About
Thermopylae is a rare, exposed left-hand point/reef break near the Mouille Point shipwreck remains. The wave breaks over a rocky ledge/reef with shipwreck influence on the seabed, creating a technical, high-performance surf that can deliver long wall sections along the rock shelf. The spot is described as fickle and best when a significant southwest swell wraps in properly and the timing is right—high tide is consistently highlighted as the best period. Offshore easterly winds (including East or Southeast offshore flow) are noted as the conditions that best glass the wave, helping it line up cleanly for a more organized ride. Hazards are a major theme. Expect sharp rocks, shipwreck debris, dense kelp, and sea urchins around the entry/takeoff area. In addition, pollution risk is specifically called out: an E-coli zone is associated with nearby sewage outlets, and there are practical warnings to avoid surfing after heavy rainfall due to storm-drain/urban runoff contamination. Because it’s isolated and works only on specific swell windows, crowding is reported as low-profile, with long lulls between swells unless a larger swell system is running. The takeoff can be hairy depending on swell size and tide, so the spot is best approached with intermediate-to-advanced experience.
- Exposed left-hand point/reef break near the Thermopylae shipwreck remains
- Long wall sections along the rock shelf
- Best at high tide with southwest swells and offshore easterly winds
- Low crowd levels compared with nearby mainstream surf
- Rare exposed left-hand point/reef break with long wall sections
- Best conditions are well-defined: high tide with southwest swell and offshore easterly winds
- Generally low crowd levels due to its isolated and challenging nature
- Fickle and technical: needs the right swell direction and sufficient size to wrap in
- Hazardous environment with rocks/reef and shipwreck debris, plus dense kelp forests
- Water contamination risk is flagged around nearby sewage outlets (E-coli zone); avoid after heavy rainfall
- Long lulls can occur unless a really big swell is running

By sport
What to expect for each.
An exposed left-hand point/reef break breaking over the remains of the Thermopylae shipwreck near Mouille Point. It is technical and fickle, requiring a significant swell to wrap in.
- Wave Direction
- Left
- Optimal Swell
- SW
- Swell Height
- 2–4.5 m
- Optimal Tide
- High — Best at high tide.
- Shelter
- Exposed — Exposed break.
- Wind Effect
- Best with offshore easterly winds glassing the wave (also described as best with offshore East or Southeast winds).
- Bigger Swell
- Holds size; requires a 10'+ swell unless conditions are more favorable (e.g., westerly/northwesterly). Another source notes it becomes more defined but heavier on large swells.
- Wave Quality
- Good — Reported as good.
- Wave Power
- Moderate — Wave power is described as moderate in one source, and powerful in another; overall it is a performance-focused break.
- Wave Shape
- Peeling — Reported as peeling, with another source describing hollow sections as tide rises.
- Peel Speed
- Medium — Peel speed is reported as medium (with another description noting fast/hollow performance as conditions/tide change).
- Ride Length
- Medium — Can produce fast, walling sections along the rock shelf; long walls are also specifically noted.
- Typical Ride Length
- 50–100 m
- Ride Length Details
- Really long walls as the wave travels along the rock shelf; can offer fast, walling sections that become hollow as the tide rises.
