New York City is starting Thursday, June 4, 2026, on a clear and comfortably cool note, with temperatures in the mid 60s and low humidity early on. Plenty of sunshine will carry most neighborhoods into the upper 70s by mid to late afternoon, a sweet spot for outdoor plans before the real heat builds later in the week. Light winds this morning will turn into a gentle southwest breeze as the day goes on.
Afternoon Winds And Temperatures
Highs will land near 79°F today, then slip a few degrees late in the afternoon as slightly cooler onshore air nudges in along the waterfront. Expect light southwest winds around 3 to 9 mph, with ferry routes and exposed piers feeling a bit breezier than city streets. Inland areas should run a couple of degrees warmer than coastal spots.
Friday Into Saturday Heat
Temperatures climb Friday and Saturday, so plan on highs near 86°F Friday and around 88°F Saturday, with some inland neighborhoods possibly tagging the lower 90s. Dew points are expected to hold mostly in the mid to upper 50s, which means heat indices should not run much higher than the actual air temperature. Along the coast, daytime sea breezes will keep things a bit cooler than farther inland.
Weekend Storm Chance
Unsettled weather returns late Saturday into Sunday as a frontal system moves through the region. Shower and thunderstorm chances increase Saturday night, then become more likely on Sunday. There is about a 40% chance of precipitation Saturday night and roughly a 60% chance Sunday, with the heaviest activity favored overnight into Sunday morning. If you are banking on outdoor plans this weekend, have a backup ready and keep an eye on forecast updates in case the timing shifts.
Boaters And Beachgoers
A Small Craft Advisory is in effect this afternoon for part of the western ocean waters (ANZ355) from 2 PM to 11 PM, and rip current risk is expected to rise toward moderate through Friday, according to the National Weather Service. Boat operators should secure loose gear and avoid the most exposed waters during stronger gusts, while swimmers should follow lifeguard instructions and posted signs. Check updated marine notices before heading out.
Planning And Context
