Portland, Maine – Spring 2026 is shaping up to deliver a classic, back-and-forth season across Maine, with near normal precipitation and temperatures pointing to a balanced mix of late snow and steady rain.
According to NOAA’s Seasonal Temperature and Precipitation Outlook released February 19, Maine falls in an equal chances zone for both precipitation and temperature during March-April-May 2026. That means no strong signal toward a wetter, drier, warmer or colder season, leaving room for typical spring variability across the state.
In Portland and coastal York and Cumberland counties, precipitation will likely trend toward chilly rain events in March and April, with occasional wet snow mixing in during overnight cold snaps. Sea surface temperatures and onshore flow may keep coastal communities cooler at times, especially during early spring systems.
Farther inland in Bangor, Augusta and Lewiston, a more balanced split between rain and wet snow is possible through March. Northern Maine, including Presque Isle and Caribou, could see measurable late-season snow when colder air dips south, particularly during nighttime storms.
With near normal precipitation favored, river levels along the Kennebec and Penobscot basins should follow typical spring rises tied to snowmelt and rainfall timing rather than extreme swings.
Overall, Maine appears poised for a true transitional spring. Residents should prepare for fluctuating temperatures, a mix of snow and rain early in the season, and gradual warming toward May without a clear tilt toward extreme conditions.
