This is the first time in a long time that high temperatures mostly stay in the 70s through the next 10 days. That said, the normal average high temperature is right at 80 degrees in Islip. So, this will only be slightly below average temperature weather.
Plan on getting outdoors when you can, too! It is beyond comfortable with low humidity for the rest of the week and only a couple of spotty showers returning on Friday. Labor Day Weekend looks amazing!
The ocean is still choppy for boating but improving with three-to-four-foot waves today. The rip current risk is also slowly improving, but you should always only swim where there is a lifeguard!
