Surfing St Clair: The Complete Guide

St Clair is a sandy-bottom beach break located in Dunedin, New Zealand, offering a right-hander along New Zealand's coastline. St Clair is cold water surfing at its most rewarding—Dunedin's main beach break exposed to the roaring forties, where consistent southern swells meet dedicated locals in 5mm wetsuits and booties. Rated as intermediate difficulty with moderately crowded conditions, this beach break is a worthy destination for surfers looking beyond the usual suspects.

Best Conditions

Swell Direction: The ideal swell direction is S (180°), with workable conditions from SSE to SW (150°–220°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: St Clair needs a minimum of 0.6m / 2ft to start working and handles swells up to 2.5m / 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.

Wind: True offshore here blows from the N (0°). The full offshore range spans NW to NE (320°–40°). 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 all tides. Optimal tide range is 0.4m–1.6m.

When to Go

Primary Season: The prime window at St Clair runs March, April, May, June, July, August, September, October (Mar–Oct). This is when swell consistency and direction align most reliably with the break.

Secondary Season: A secondary window opens November, December, January, February (Nov–Feb). While not as consistent, patient surfers can still score quality sessions during this period.

Season Notes: Consistent S swells. Medium-high consistency year-round.
