How to know if the beach is good today

Why “is the beach good today?” is different from city weather

Your phone’s weather app shows the nearest town, not the shoreline. Beaches can be windy when inland is calm, or have bigger surf than the regional forecast suggests. Tides change how much dry sand you have hour by hour. Water temperature lags air temperature by days. To answer whether the beach is good today, you need beach-level wind, waves, water temp, sky, UV, and tide times in one place — then a clear summary you can trust before you load the car.

Wind — the biggest comfort factor

Onshore wind above 15–20 mph often means sand in your face, choppy surf, and harder swimming. Light winds (under 10 mph) usually feel best for a relaxed beach day. Our app reads NOAA wind speed and direction for each beach location.

Waves and surf height

Small waves (around 1–3 ft) suit most families and casual swimming. Larger surf can be great for experienced surfers but rough for kids. We use Open-Meteo marine wave height at each beach coordinate, so two beaches a few miles apart can score differently.

Water temperature

Gulf and Atlantic beaches vary by season: spring water can feel cool in the 60s°F while summer often reaches the 80s°F. We prefer CO-OPS station readings when available; otherwise we estimate from marine models. Too cold or unusually hot water lowers the comfort score.

Tides and timing your visit

Low tide exposes more sand and tide pools; high tide can shrink the dry beach. Neither is automatically good or bad — it depends what you want. Check today’s high and low tide times on each beach page before you pack the car.

UV and sun safety

A high UV index means faster sunburn even on cloudy days. Reapply sunscreen every two hours, seek shade mid-day, and bring hats for kids. Moderate UV still scores well for a beach day; extreme UV nudges the overall score down to remind you to plan shade.

Algae and red tide

We estimate algae risk from calm water, heat, humidity, and forecast text — not from a dedicated HAB satellite feed yet. If local officials post a red-tide or bacteria advisory, follow that over any app score. When in doubt, skip swimming.

The beach score (0–10)

On each beach page we show a weighted score built from eight factors: wind, waves, sky, air and water temperature, UV, inferred water clarity, and algae risk. Weights are fixed in our rubric so scores are comparable beach to beach on the same day. Open any beach to see the full breakdown — not a mystery number.

Frequently asked questions

How do I know if the beach is good today?

Check wind speed, wave height, water temperature, UV index, sky conditions, and tide times together. Is the beach good today? scores nearby beaches from live NOAA weather, CO-OPS tide and water-temperature stations, and Open-Meteo marine data so you get one number plus a breakdown before you drive to the shore.

What makes a beach score high or low?

Our rubric weights surf and wind (calmer is usually better for swimming), air and water temperature comfort, sky conditions, UV exposure, inferred water clarity, and algae risk from wind and wave patterns. Scores change through the day as forecasts update — they are not a fixed rating for every beach.

Is the water safe to swim today?

We show inferred water quality and algae risk from environmental signals, not lab-tested bacteria counts. Always follow local health department advisories, lifeguard flags, and red-tide bulletins. Use our score as one input, not the only safety check.

Do you cover beaches near me?

Yes. Enable location on the map view and we discover real beaches within about 50 miles using Mapbox and OpenStreetMap, then pull live conditions for each spot. Distance from you is shown on cards and on the map.

Where does your beach weather data come from?

Air temperature, wind, and sky conditions come from NOAA National Weather Service forecasts. Near-shore water temperature and tides use NOAA CO-OPS when a station is nearby. Wave height and UV index come from Open-Meteo. No signup required for basic conditions.
