Frequently Asked Questions

What kind of wave is Publics?

Publics is a reef break in South Shore, Oahu, USA, that mostly breaks left over a reef bottom. On its biggest days it can hold faces of around 2.5m. It's one of the more consistent spots around (7/10).

What swell works best at Publics?

Publics picks up swell from the SSE round to the SW, and it's best when it's coming straight out of the S. It starts working at around 0.9m and handles up to about 1.8m, with the sweet spot around 1.3 to 1.6m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

What wind is offshore at Publics?

A NNE wind is dead offshore at Publics, and anything from the NNW round to the E keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

What tide is best at Publics?

Publics is at its best around the mid to high tide. Below 0.3m it gets dangerously shallow.

When is the best time of year to surf Publics?

The most reliable run of swell at Publics comes May to Sep. There's a second window in Apr and Oct too. May-Sep. One of the longest lefts in Honolulu. Low tide dangerous over sharp live coral.

How cold is the water at Publics?

The water at Publics averages around 26°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.

Is Publics good for beginners?

It's more of an intermediate wave, rated 5/10 for difficulty, so newer surfers are best off sticking to the smaller days. It gets busy (crowd 9/10), so mind the pecking order. Sharp shallow live coral. Softer on higher tide, hollower on low. Always crowded.

How do I get to Publics?

The nearest airport on our list is HNL, then it's roughly a 15-minute drive. Beach access near Diamond Head.

What other surf spots are near Publics?

The closest breaks we track are Queen's (1.0 km), Three's (1.1 km) and Canoes (1.3 km), handy when Publics isn't working. We track 6 spots around South Shore, Oahu in total.
