Philadelphia is waking up to a partly cloudy sky around 70F this Monday morning, with a comfortable northwest breeze keeping the air from feeling sticky. High pressure is locked in through Tuesday, so you can bank on mostly sunny skies and a high near 79F for Monday, June 15. If your plans involve a run to the Jersey Shore tonight, be ready for higher-than-normal water levels during the evening high tide cycle.
Afternoon Breeze, Pleasant Day
Winds out of the northwest will run around 1015 mph, with occasional gusts near 20 mph, so it could feel a bit gusty at times this afternoon. Rain chances in the city are essentially zero, and any stray sprinkle that sneaks through should leave new rainfall amounts under a tenth of an inch. Monday night, June 15, stays mostly clear with a refreshing low near 59F.
Watch The Tides If You're Heading To The Shore
Minor tidal flooding is in the cards along the Atlantic coast and Delaware Bay with the Monday evening high tide cycle on June 15. Coastal Flood Advisories are posted for parts of New Jersey and Delaware from 8 PM Monday, June 15 to 2 AM Tuesday, June 16. Some local shorelines and low-lying waterfront streets may see spotty flooding right around high tide, so steer clear of driving through any standing water you run into. For the latest on which areas are covered and the exact timing, check the National Weather Service.
Midweek Showers, Then Heat And Storms
Things turn more unsettled by midweek. On Wednesday, June 17, there is a chance of rain showers, with scattered storms possible during the afternoon and evening. Forecasters peg the odds of showers and thunderstorms at around 50%. By Thursday, June 18, much hotter air builds back in, with highs near 92F inland and heat indices potentially pushing toward 100F along the I-95 corridor before any storms roll through. If heat is a concern, the city has already activated cooling resources and heat programs — see the Philadelphia Department of Public Health for cooling center locations and hours.
Boats, Beaches And The Commute
The Small Craft Advisory has been allowed to expire, but a brief period of 2025 knot gusts is still possible around daybreak into the morning, and seas should generally be 24 feet. With breaking waves around 2 feet or less, the rip current risk is expected to stay low Monday and Tuesday, though beachgoers should still listen to lifeguards. On land, sunny afternoons should keep the commute running normally today, but it is worth keeping an eye on the evolving forecast if you are banking on outdoor plans later in the week.
Plan Ahead
Enjoy the easy weather win today, and take a moment to sketch out a backup plan for Wednesday’s potential storms and Thursday’s heat. Check in with the National Weather Service and City resources before heading out, and avoid driving through standing water during high tides or any heavier downpours that pop up.
