Tsunamis and landslides are not rated for a single city here. Climate risk profile of United States of America
An earthquake's shaking at Seattle can reach 3.31 m/s², as strong as a once-in-475-years event.
New York: 0.61 m/s².
Seattle's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Seattle's climate will still be more like its own today than any other large city's. The nearest other is Bilbao (Spain).
+1.7°C
Mean temperature over the year
+2.3°C
Highest in the warmest month
+1.5°C
Lowest in the coldest month
+3%
Precipitation over the year
Under high emissions, Seattle would stay nearest its own climate today.
Its own climate today is 3.4 σ away. How close the match is: 4.5 σ to the climate of Bilbao today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 2 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Where else Seattle stands out
16 days
Days with 20 mm of rain or more in 2025
New York: 9 days.
Higher than in 75% of the world's 630 large cities
Hazards at Seattle
Read at the city's centre and compared with the Atlas's 630 large cities. Moderate emissions is the IPCC's scenario SSP2-4.5.

Flood depth is read in a single 1 km cell at the city's centre, in today's climate. Other parts of the city can still flood. The country page names the deepest point near a coastal city in 2080, so its figure can be higher. See how deep a river flood reaches around Seattle on the live map
