Shaka Surf: Surf Forecast

Shaka Surf is a free, open surf-forecast app for surf breaks all over the world. No subscription. No paywall. No account required.

Spin a live 3-D globe, tap any glowing break, and instantly see:
• Current swell height, direction and period
• Wind speed and direction — with an offshore/onshore quality rating
• A transparent 0–10 surf quality score broken down by factor
• 10-day hourly forecast with a rated "best window" highlighted
• NOAA tide curve for the nearest station
• Live NDBC buoy observations (US breaks)
• Free public webcam streams where available

SURF QUALITY, MADE TRANSPARENT
Every break shows a live quality score built from swell energy, wave period, swell
direction, tide stage and a wind-direction penalty calibrated to the spot's offshore
heading. Each factor is shown separately — no magic black box.

GLOBAL COVERAGE
More than 6,700 surf breaks worldwide: every coast, every country. Famous big-wave
spots, local beach breaks, reef breaks, point breaks and river mouths. Zoom into any
coastline and the pins appear, coloured live by how good it is right now.
