...OCTOBER 2025 CLIMATE NARRATIVE FOR NORTHERN/EASTERN MAINE...

The October 2025 season, overall, was above climatological normal
for daily maximum, minimum, and average temperatures. Precipitation
totals for northern and eastern Maine were below average throughout
the month. Drought conditions continued, and deteriorated,
throughout the state during October, impacting agriculture and
drying up wells throughout the state.

Similar to September, precipitation and drought were the primary
weather concerns for October. All climate sites recorded below
average precipitation. Bangor had the largest deficit, receiving
only 2.69 inches of precipitation, which is 1.89 inches below
climatological normal for October. Houlton received 3.24 inches of
rain, and Caribou received 3.26 inches, each recording 0.8 and 0.73
inch deficits, respectively. Millinocket recorded 3.94 inches of
precipitation, which is a 0.61 inch precipitation deficit. There
were some wetting rain storms that moved through northern and
eastern Maine, but as shown by the above deficits, none resulted in
drought relief.

At the beginning of October, northern Maine, including northern
Aroostook, northern Penobscot, northern Piscataquis, and northern
Somerset, were abnormally dry. Southern Aroostook, central
Penobscot, and central Piscataquis experienced moderate drought.
Northern Washington, northern Hancock, central and southern
Penobscot, southern Piscataquis were in severe drought. Coastal
Washington and Hancock counties were in extreme drought. Conditions
worsened by the end of the month, given prolonged precipitation
deficits. Portions of northern Somerset, northwestern Aroostook,
central Aroostook and northern Penobscot, upgraded to moderate
drought. Central and southern Aroostook, northern and central
Penobscot, Piscataquis, and portions of northern Somerset all
became, or maintained, severe drought. No significant severe weather
occurred in October.

Temperatures were above normal at all climate sites, with average
temperatures generally 2-5 degrees above climatological normal.
Monthly maximum temperatures were significantly above average for
October, generally 3-5 degrees above climatological normal.
Caribous average high temperatures were the warmest this month,
being 4.9 degrees above normal. Millinocket was a close second,
being 4.7 degrees above climatological normal. Houlton daily high
temperatures were 4.5 degrees above climatological normal. Bangor
was 3 degrees above normal.

Caribou broke its all-time high temperature record for the month of
October, 83 degrees, during a heat event on October 6th. During this
same event, Millinocket reached 85, and Houlton reached 84 degrees,
both of which also broke previous all-time high monthly records.
Bangor recorded 84 degrees, which was the second highest temperature
record, right behind a 86 degree record in 1968. The past 5 years
have been within the top 10 warmest Octobers, with records dating
back to 1953.

Monthly minimum temperatures were generally 1-2 degrees above
climatological normal. Millinocket had the largest deviation, being
2 degrees above normal. Caribou low temperatures were 1.9 degrees
above normal. Bangor minimum temperatures were generally 1.4 degrees
above normal. Lastly, Houlton had minimum temperature values roughly
1.3 degrees above climatological normal.

For the month ahead, Climate Prediction Center (CPC) is showing a
likely probability of above normal temperatures for the entire state
of Maine, alongside a chance for some above normal precipitation.
For the next three months, there is a chance for above normal
temperatures in Maine. There is, however, no strong signal for
precipitation outlooks for the upcoming season at this time.
