New York City wakes up warm, muggy, and mostly cloudy on Thursday, June 18, 2026, with temperatures near 68°F and dew points in the upper 60s. It will not stay calm for long. As the day wears on, winds pick up, showers begin to move in, and any outdoor plan that cannot roll with the punches risks getting washed out by a round of afternoon thunderstorms bringing gusty winds and brief heavy downpours.
Afternoon Storms And Gusty Winds
A warm front lifts through the region this morning, with a chance of rain showers between about 8 a.m. and 2 p.m., followed by a greater chance of showers and thunderstorms in the early to late afternoon. Forecast highs are near 84°F, and southwest winds of 14-20 mph are expected to strengthen, with gusts around 35-40 mph possible, especially if any thunderstorm forms. The main window for stronger storms runs roughly from 1 p.m. to 6 p.m. across the metro, according to the National Weather Service.
Spotty Severe Threat
The severe threat today is on the spotty side. Storm coverage may stay isolated, but any cell that manages to organize could pack damaging wind gusts and a burst of intense rain. Western and interior parts of the metro have a better shot at seeing the stronger storms, with activity tending to weaken as it slides east. Keep an eye out for warnings this afternoon and avoid hanging out under large trees or near unsecured structures when winds start to kick.
Dangerous Rip Currents At Ocean Beaches
Out at the ocean beaches, the story is all about the surf. A high rip-current risk and rough water are in play through this evening, with onshore swell and 4-7 foot breaking waves making swimming hazardous. If you are heading for Coney Island, Rockaway, or any Atlantic-facing stretch of sand, stick to areas with lifeguards on duty and follow posted flags and instructions from beach staff. For local beach guidance and earlier coverage of rough conditions, see how rough surf put NYC beachgoers on alert.
What To Do
Consider delaying nonessential ocean swims and secure loose patio or balcony items before the gusty winds move in. Drivers should plan for on-and-off downpours that can cut visibility and slow surface transit. If you are caught in a rip current, float or tread water and swim parallel to the shoreline until you are out of the pull, then angle back toward the beach; alert a lifeguard or call 911 in an emergency. Ferry riders and small-craft operators should be ready for choppy conditions and possible delays this afternoon.
Juneteenth Outlook
Friday, Juneteenth (June 19), looks like the reward for getting through today: noticeably calmer and mostly sunny with a high near 80°F, so many holiday plans appear to be in good shape once winds ease. Keep an eye on evening updates, but the heaviest weather is expected to stay focused on Thursday afternoon and early evening.
