Troncones - surf spot statistics

Best Surf Season (November - February)

This is Troncones’ sweet spot. As the North Pacific winter pattern settles in, the trade wind inversion weakens, allowing frequent offshore breezes from the N-NE quadrant. Swell heights average a solid 1.2-1.3m with long-period groundswell (13-14s) sourced from distant Southern Ocean storms and the occasional North Pacific fetch that wraps into the SSW shore. The result? Powerful, clean lines that peel down the beach. December and January peak with over 50% ideal wind, making for consistent, rippable waves.

Fair Surf Season (March, April, October)

Transition months bring a trade-off. In March and October, you still get reliable pulses of SSW-SW swell, but the wind becomes a gamble. Offshore mornings are common, but afternoons see increasing onshore flow from the S-SW. April sees the swell ramp up (1.4m average) and periods lengthen, but ideal wind drops to 32% – meaning you’ll need to pick your windows carefully. These months are worth chasing if you time the morning offshore window or a post-frontal shift.

Low Surf Season (May - September)

The summer doldrums and hurricane season bring the largest swell of the year (1.5-1.7m average) with plenty of punch, but the wind is persistently onshore from the S-SW over 60% of the time. Dominant wind directions (SW, WSW) destroy the wave shape, making for choppy, bumpy conditions. While you might score a clean morning if a tropical storm passes far to the south and creates a window of offshore flow, most days are ruled by textured, subpar surf. The occasional hurricane swell can deliver XXL waves, but only for the brave and experienced – and only if the wind cooperates.

July: Peak Swell, Wind Relief Begins?

July shows a slight improvement in wind with ideal at 39%. Swell averages 1.5m with 13.5s periods. Dominant swell direction is SSW (62.6%) and S (29.6%), meaning plenty of swell energy. Winds are still mainly onshore but with a broader distribution: SE (9.7%), SSE (7.6%), and S (5.9%) bring some relief from the direct SW onshore. Offshore N-NE is around 20% combined. The mornings can be clean, and the waves are solid. This month offers a better chance of scoring without the harsh afternoon chop.
