Long Island Weather for Your Town & Hamlet

Home base of Tempest Station #212066. Heavily moderated by Long Island Sound water temperatures with persistent onshore afternoon breezes and steep elevation moraine gradients.

Buffered by Stony Brook Harbor and Smithtown Bay. Prone to localized coastal stratus and sea fog during spring warm-ups; winter snowfall buffered by sound thermal inertia.

Rolling hilly topography along Harbor Hill Moraine. Sound air mass provides maritime cooling in summer, with occasional heavy localized convective showers along ridge lines.

Protected deep harbor basin. Temperatures run slightly warmer at water level than surrounding bluffs; Asharoken isthmus subject to coastal overwash during severe nor'easters.

Nissequogue River basin serves as a natural cold air drainage funnel on calm nights, producing rapid radiational cooling and morning river fog.

High bluffs directly exposed to northerly gales across Long Island Sound. Sharp elevation difference from beach level to cliff tops frequently creates 3°F vertical gradients.

Boundary transition between North Shore hills and East End agricultural plains. Strong Sound breeze keeps afternoon highs 5°F cooler than inland Brookhaven.

World-famous coastal resort corridor bounded by the Atlantic Ocean and Peconic Bay. Strong summer sea breezes, coastal upwelling fog banks, and mild late-autumn temperatures.

Surrounded by water on three sides at the extreme tip of Long Island. Cold ocean upwelling frequently keeps spring/summer highs 10°F below NYC. Atlantic winter nor'easter battleground.

Famous microclimate dichotomy: Gabreski Airport sits in the porous Pine Barrens frost hollow with record freezing temperatures, while Dune Road is ocean-moderated.

Sheltered historic whaling port tucked between Gardiners Bay and Shelter Island Sound. Less ocean swell than the Atlantic shore, with calm maritime afternoon breezes.

Surrounded by Shinnecock Bay, Tiana Bay, and Great Peconic Bay. Tidal flow through Shinnecock Canal equalizes water temperatures; high humidity and maritime fog.

Great South Bay gateway with direct ferry links to Fire Island. Strong afternoon marine breeze penetrates up to Sunrise Highway, capping inland summer heat.

32-mile barrier island exposed 100% to Atlantic marine air. High humidity, intense UV index, zero urban heat island, and gale-force wind exposure during coastal nor'easters.

Direct Great South Bay frontage across from Fire Island Pines. Renowned for consistent summer sailing winds and shellfish aquaculture microclimate.

South Shore transportation and maritime transit hub. Strongest marine influence occurs between 1:00 PM and 6:00 PM when bay breeze pushes inland toward Sunrise Highway.

Coastal bayfront village leading south to Robert Moses State Park and Fire Island Inlet. Heavy ocean fog and spray during southerly wind regimes.

Smith Point County Park and Narrow Bay marshlands. Highly sensitive to astronomical high tides and storm surges; extreme humidity and fog in summer.

Dense oceanfront barrier island in southwest Nassau. Zero obstruction to Atlantic storms; famous for ocean breeze moderation and coastal flooding susceptibility.

The geographical split point between the North and South Forks. Peconic River basin creates high thermal variability; warmer in summer days than coastal points.

Historic maritime harbor village on the North Fork. Influenced by both Long Island Sound and Shelter Island Sound, offering steady breezes and cooler summer afternoons.

Heart of Long Island Wine Country. Narrow landmass bounded by sound and bay creates an extended frost-free growing season ideal for European vinifera grapes.

The easternmost tip of the North Fork. High-velocity tidal rips through Plum Gut generate turbulent water and intense local fog banks; windiest spot on the North Shore.

Island sanctuary nestled between the North and South Forks. Surrounded 100% by Peconic waters, dampening daily temperature extremes year-round.

Central spine of Long Island surrounding the island's largest glacial kettle lake. Frequent battleground for north/south sea-breeze convergence fronts along the LIE corridor.

Deep in the Long Island Central Pine Barrens. Sandy soils and minimal moisture retention create the island's steepest diurnal swings — summer afternoons near 90°F plunging into the 40s by dawn.

Mid-island glacial moraine spine. Elevated above coastal fog but removed from direct maritime breezes, often recording the hottest summer daytime highs in central Suffolk.

Historic Hempstead Plains in central Nassau. Urban heat island effect from surrounding metropolitan density raises nighttime temperatures 3°F to 6°F above eastern Suffolk.

South Shore Nassau coastal plain. Direct access to South Oyster Bay and Jones Beach Causeway; strong afternoon sea-breeze cooling and coastal canal surge tracking.

Nassau Gold Coast with deep harbor inlets and high bluff elevations. Sound water buffers coastal extremes; inland Syosset moraine ridges trigger elevation snow lines.

Westernmost Nassau peninsulas fronting western Long Island Sound and Manhasset Bay. Closest proximity to NYC weather radar (KOKX Upton / Central Park hybrid).
