Wettest towns in Idaho

Ranked by rain and melted snow in a normal year, 1991–2020, from NOAA’s gridded climate normals for each town. Neighboring towns on the same 5 km grid square have the same numbers, so each square is listed once, under its largest town. 63 towns with 2,500+ residents.

How this ranking works

We rank every town by rain and melted snow in a normal year, 1991–2020, from NOAA’s gridded climate normals for each town. The town with the highest figure ranks #1. Normals are 30-year averages, not a forecast, and each town’s Climate page shows its whole year month by month.

Temperatures and rainfall come from NOAA’s gridded normals, about 5 km (3 miles) square, read at each town’s center, so hills and coastlines are built in. Towns whose centers fall in the same square have the same numbers, so only the largest of them is listed.

Only towns with at least 2,500 residents are ranked; Census estimates for smaller places are too uncertain. Population and income: U.S. Census Bureau American Community Survey 5-year estimates. Climate: NOAA NCEI U.S. Climate Normals, 1991–2020. Town photos: Wikimedia Commons, credited on each town’s page.
