms with possible heavy downpours. So lightweight jackets and umbrellas will come in handy again.
If you want to enjoy a taste of summer, Tuesday is the best bet while the sun is still strong — but remember bay water remains icy and some beaches are not yet safe for swimming. Still, a true Seattle August is not far off: just a little more waiting, and the Puget Sound residents' favorite season will be here.
