Forecast guide

How our forecast works

A clear, spot-aware view of the ocean conditions that matter before you paddle out.

Open-Meteo provides a coarse-grid estimate, not a measurement at the break. Nearshore conditions can differ significantly, especially around beaches, reefs, and complex coastlines.

Data source

Marine and weather data comes from Open-Meteo, combining its marine forecast with local hourly weather conditions. Open-Meteo's free tier restricts commercial use; paid access may be required for ad-supported use. See Open-Meteo's terms for licensing and attribution requirements.

Hourly updates

The upstream marine and weather models provide hourly forecast points across the next seven days. Each spot page shows when its forecast was fetched.

Spot-aware ratings

Ratings compare swell and wind direction with each spot's preferred conditions.

How Epic, Good, Fair, and Poor are calculated

Each forecast point receives a score from four weighted factors: wave size (25%), swell period (15%), swell direction (35%), and wind quality (25%). Wind cleanliness is folded into the wind-quality factor rather than added as a fifth weight. Very small surf under 0.35 m (about 1.1 ft) is Poor, and it cannot receive an Epic rating.

Epic

Swell and wind are exceptionally aligned, with enough size and period to support quality surf.

Score 0.85 or higher, wind at 18 mph or less, wave size at least 0.75 m (about 2.5 ft), and period at least 8 seconds.

Good

Swell and wind are aligned, with workable wave size and period.

Score 0.65–0.84, wind at 22 mph or less, and wave size at least 0.5 m (about 1.6 ft).

Fair

Some swell, wind, size, or period conditions are outside the preferred range.

Score 0.25–0.64, with wind at 30 mph or less.

Poor

Wind or swell direction is unfavorable for this spot.

Wave height under 0.35 m (about 1.1 ft), wind above 30 mph, or swell and wind both poorly aligned with wind above 18 mph; isolated changes are smoothed unless they persist for two hours.

Forecasts are guidance, not a guarantee. Local observations, tide, hazards, and your own experience should always inform your decision to surf.
