Boston Marathon Forecast: Terrific Day For Runners And Spectators

BOSTON (CBS) - No news is good news!

The weather forecast remains unchanged for Marathon Monday. Why mess with perfection!

At this point, the only concern would be temperatures climbing into 60's during the afternoon, a bit warmer than most runners would like. Also, it's still a close call as to whether a sea breeze will develop in Boston in the afternoon.

If it did, it would be very weak and only bring slightly cooler air (50's) to the final mile or so of the course. Otherwise, tons of sunshine with a tail wind (southwest) for the majority of the race.

A terrific day for runners and spectators!

Sunrise in Hopkinton

Skies will be clear and temperatures will be cool early in the morning, 30-to-35 degrees with very little wind.

9 a.m. in Hopkinton

Race time! The first wave about to head off on their journey.  Very pleasant, sunny skies, temperatures rising into the 40's, with a light southwest breeze.

11 a.m. in Hopkinton

As the last wave of runners prepares for departure, there will be no weather issues.  In fact, conditions will be just about ideal, just a tad on the warm side. Sunny and calm, temperatures 50-to-55 degrees. Winds will be light, 5-15 mph out of the south-southwest (a tailwind).
The same conditions will exist in Boston at 11 a.m., as the Red Sox get underway at Fenway Park. Couldn't pick a better day to be at the ball park!

1 p.m. on the course

Lots of sunshine, perhaps some high, wispy clouds filtering the sunshine just a bit.  Temperatures from Framingham through Wellesley will be mild, ticking a degree or two higher each hour and now reaching 55-to-60. Southwest winds continue 5-to-15 mph. Closer to Boston, a light sea breeze (5-to-10 mph) may develop, knocking temperatures down a tad right in the city, 50-to-55.


3 p.m. on the course

Lots of runners coming down Boylston Street at this hour under nearly ideal conditions.

Inland, temperatures will soar into the mid 60's, a bit too warm for most. However, at this hour, most of the runners will be in or near Boston and may be feeling a refreshing, light sea breeze. If that ocean wind develops, temperatures in Boston would be closer to 50-to-55. Again, mainly sunny skies, and just some very high, thin clouds.

If you're going run 26.2 miles, you can't ask for much better weather than this!

We'll keep an eye on things over the next few days, but, at this point, I would not expect any major weather changes or issues.
