New Yorkers are waking up to a murky start on Sunday, May 10, 2026, as dense morning fog sits over the city with temperatures stuck in the low 50s. A Dense Fog Advisory is in effect, warning that pockets of locally dense fog could make driving tricky in spots. Forecasters expect the fog to burn off by mid-morning, giving way to a warm, humid afternoon with a chance of showers and isolated thunderstorms later in the day.
Fog And Afternoon Storms
Fog is expected to hang around through about 10 a.m., and visibility in low-lying neighborhoods and near the water could drop to a quarter-mile or less. If you are on the road early, slow down, leave extra room between cars, and stick to low-beam headlights.
Once the fog lifts, a south wind will help push afternoon highs into the mid to upper 70s, peaking near 78°F in the urban corridor, while the south shore and coastal Southeast Connecticut stay a bit cooler. Scattered showers and a chance of thunderstorms are most likely between about 2 p.m. and 4 p.m., with roughly a 30% chance of precipitation in the afternoon. The timing could still wiggle a bit as a front approaches. This forecast comes from the National Weather Service.
Marine And Commute Impacts
Out on the water, coastal waters and the south-shore bays are under a marine dense-fog advisory through midday, and Small Craft Advisories are posted for parts of the ocean as swells build. That combination is cutting visibility for ferries and shoreline transit, so riders should be ready for delays or trimmed schedules on waterfront routes and give themselves extra time if their commute depends on a boat.
Before heading out, check your route for last-minute changes. Current notices are posted on NYC Ferry service alerts.
Tonight And This Week
Showers are expected to become more likely along the coast tonight and linger into Monday morning, although most spots should only see light rainfall totals. A larger and slower-moving system is on track for midweek. Showers should become more widespread from Wednesday night into Thursday, with ensemble guidance pointing to at least a half-inch to three-quarters of an inch of rain and the potential for localized higher amounts.
If you are planning outdoor events later in the week, keep an eye on the forecast for changes in timing and for the possibility of gusty south winds on Wednesday. These details and timing come from the National Weather Service.
Quick Tips
In the fog, slow down, use low-beam headlights, and leave extra stopping distance, especially on wet roads. Mariners and small-craft operators should hold off on nonessential trips while the marine dense-fog advisory is in effect. If you have outdoor plans this afternoon, consider shifting them indoors or to earlier in the day in case a brief heavy downpour moves through.
