...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.
