Hourly beach forecasts for Rio de Janeiro Coast. Check breaking surf, swell, wind and forecast confidence before planning your session.

BEHIND YOUR FORECAST

How this rating is built

—/100—

The beach’s wave-size profile provides the base. Period, wind, tide and chop adjust it; the forecasting engine then applies its caps and rounding.

Swell direction is already reflected in the beach’s estimated breaking surf. Forecast confidence is a separate measure from surf quality.

From the beach

Times use UK / Ireland local time. No photos, comments or precise personal location are collected. Guest and signed-in reports have the same moderation policy and no automatic algorithm influence.

Choose your surf alert

Uses your account’s saved surf profile. Emails always use metres and knots and show their forecast timestamps. Your profile is a preference, not a safety test.

Check the beach cameras

Known public camera pages from our curated registry. Availability and access can change; some providers require a subscription. Nearby cameras may show a different beach. Links open the provider’s site; BestSwell does not rebroadcast feeds.

Wind & swell at the coast

North-up map. Arrows show travel towards; compass values state where wind or swell comes from. Swell uses primary swell direction where saved, otherwise total wave direction, clearly labelled. Satellite images are a coastline reference, not live surf imagery. No beach-scale rip currents or hazards are inferred.
