Coasti answers one question before you pack the car: is today a beach day?
Open the app and get a clear verdict for your beach, not a wall of numbers. Coasti reads the beach flag, wind, surf, tides, UV, water quality and active weather alerts, then tells you plainly whether it is a good day to go and when the best window is.
WHAT YOU GET
A plain-language verdict for beaches, backed by official sources
Beach flag status, with storm warnings escalated automatically
Surf, wind, water temperature, tides, and UV at a glance
A best-window line so you can time your trip
A Tomorrow view for planning ahead
An interactive map with flag-colored beach markers
Search with filters for parking, dog friendly, lifeguards, restrooms, and more
FROM BEACHGOERS Real people at the beach report what they see: jellyfish, rip currents, crowds, water clarity, wildlife. Reports are advisory and never change the official verdict.
SAVE YOUR BEACHES Sign in to save favorites and set a home beach. Get a morning email with your beach's verdict, storm alerts when severe weather hits, and a push notification the moment a saved beach's flag changes color.
Coasti pulls from official government sources including NOAA and the National Weather Service, along with local beach flag programs, refreshed around the clock.
The coast is calling. Coasti knows if it is clear.
The radar now moves. Open the map and watch the last 50 minutes of storm motion, so you can tell whether a storm is heading for your beach or already on its way out. A small dial shows where you are in the loop.
Two new guides join Settings: Lightning at the beach, with a live list of beaches that have storms nearby right now, and Manatee season, with live water temperatures from NOAA stations.
If location is off for Coasti, the map's locate button now explains how to turn it back on. The map also always fits the screen, with no scrolling.
