Fire Island (FI) and NYC Weather

🌤️ Weather Forecast – June 1, 2026 (11:30 AM Update)

📍 NYC & Fire Island

Today through Saturday looks excellent, with a warming trend developing across the region. Away from the beaches, temperatures in NYC could exceed 90°F by next Saturday.

Next weekend is currently looking mainly dry and pleasant, although Sunday’s forecast will depend on the strength of a high-pressure system developing to our northeast. If the high becomes stronger, it should keep any rain well west of our area. If it is weaker, a few showers could move in on Sunday. Regardless, temperatures will be much cooler on Sunday compared to Saturday, especially along the coast.

Since hurricane season has begun, I’ve included the National Hurricane Center Tropical Weather Outlook link below. At this time, the potential development of El Niño later this year could help reduce overall Atlantic hurricane activity if it materializes as forecast.
