Boston rolled into Marathon Monday on the chilly side, with Logan Airport starting the day around 39°F under mostly sunny skies. Afternoon temperatures should top out near 50°F, but a steady west wind will keep it feeling cooler both along the coast and inland.
Afternoon Winds Pick Up
Winds are expected to blow from the west around 8 to 12 mph, with occasional gusts near 20 to 25 mph this afternoon, especially inland and along the South Shore. Those gusts could tug at light tents and make bike commutes a bit rough, and any scattered showers that pop up should be brief with totals under a tenth of an inch, according to the National Weather Service.
Marathon Monday And Commute Notes
The 130th Boston Marathon runs Monday, and road closures and parking restrictions will stretch along the entire 26.2-mile course, so plan alternate routes and give yourself extra time. The Boston Athletic Association recommends using the B.A.A. Racing App for participant tracking and official updates, and many finish-area streets are expected to be closed roughly between 8 a.m. and 6 p.m., per the B.A.A..
Tonight And Tuesday
A slight chance of light rain is in the forecast before 8 p.m., but most spots should stay dry with lows near 35°F along the coast. Inland and higher-elevation communities could drop into the low 20s overnight, and Tuesday looks drier and a bit milder with highs in the upper 40s, according to the National Weather Service.
Bottom line: layers are the smart move today, with a wind layer and a light jacket covering most conditions. If you are heading anywhere along the course, check the B.A.A. app and the National Weather Service forecast before you head out.
