2025 Boston Marathon: Early weather forecast

Boston Marathon

“For Marathon Monday, we should be up around 60 degrees. That’s nice for runners. Maybe a little bit actually on the warm side, but the relative humidity should be generally low. Great for spectators on Marathon Monday as well.”

With Marathon Monday just a week away, athletes and spectators alike may be anxious to learn the forecast.

Here’s a very early look at the weather, according to Boston-area meteorologists.

National Weather Service: “Mostly sunny, with a high near 62. West wind 5 to 9 mph.”

WCVB’s Cindy Fitzgibbon: “Warming late week with 70° likely Saturday—late day showers with a cold front that clear us out for Easter Sunday and Marathon Monday”

Eric Fisher, WBZ: “Great looking Easter and Marathon Monday.”

Easter and the Boston Marathon now on the 7-day! A few showers/a rumble tomorrow. Wednesday is the cool/gusty day of the week. After snow last Saturday, this Saturday should be the warmest day of the year so far. Great looking Easter and Marathon Monday. #wbz pic.twitter.com/OQMlNlGmOl
