Seattle

Here's the thing about Seattle that nobody tells you: it's not actually that rainy. It just rains constantly — like, a drizzle that lasts three months straight instead of one downpour. The annual rainfall sits at 1,185 mm, which is less than New York or Miami, but it's spread across 150+ days of light, persistent moisture. So if you're imagining dramatic storms, you're picturing the wrong place. The real Seattle story is about chasing the sun between May and August, when the city actually feels like the photographs.

May through August is when Seattle transforms. May kicks things off with average highs around 19°C (66°F) and actual blue skies starting to break through — the city shakes off its winter hibernation, Pike Place Market feels alive again, and the days stretch past 9 p.m. June and July are the crown jewels, with highs reaching 23–24°C (73–75°F), nearly 8 hours of daily sunshine, and long twilight evenings that make you want to sit outside until 10 p.m. August stays warm and mostly dry, though it's when prices peak and the tourist crowds are thickest. Each month has a different texture: May feels like Seattle's big exhale, June-July are pure golden-hour season, and August is when locals start eyeing September like a breakup that's coming.

Avoid November through January — and I mean really avoid them. This is when Seattle earns its reputation. December through February, you're looking at highs barely reaching 9°C (48°F), and the sky doesn't just cloud over, it commits to staying gray. The annual average high is only 15.8°C (60.6°F), which doesn't sound devastating until you're living through 60 consecutive days of overcast 8°C (46°F) mornings. January is the absolute nadir — the holidays are over, the novelty of winter is long dead, and the sun barely climbs above the horizon. Businesses scale back hours, ferries get delayed, and even locals admit the city feels a bit depressed. If you're not a Pacific Northwest native, these months will test you.

By 2026, Seattle's climate pattern is following the broader Pacific Northwest trend: warmer overall, with heat waves arriving earlier in summer and the rainy season compressing slightly. The traditional November–March wet spell is still dominant, but we're seeing more erratic weather — a sunny spell in January, then sudden cold snaps. Summer 2026 should track close to the 20-year average, meaning May–August remains your window. But here's the shift worth noting: September is becoming increasingly viable, with warmer, drier conditions creeping into what used to be a soggy transition month. If you're flexible, September 2026 might offer the best of both worlds — fewer crowds than July, better weather odds than October.
