...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. Bagnor 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.
