Seattle, Washington – A warm, dry stretch locks in over western Washington beginning Thursday as high temperatures climb toward the low 80s by the weekend — offering ideal conditions for outdoor plans but raising summer heat safety concerns, especially in Seattle and along the I-5 corridor.
According to the National Weather Service in Seattle, skies will gradually clear Thursday, with a high near 73°F and calm wind becoming north-northwest around 6 mph. By Friday and into the weekend, highs will rise to 81°F with sunny skies expected each afternoon. Nights remain mostly clear and mild, with lows ranging from 55°F to 61°F.
The warming trend means hotter pavement and drier air — especially relevant for travelers on I-5, where tire pressure, overheating, and visibility can become issues. Locals are encouraged to hydrate, limit mid-afternoon exertion, and ensure pets and vulnerable residents stay cool.
This pattern holds steady through at least Monday, making it the longest uninterrupted sunny stretch since late June. With no rain expected, now’s a good window for lawn care, weekend hikes, or visiting Puget Sound’s outdoor attractions.
Highs will peak Tuesday at 85°F, marking the warmest day in the outlook. While no official heat advisory has been issued yet, sensitive groups should take early precautions as temperatures creep higher.
