New York woke up to a classic summer morning on Monday, July 20, 2026: clear blue skies, a light breeze and temperatures parked in the mid 60s, around 64°F. The city is on track for a bright, warm day with a high near 82°F and light northeast winds, practically begging for lunches in the park and rooftop hangs. Just do not get too attached. A wetter, stormier pattern is lined up for Tuesday into Wednesday, and it looks like the atmosphere plans to make up for lost time.
Today
Sun should dominate through the afternoon, with highs topping out near 82°F and light northeast winds in the 2 to 8 mph range. Humidity stays in the comfortable zone, so it will feel like a textbook summer day rather than a sauna. By Monday night, clouds start to creep in and skies turn partly cloudy, with a low near 70°F as winds shift and pick up out of the south. It is a strong day for parks, patios and rooftops, but a light layer will not hurt once the evening breeze kicks in.
Tuesday Into Wednesday
Things turn busy quickly on Tuesday, July 21, 2026, and into Wednesday, July 22, 2026. Showers and thunderstorms are likely, with the main action expected from late Tuesday morning through the afternoon and on into Tuesday night. According to the National Weather Service, most spots around the area could pick up 1 to 2 inches of rain, with localized pockets of 2½ to 3 inches. Some of those storms may pack damaging wind gusts, hail and a low-end tornado risk.
Ocean waters will be rough enough for a Small Craft Advisory, in effect from 8 AM Tuesday, July 21, 2026, through about 6 AM Wednesday, July 22, 2026. Rip currents at ocean beaches could ramp up from moderate to high late Tuesday, a setup that can catch even strong swimmers off guard. Flash flooding is possible in low-lying or poor-drainage spots, so Tuesday night commutes could be slow, soggy and filled with the usual chorus of honking.
Beaches, Boats and the Commute
If you are beach-bound, Monday is your safer swim window. Check the flags and follow lifeguard guidance, because once Tuesday's higher rip-current risk arrives, ocean swimming turns from "refreshing" to "not a great idea." Ferry riders and coastal drivers could run into delays if storms push inland, and utility crews often stage along the shoreline ahead of events like this. For a reminder of how messy these setups can get, see our earlier coverage of storm drama bearing down on NYC.
Boaters should steer clear of exposed waters during the advisory window and make sure small craft are secured overnight Monday into Tuesday. A choppy ocean, gusty storms and smaller vessels are not a combination you want to test.
How To Prepare
Have a Plan B ready for any outdoor plans on Tuesday, and tie down or bring in loose furniture, grills and anything else the wind might decide to relocate. Keep your phone charged so you can receive weather alerts. If you encounter flooded streets, do not try to drive through them, turn around, do not drown. Residents in low-lying or flood-prone areas should be prepared to head to higher ground if local advisories or evacuation guidance come out. Keep an eye on official forecasts and local alert systems for updates and any changes to watches or warnings as the storms get closer.
