Frequently Asked Questions

What kind of wave is Hull Bay?

Hull Bay is a reef break in St Thomas, US Virgin Islands, with peaks that run both left and right.

What swell works best at Hull Bay?

Hull Bay picks up swell from the NW round to the NNE, and it's best when it's coming straight out of the N. It starts working at around 0.8m and handles up to about 2.5m, with the sweet spot around 1.6 to 2.1m. 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 Hull Bay?

A SE wind is dead offshore at Hull Bay, and anything from the E round to the S keeps it clean. The morning is typically the best window, roughly 6am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.

What tide is best at Hull Bay?

Hull Bay is at its best around mid tide, roughly 0.6m to 1.5m on the local chart.

When is the best time of year to surf Hull Bay?

The most reliable run of swell at Hull Bay comes Nov to Mar. There's a second window in Sep to Oct too. Best in USVI. Needs solid N swell.

How cold is the water at Hull Bay?

The water at Hull Bay averages around 27°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.

Is Hull Bay 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. The lineup is usually quiet (crowd 3/10). Best in USVI. Needs solid N swell.
