Surf Forecasting Guides

By Nick Peterson · Updated 2026-08-21 · ~1 min read
Start here: Every surf forecast is five numbers — period, height, direction, wind and tide. How to read a surf forecast explains them in order; How to read NOAA buoy data shows where the real-time numbers come from. The glossary defines each term, and the compare hub covers which app to use.

Reading the forecast

How to Read a Surf Forecast

Height, period, direction, wind and tide — what each number means, what "good" looks like, a worked example, and the ways forecasts mislead you. Step-by-step with links to every glossary term.

How to Read NOAA Buoy Data for Surfing

WVHT, DPD, APD, MWD, WSPD decoded; how to read a buoy in 30 seconds; flagship buoys for the West Coast, Hawaii, East Coast and Gulf; and where that data is already turned into a surf report.

Best Tide for Surfing

Low, mid or high? A table by break type — beach, point, reef, river mouth, jetty — plus incoming vs outgoing and how to find your own spot's tide window.
