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

The July 2025 season wrapped up with above average temperatures.
There was near average precipitation in northern Maine, but
significantly below average precipitation in central and southern
Maine.

Temperatures were above average throughout northern and central
Maine, with monthly averages generally ranging from 0.5-2 degrees
Fahrenheit above climatological normals. Monthly maximum
temperatures were above normal by generally 1-2 degrees, with
greatest deviations found in Millinocket, around 1.8 degrees
Fahrenheit. Both Caribou and Bangor recorded deviations around 1.5
degrees Fahrenheit above normal. Houlton high temperatures were
also above average by 0.9 degrees Fahrenheit. July 7th was one of
the hottest days for northern and central Maine this month, with
temperatures that reached into heat advisory criteria Downeast.

Monthly minimum temperatures were generally 1.3-2.3 degrees
Fahrenheit above normal, indicating some warmer overnight lows
throughout the month, with Millinocket and Houlton seeing the
highest deviations around 2.3 degrees Fahrenheit. Caribou and
Bangor were 1.3 and 1.5 degrees above normal, respectively.

Rainfall for the region was about average in northern Maine,
around the North Woods, central Aroostook, and northern portions
of the Central Highlands. Central Maine was below average, and
Bangor region and Downeast Maine were significantly below normal.
Caribou averaged 4.47 inches of rain this July, which is roughly
0.24 inches above average based on climatological normals. That
being said, Caribou evaporation amounts totaled up to 5.77 inches
in July this year, resulting in a precipitation deficit for the
area. Houlton averaged 4.00 inches of precipitation, which is 0.37
inches above normal. Things get drier as we enter central and
southern Maine however, with Bangor only averaging 0.81 inches of
rain this July, which is 2.35 inches below normal. This is the 4th
driest July on record for Bangor, since 1926. Millinocket only
averaged 1.84 inches of precipitation, which is 2.59 inches below
normal, and the 11th driest July on record since 1903. On July
1st, northern Maine was not in any drought, and as of July 29th,
there are still no drought conditions indicated in Maine. Short
term composite drought indicators have a potential for some
abnormally dry conditions to persist in central and southern
Maine, but clearing up by the mid/long term period.

For the August seasonal outlook, the Climate Prediction Center
(CPC) is predicting above average temperatures for the northeast.
There are no strong signals for above or below average
precipitation chances for August. Average temperatures for August
are usually in the mid to upper 60s. Average high temperatures are
generally in the mid to upper 70s, and average low temperatures
are generally in the mid 50s.
