As Boston Marathons go, the average temperature is in the lower 60s and most of the time it’s dry. This year we’re still going to remain mainly dry, but on the cooler side of average, nice for the runners but a bit chilly if you’re a spectator.

A cold front will pass through the area Sunday night along with showers. These showers will be with us much of Sunday, but will come to an end Sunday evening. As the front presses offshore, the wind will turn to the west and colder air will arrive.

At sunrise, which is just before 6 a.m. Monday, temperatures will be in the 30s across much of the region. This is quite chilly, and runners who will be waiting in Hopkinton might want to plan on some of those disposable heaters for your feet or your hands to keep warm before the race.

Skies will be partly sunny throughout the race, although at times it may look threatening, and you could even see a quick little sprinkle or shower, especially in the afternoon. This is due to the cool air which will be present over us being heated by the strong, now August-strength sunshine.

The wind will be favorable hitting runners mostly at their backs from a westerly direction, pushing them along at five to 15 miles per hour with higher gusts at times.

For those concluding the race around noon, you expect temperatures about 48 degrees in Boston, topping out at around 50 before falling back after 3 p.m. Monday night features readings down in the 20s away from the coastline and right around freezing elsewhere.

All in all, when you consider strong headwinds, big heat, driving rain or even cold damp weather this year’s marathon will be one of the better ones. Let’s see how fast the runners can go in these favorable conditions.
