Wind Types and What They Mean
Blows from land out to sea. Grooms wave faces, holds them up longer, and creates the clean conditions surfers love. Morning sessions often have the best offshore winds.
Flat, mirror-like ocean surface. Waves are clean and unaffected by wind. Often occurs at dawn or dusk. Many of the best sessions happen in glassy conditions.
Blows along the beach parallel to the shoreline. Creates some chop but not as destructive as onshore. Can be surfable depending on strength.
Blows from sea toward land. Chops up the wave face, causes early breaking, and makes paddling out harder. Generally poor surfing conditions.
How to Check Wind Before Surfing
- →Stand on the beach facing the ocean: If wind hits your face = onshore (bad). If wind hits your back = offshore (good).
- →Use a surf forecast app: Surfline, Magic Seaweed, or Windy show wind speed and direction for your specific beach.
- →Watch the water surface: Choppy, textured water = onshore wind. Smooth, glassy water = offshore or no wind.
- →Look at flags and trees: Flags and palm trees pointing toward shore = offshore wind. Pointing away from shore = onshore.
Frequently Asked Questions
What is offshore wind in surfing?
Offshore wind blows from land out to sea. It grooms wave faces and creates clean, glassy conditions — what surfers want.
What is onshore wind in surfing?
Onshore wind blows from sea toward shore. It creates choppy, lumpy wave faces and causes waves to close out — poor surfing conditions.
What is the best wind for surfing?
Light offshore wind (5-15 mph) or no wind (glassy conditions). Onshore wind is the worst for wave quality.
How do I know what the wind is doing before I paddle out?
Check a surf forecast app (Surfline, Windy, Magic Seaweed) that shows wind direction. You can also stand on the beach and feel which direction the wind comes from — if it is blowing into your face from the ocean, that is onshore.
Why is early morning often better for surfing?
Wind patterns often shift overnight. In many coastal areas, mornings are calm or have light offshore winds before sea breezes build onshore during the day.
