Boise, ID – The National Weather Service (NWS) Boise reports that November 2025 is shaping up to be one of the warmest on record for the Treasure Valley.
As of November 23, Boise’s average temperature stands at 49.3°F, which is 7.6 degrees above normal. This makes it the second-warmest November ever recorded in the city, just behind the 1934 record of 50.0°F.
Records for Boise date back to 1875, and this year’s warmth edges out previous notable years such as 1903 (49.0°F) and 2016 (48.9°F).
Forecasters say the mild streak will end soon, with a cold front expected later this week that will bring temperatures back to seasonal averages for late November.
