June Climate Summary for northern and eastern Maine (updated with new images)

Northern and eastern Maine monthly climate narrative

June 2004 averaged a little above normal for temperature and near

normal for rainfall for northern and eastern Maine, both with some

geographical distribution across the region.

Average temperatures actually ranged from near normal across the

Down East coast upwards to nearly 2.5 degrees above average across

the far northeast.  Believe it or not, the average of 63.0 degrees

at Caribou, which was 2.3 degrees above normal tied for the 6th

Warmest June (along with 1995, 1979, and 1973). The warmest June(s)

(2006 and 1976) of record at Caribou was 64.0 degrees, only 3.3

degrees above the 1981-2010 mean of 60.7 which is unusually low

variation even for a summer month, meaning that this record can be

easily broken if a warm and relatively dry regime were able to

dominate the entire month of June. Most locations experienced a warm

first 10 days this month followed by at or below normal temperatures

between the 11th and 26th and then a warm finish for the 27th and

30th when most locations inland from the immediate coast experienced

maximum monthly temperatures of upper 80s to around 90 degrees.

Rainfall ranged from 75 to 95 percent of average across northeast

Maine, and 100 to 120 percent of average across the remainder of the

region.  At Caribou, this was the driest June since 2007 when only

2.44 inches fell, with 2009 nearly as dry with 2.69 inches.  More

So, this June ended a streak (2010-2013)of 4 consecutive wet Junes

were significant portions of the region experienced 150 to 250

percent of average rainfall.  Significant to heavy rainfall days this

June across the region included the 6th...18th and 25th/26th.

The official Climate Prediction Center forecast for our region for

the month of July is calling for equal chances of above...near

normal or below normal categories for both temperature and rainfall

for the entire region. Average high (low) temperatures forJjuly for

the region generally range from 75 to 80 (55 to 60) degrees with

average rainfall ranging from around 3.00 inches along the Down East

coast upwards to 4.00 inches across northern and western higher

terrain locations.
