The Boston Marathon will take place this Monday, but the weather won’t cooperate. The race begins in the morning in Hopkinton, Massachusetts and ends up just over 26 miles later in downtown Boston. The race follows a generally eastward path. More than half of the race, the runners are facing the northeast direction, then by mile 18 through the end of the rave, they are traveling in an eastward direction most of the time. We explained this because this easterly direction will be impacted by the weather.

First of all, a light to moderate rain is forecast throughout the day in eastern Massachusetts. The rain is forecast to begin Sunday evening and will persist through the overnight hours. By sunrise, it will turn into a steadier rain, so rain will likely be falling at the start of the race. This rain will continue into the afternoon hours, and the intensity of this rain may even increase. Then between 6 and 10pm, the rain will come to an end in the Boston area, but the race would have already ended for most runners.

Another component to the forecast are the temperatures. Generally, temperatures in the 50s are the most conducive for these marathons. With this year’s Boston Marathon, however, temperatures will be on the cooler side. At the start of the race in the morning, temperatures will be in the mid 30s. By the afternoon and evening, temperatures will rise into the mid 40s as the runners reach Boston. According to Boston Meteorologist Eric Fisher, the weather “will probably be the highest impact since 2012 (heat) and wettest since 2007.”

The last weather component that will have an impact on the runners in this year’s Boston Marathon will be the wind. Winds through the duration of the race will be coming out of the east or northeast. Gusts in the morning will be up to 40 mph. Then in the afternoon and evening, winds will remain strong, ranging from 30-45 mph. Sustained winds will rise from 10 mph to 25 mph as the runners head east.
