Runners and spectators at the Boston Marathon are in for “pretty nice” race day conditions Monday, according to National Weather Service forecasts.

“For Monday, we’re looking at a pretty nice day overall,” said National Weather Service meteorologist Emily McMinn. “We should start the morning off in the mid-40s or so about sunrise and increase to high 50s, maybe around 60 for a peak for the day on Monday for temperatures.”

Throughout the day, skies are expected to remain mostly sunny, NWS forecasts show. There should be “pretty light, sustained winds” starting out northerly in the morning, before turning westerly, and southerly in the afternoon hours, McMinn said.

Westerly winds are generally considered more favorable “tailwinds” for Boston Marathon runners. The breeze is expected to remain around five to seven miles per hour, McMinn said, with potential gusts picking up late afternoon to early evening to a max around 15 miles per hour.

Near sunset Monday, McMinn said, the city may see some “sprinkles” moving in for the nighttime hours. The rain “should not affect any of the runners,” the meteorologist added.

This year’s marathon should be cooler than last year, when the marathon Monday was the hottest day of April 2024 with a high of 73 degrees. The average high for mid-April is around 56 degrees, with an average low around 40 degrees.

The rest of the week is expected to remain warmer, with showers moving in on Tuesday, according to forecasts.

“Tuesday is going to be off and on showery through the day, but should see a high around the low 70s, so still pretty warm,” said McMinn.

The showers are expected to move out later in the afternoon, McMinn added, before Wednesday kicks off a “period of dryness for most of the week” and “nice reprieve for most folks.”
