Philadelphia is starting Saturday on a bright, breezy note, with temperatures near 70°F under mostly clear skies. West winds are already noticeable and will strengthen through the day, so any outdoor table setups or lightweight decor could take off on their own. Highs are expected to rise into the mid 80s this afternoon, making it warm but not sweltering. If you are planning to be outside, the morning or early evening will be more comfortable than the gusty midafternoon hours.
Afternoon Winds Pick Up
By this afternoon, west winds are forecast to increase to 10 to 15 mph with gusts up to 30 mph, especially in open areas and along the riverfront. A Small Craft Advisory is in effect for parts of the coastal waters into early afternoon, and forecasters are calling for a LOW rip current risk at Jersey Shore beaches today, which still means normal caution is advised for swimmers. Drivers of high profile vehicles should be ready for sudden crosswinds, and anyone with backyard furniture or umbrellas may want to strap them down before they end up in a neighbor’s yard. According to NWS Mount Holly.
Heat Resources Remain Available
The city recently declared a Heat Health Emergency and responded by opening cooling centers and extending pool hours so residents without air conditioning have a place to cool off. While this weekend’s temperatures are milder than the earlier heat wave, officials are still urging people who live in hot homes to make use of those public cooling options and to check in on older relatives and neighbors who may be more vulnerable. For a full list of cooling centers and tips on staying safe in hot weather, see the city’s announcement. According to City of Philadelphia.
Monday Brings Heavy Rain Risk
Attention now turns to Monday, June 22, 2026, when a passing system is expected to bring likely rain showers and scattered thunderstorms to the region, with some downpours that could be heavy. Current forecast guidance points to new rainfall totals of about one half to three quarters of an inch, with some models hinting at localized amounts above one inch, which would be enough to trigger brief urban or poor drainage flooding in spots. There is also a small risk of severe storms, mainly across the southern part of the forecast area, so it is worth having an indoor backup plan for any outdoor events. Forecast details come from NWS Mount Holly.
Bottom line, Saturday and Sunday are your sunnier, simpler days, but keep a close eye on Monday. Check a trusted weather app or forecast Monday morning before heading out, since timing and impacts could still shift. If you have big outdoor plans for Monday, you may want to move them to Sunday or take them inside while the rain and storms move through.
