What is offshore wind?

Offshore wind blows FROM the land TOWARD the ocean. It pushes against incoming wave faces, holding them up so they stand cleanly before breaking. Offshore wind grooms wave shape — it is the surfer's favorite condition. Many coastal areas get offshore wind around dawn before the sea breeze develops.

What is onshore wind?

Onshore wind blows FROM the ocean TOWARD the land. It blows waves apart from behind, making them break early, mushy, and disorganized. The water surface becomes choppy with whitecaps. Onshores are called "blown out" conditions — most surfers stay home.

Why is dawn the best time to surf?

Many coastal areas have a daily wind cycle: light overnight winds (sometimes weak offshore from cooler land), a morning calm, then a daytime sea breeze building onshore by midday. The dawn offshore window is when wave faces are smoothest. By 11am the sea breeze typically picks up and conditions degrade — hence "dawn patrol."
