What to Expect
Long Island will enjoy a pleasant stretch of dry, seasonable weather through Tuesday before humidity begins to increase on Wednesday. A stronger storm system may bring showers and thunderstorms Thursday into early Friday, with some storms potentially becoming strong. After that system moves through, the weekend looks excellent with sunshine, warm temperatures, and more comfortable humidity.
Tonight:
Mostly clear and comfortably cool with overnight temperatures falling into the upper 50s. A light northwest breeze will continue, especially near the coast, but winds will gradually diminish overnight. Great sleeping weather returns across Long Island, and it will be a pleasant evening for outdoor dining or beach walks.
Tuesday:
Sunny and seasonably mild with afternoon temperatures reaching the mid- to upper 70s. Humidity remains comfortable, and a light breeze shifts from the northwest to the southwest later in the day. Excellent conditions are expected for outdoor activities, commuting, and beach visits. Rip current risk remains moderate at ocean beaches, so swimmers should continue to use caution and stay near lifeguards.
Tuesday Night:
Partly cloudy and a bit milder with lows around the lower 60s. Light southerly winds develop overnight, beginning a gradual increase in humidity ahead of midweek weather changes.
Wednesday:
Partly sunny with increasing humidity and highs in the mid- to upper 70s. Most of the day looks dry, but a few scattered showers could develop during the afternoon or evening, especially inland from the immediate south shore. This does not appear to be a washout, but it would be wise to keep an umbrella nearby if you have late-day plans.
Thursday:
Partly sunny, warmer, and more humid with highs climbing into the lower 80s. A stronger weather system approaches from the west, bringing a better chance for showers and thunderstorms later in the day. Some storms could become strong, so monitor forecasts if you have outdoor plans for Thursday afternoon or evening.
Juneteenth (Friday):
Partly sunny and warm with highs in the mid-80s. A few lingering showers are possible during the morning and early afternoon, but improving conditions are expected later in the day. It will feel more summer-like with higher humidity, though conditions should gradually become more comfortable by evening.
Saturday:
Sunny and warm with highs in the mid-80s. Lower humidity and light winds will make for an excellent beach and boating day. Ocean conditions should be calmer than earlier in the week, though swimmers should still remain aware of local surf advisories.
Sunday:
Sunny and seasonably warm with highs in the mid-80s. Another beautiful summer day is expected across Long Island with comfortable humidity, light winds, and plenty of sunshine.
Beach & Coastal Concerns
A moderate rip current risk continues at Long Island ocean beaches through Tuesday due to lingering ocean swells. Swim only at guarded beaches and follow lifeguard guidance.
Minor coastal flooding remains possible during the nighttime high tide cycles through midweek, especially in the more vulnerable south shore back-bay locations. Any flooding should be localized and relatively minor.
