A look at what marathoners should expect from Mother Nature for today's big run!

As 36,000 runners race from Hopkinton, Mass., to downtown Boston in a 26.2 mile venture, the weather will be picture-perfect.
Following the tragic events that unfolded last year, there are many mixed emotions amongst runners this year for the 118th Boston Marathon. Fortunately, though, the weather will cooperate.

Temperatures this morning in the upper 30s will rebound to the middle 40s by the time the first wave of runners hit the pavement at 8:50 a.m. EDT. Sunshine will get filtered through mid and high clouds with temperatures warming to the upper 50s by the time the runners finish the 26.2 mile dash through Boston. Although the Southwest to Southeast breeze will be light at 5 to 10 mph, local effects between buildings will create a headwind and tail wind at times.

The weather today is right on cue with mid-April weather in Boston. The average low is 41 degrees and high is 56 degrees. The temperatures last year were right in line with mid-April climate averages in Boston but two years ago brought record heat. The high temperature reached 87 degrees on April 16, 2012, with nearly 2,000 runners seeking medical attention due to the weather conditions.

The race in 1905 was the hottest on record since the race started in 1897. The following is a recollection of temperatures during race day.


Based on the sample size below, the average temperature on race day is 63 degrees.

The marathon always takes place on Patriots’ Day in Massachusetts. This commemorates the Battle of Lexington and Concord, the first battle in the American Revolutionary War. Another part of the tradition is the Boston Red Sox home game on the third Monday in April.

Each year, the Red Sox play at home on Patriots’ Day at 11:05 a.m. EDT. This allows spectators to watch the ball game and then head to the finish line to cheer on the majority of the runners that will be finishing the marathon at this time.
