Fire Island (FI) and NYC Weather

🌤️ Weather Forecast – September 1, 2026 (1 pm Update)

📍 NYC & Fire Island

The current rain should end soon. As we’ve seen, rainfall amounts have varied quite a bit across our area, which is typical in this type of weather pattern.

Later today through Thursday, we will remain positioned along a frontal zone separating very hot air to our south and west from warm air to the north. This will bring chances of showers and thunderstorms as we find ourselves around the “Ring of Fire” on the northern edge of an intense heat wave centered to our south and west. However, most of the time will be rain-free. The humidity will be sky-high, too. 🥵

Much more comfortable air will arrive by the end of the week and last through the weekend, with comfortable temperatures and much lower humidity. 😎
