Harborside Half Marathon
Race Day Weather
Cool temps, adjust for wind
Runners will face starting temperatures around 50°F, rising slightly to 52°F by race finish. With wind gusts reaching 24 mph from the WNW, particularly challenging headwinds occur from Miles 2 to 5 and again at Mile 14. Humidity is high at 76%, so pacing should be conservative to manage energy levels. During the race, runners will benefit from tailwinds between Miles 7-12, which may assist in maintaining speed.
