It’s going to feel much more like summer across Long Island over the next several days, with warm temperatures, plenty of sunshine, and only a few interruptions from passing clouds. For today, expect mostly sunny skies and beautiful weather conditions from morning through evening. High temperatures will reach the 70s across much of the Island, with low 80s possible in parts of Nassau County. If you're heading outdoors, keep in mind that the UV index will be very high, so sunscreen is a must. At the beaches, temperatures will be cooler but still pleasant, generally in the upper 60s to low 70s under the sunshine.


Tonight will be comfortable with partly cloudy skies and seasonable temperatures. Overnight lows will settle into the 50s across most neighborhoods. The pleasant weather continues into Thursday with abundant sunshine and another warm afternoon. Highs will range from the 70s to lower 80s, while parts of western Nassau County could climb into the mid-80s.
By Friday, the warming trend continues as humidity begins to creep upward. Look for mostly sunny skies with a few afternoon clouds developing. Temperatures will climb into the 80s for many inland locations, while the South Shore and East End remain cooler in the 70s thanks to the ocean breeze. Western Nassau County could once again reach the mid to upper 80s during the afternoon.
The warm weather sticks around for the first half of the weekend. Saturday will feature a mix of sun and clouds, with increasing cloud cover during the afternoon. Even so, it will remain quite warm, with highs in the 80s inland, 70s along the shoreline, and some spots in western Nassau County approaching 90 degrees. By Sunday, clouds increase and temperatures ease back into the 70s. We'll also be tracking the chance for some late-day rain showers as slightly cooler weather returns to the region.
