How We Determined The Cities In Idaho With The Best Weather
To rank the most fair weather cities in Idaho, we used Saturday Night Science and the National Oceanic and Atmospheric Administration (NOAA) database, to see which cities in the Gem State get the best weather.
We used the following criteria to find the best weather:
- Number of sunny days
- Highest average low
- Average high deviation from 70 degrees
- Least amount of rain
- Least amount of snow
We ranked each city of over 10,000 people in Idaho from best to worst on each criterion. We then averaged each ranking into a weather quality index. The city with the best index, Nampa, was anointed the city with the best weather in Idaho.
Before we get too far, here are the annual precipitation rates for major cities: Boise City (11.9 inches), Nampa (10.4 inches), and Meridian (11.3 inches).
