Manchester, New Hampshire – Blistering summer heat will grip New Hampshire Wednesday, July 16, with Manchester bracing for a high near 93°F and heat index values pushing 99. Residents along I-293 and downtown should prepare for the hottest day of the month so far. Health officials urge everyone to limit outdoor activity, stay hydrated, and never leave children or pets in parked cars.
According to the National Weather Service, temperatures will peak by early afternoon. Calm winds and mostly sunny skies will intensify the heat. Patchy fog may slow the early morning commute, but the primary concern is rising temperatures. The heat will linger into Wednesday evening, with overnight lows only dipping to 72°F.
Local agencies recommend checking on elderly neighbors and planning errands for the morning or late evening. If you must travel, use caution on major routes like I-293 and NH-101, where asphalt can reach hazardous temperatures. Charge your devices, prepare for possible power surges, and consider using fans or air conditioning.
Thursday brings a 50% chance of showers and thunderstorms after 11 a.m., breaking the heat and offering some relief. However, the humidity will stay high, and storms could bring gusty winds. By Friday, Manchester expects mostly sunny skies and slightly cooler highs in the mid-80s. The weekend features a return to partly sunny weather Saturday, with a 40% chance of showers Sunday as another summer front approaches.
Warnings remain in effect for heat through Wednesday night. Stay tuned for further updates as the weekend weather develops.
