Climate & Weather in Bellevue
Bellevue has a genuine Pacific Northwest marine climate -- mild, wet, gray winters (highs 40-50°F, lows 30-36°F) and dry, mild summers (highs 75-82°F, lows 55-60°F) -- with real, honest seasonal-affective-disorder relevance for movers from sunnier climates, treated here as a genuine lifestyle factor rather than a punchline.

Learn moreA Genuine, Real Marine West Coast Climate
Bellevue carries a real temperate marine (Koppen Csb/Cfb) climate, the same broad climate family as Seattle but with a real, disclosed difference: Eastside suburbs including Bellevue average 2-4 inches less annual precipitation than central Seattle (roughly 35 inches versus Seattle's 37-38 inches). This is genuinely different from every desert, continental, or humid-subtropical climate framing built for other markets in this project's broader dataset, and this record does not carry over any of that framing here.
Mild, Wet, Gray Winters Are a Real, Honest Lifestyle Factor
Bellevue winters average highs of 40-50°F with lows of 30-36°F -- genuinely mild by cold-winter-state standards, but real, consistently gray and wet, with the Pacific Ocean's marine layer producing frequent cloud cover especially from roughly November through March. Genuine seasonal-affective-disorder relevance is real for a meaningful share of movers relocating from sunnier or drier climates -- this record discloses this honestly as a real factor worth planning for (light therapy, deliberately scheduled outdoor time on clear days), not smoothed into a purely charming 'cozy and green' framing alone.
Summers Are Genuinely Mild and Dry -- the Real Reward Season
Bellevue summers average highs of 75-82°F with lows of 55-60°F, and July/August are genuinely the driest months of the year regionally -- a real, honest, and widely-cited reward season locals describe as some of the best weather in the country, precisely because it follows the real, wetter winter months disclosed above rather than existing in isolation from them.
No Hurricane, Tornado, or Extreme-Heat Risk Comparable to Other Markets in This Dataset
Bellevue carries zero hurricane risk (see the flood-hurricane-risk topic page for the fuller earthquake-focused hazard discussion) and no meaningful tornado risk. Unlike several Tier A+ markets covered elsewhere in this project's broader dataset, Bellevue does not carry genuinely extreme summer heat -- summer highs rarely exceed the mid-80s°F, a real, honest, and comparatively mild climate profile.
A Genuine, Honest Snow-Rarity Caveat
Snow is genuinely rare and generally light in Bellevue given its lower elevation and marine climate moderation, though the region can occasionally see a real, disruptive snow or ice event given comparatively limited local infrastructure built around clearing it (a genuine, disclosed contrast with snow-belt states elsewhere in the country) -- this research pass did not independently confirm a specific current average annual snowfall figure for Bellevue specifically, disclosed as a research gap rather than an invented number.
Key takeaways
- Bellevue carries a genuine temperate marine climate -- mild, wet, gray winters (40-50°F highs) and dry, mild summers (75-82°F highs) -- a real, honest Pacific Northwest identity, not ported from any desert or continental framing.
- Winters are real, consistently gray and wet from roughly November through March, with genuine seasonal-affective-disorder relevance for movers from sunnier climates -- disclosed honestly as a real factor to plan for.
- Summers are genuinely mild and dry, widely regarded locally as a real reward season precisely because it follows the wetter winter months.
- Bellevue carries zero hurricane risk and no meaningful tornado or extreme-heat risk relative to several other Tier A+ markets in this dataset.
- Snow is genuinely rare and generally light, though a specific current average annual snowfall figure was not independently confirmed this pass.
