November 2025 Monthly Narrative for Northern and Eastern Maine

...November 2025 Climate Narrative for Northern/Eastern Maine...

The November 2025 season was below climatological normal for daily 
maximum temperatures, precipitation, and snowfall. Daily minimum 
temperatures were above normal. Drought conditions persisted, 
continuing to dry up wells throughout the state. That being said, 
portions of central and Downeast Maine had drought improvement. 

Similar to October, precipitation and drought were the primary 
weather concerns for November. All climate sites recorded below 
average precipitation. Millinocket had the largest deficit, 
receiving 2.49 inches of precipitation, which is 1.61 inches below 
climatological normal for November. Bangor received 2.52 inches of 
precipitation, which is 1.32 inches below normal. In terms of 
snowfall, Bangor only recorded 0.6 inches of snow, which is 3.7 
inches below normal for November. Houlton received 2.56 inches of 
rain, and Caribou received 3.10 inches, each recording 1.05 and 0.25 
inch deficits, respectively. Caribou, however, did have slightly 
above normal snowfall amounts, recording 11 inches of snow 
throughout the month, while the climatological normal is 10.4 
inches. There were some wetting storms that moved through northern 
and eastern Maine that provided a bit of relief for Downeast Maine. 

At the end of October, portions of northern Somerset, northwestern 
Aroostook, central Aroostook and northern Penobscot, were in 
moderate drought. Portions of central and southern Aroostook, 
northern and central Penobscot, Piscataquis, and northern Somerset 
all became, or maintained, severe drought. The Bangor region, 
Hancock, and Washington county all recorded Extreme Drought. By the 
end of the month, northern Somerset, northwestern and central 
Aroostook, northern Piscataquis, Bangor region, and portions of 
Hancock and Washington counties, were included in severe drought. 
Overall, drought conditions deteriorated in the Crown of Maine, but 
the rest of northern, central, and Downeast Maine improved. 
Hydrological impacts include dry well reports. There was some 
improvement in lake, pond, river and stream levels. 

Temperatures were relatively close to normal at all climate sites, 
with average temperatures generally 1 degree above or below 
climatological normal. Monthly maximum temperatures were below 
average for November, generally 1-2 degrees below climatological 
normal. Millinocket had the coldest daytime highs, 1.7 degrees below 
normal. Caribou’s average high temperatures were 1.1 degrees below 
normal. Bangor was 1 degree below normal. Lastly, Houlton daily high 
temperatures were 0.5 degrees below climatological normal. 

Monthly minimum temperatures were generally 1-2 degrees above 
climatological normal for Caribou, Houlton, and Millinocket. 
Millinocket had the warmest overnight lows, being 1.8 degrees above 
normal. Houlton had minimum temperature values roughly 1.4 degrees 
above climatological normal. Caribou low temperatures were 1.1 
degrees above normal. Bangor minimum temperatures were the only 
station below normal, with overnight lows generally being 0.9 
degrees below normal.  

For the month ahead, Climate Prediction Center (CPC) is showing a 
probability of below normal temperatures for the entire state of 
Maine, alongside a chance for some above normal precipitation. For 
the next three months, there is no strong signal for above or below 
normal temperatures or precipitation in Maine. CPC currently has a 
La Nina Advisory issued, where the United States can expect La Nina 
conditions to persist, before transitioning to ENSO-neutral in early 
2026.
