Surfing Banyans: The Complete Guide

Banyans is a reef break located in Kona Coast, Big Island, USA (HI), offering both lefts and rights along North America's diverse surf scene. Banyans is the Big Island's best wave—an A-frame reef break that catches both W/NW swells in winter and S swells in summer, making it one of Hawaii's most versatile spots. Rated as intermediate difficulty with moderately crowded conditions, this reef break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is W (270°), with workable conditions from SSW to WNW (200°–300°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Banyans needs a minimum of 0.9m / 3ft to start working and handles swells up to 2.4m / 8ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 10 seconds, with 14 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Secondary Swell: Catches S swells in summer in addition to NW swells in winter.

Wind: True offshore here blows from the E (80°). The full offshore range spans NNE to SE (30°–130°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at mid tide.

When to Go

Primary Season: The prime window at Banyans runs November, December, January, February, March (Nov–Mar). This is when swell consistency and direction align most reliably with the break.

Secondary Season: A secondary window opens May, June, July, August, September (May–Sep). While not as consistent, patient surfers can still score quality sessions during this period.

Season Notes: Year-round. S swells in summer, NW in winter. Shane Dorian's home break.
