Mid-Beach Location

25.8145, -80.1226

25.81448, -80.12262 View on OpenStreetMap →

Mid-Beach sits at 25.8145°N, 80.1226°W, on the coast of Florida, 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.
