Fenway Park Weather: Wind, the Wall, and Boston's Coastal Climate

By Kevin Roth, sports meteorologist. Data-driven ballpark guide for DFS players and bettors.

Climate

Fenway sits about a mile from Boston Harbor and roughly two miles from the open Atlantic at Nantasket. From April through September the park runs cool in the early months and warm-humid in July and August, with sea breezes from the east and southeast common on afternoon and evening games. Nighttime dew points climb into the mid-60s during typical summer stretches, and coastal fronts can drop temperatures 10 to 15 degrees inside a single evening game.

How wind plays here

Center field is to the northeast (bearing about 45 degrees from home plate), so a straight southwest wind blows out to right and center. Northeast winds, common with coastal storms and sea breezes, blow straight in from center. The Green Monster in left is 37 feet tall and only 310 down the line, which changes how left-field wind reads on batted balls. Wind out to left at 10 mph can turn routine flies into wall-scrapers, and wind blowing in from left at the same speed kills what would otherwise be doubles off the Monster.

For DFS and bettors

Watch sea-breeze onset in day-night doubleheaders and afternoon starts. The wind can flip 90 degrees between first pitch and the seventh. Wind out to left plus warm humid air makes left-handed pull-power profiles the primary beneficiary. Cold northeast wind and low dew points are among the toughest hitting conditions in the majors.
