Bright, Warm for Most of Marathon Monday

A beautiful weekend will give way to a beautiful Marathon Monday in the Boston area, although it may be a little warmer than many runners would ideally like.

Morning temperatures in Hopkinton will mainly be in the 50s, but as the last wave of runners launches closer to 11 AM expect readings around 62 degrees with sunshine overhead.

The temperature will keep climbing along the first half of the route, reaching a peak near 70 around Wellesley during the early afternoon hours. Also expect a light southwest wind along the first half of the route. That will act as a slight tail wind.

Along the second half of the course, runners will encounter into a sea-breeze. That means marathoners will face a slight head wind, and also cooler conditions. Temperatures will slide back into the low 60s by the time the finish line is reached in Boston. A few more clouds will be in the sky during the afternoon as well, with a cold front dropping down from the north.

All things considered this weather is fairly tranquil compared to some other recent years. In 2015, for example, temperatures were in the 40s and rain moved in during the race. On the flip side, in 2012, temperatures soared close to 90 degrees.
