Nissequogue Location

40.9040, -73.1979

40.90399, -73.19789 View on OpenStreetMap →

Nissequogue sits at 40.9040°N, 73.1979°W, on the coast of New York, United States. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
