Mompiche Surf Forecast and Surf Report

Alright, let me tell you – it’s Rusty. The long-range picture for Mompiche is a bit of a struggle this time around. We've got a solid 16-day window, but honestly, the first half is looking pretty average at best, with only a few scattered moments where it might come together. There’s a long quiet patch from the afternoon of the 8th through to the 21st where the surf is consistently poor or too small to get excited about. Let's break it down.

We start off with some small, inconsistent swell on the 6th (Sunday). Swell is 3 ft from the SW, with a period of 14 seconds – that's a bit of groundswell, which is usually better for a point break like Mompiche. The combined energy is ticking along at (415). The water is sitting at 81°, and that’s a notable 4° warmer than normal for this time of year, so it’s a bit of a bath out there. The morning has a cross-off wind from the SSW at 12 mph, so it’s clean, but the score suggests it’s marginal. The afternoon turns to a cross-shore, making it a bit choppy.

Monday the 7th is similar, with the swell dropping to 3 ft, still SW, and the period 13 seconds. The morning is clean with a cross-off, but the afternoon gets cross-on and choppy – poor. Tuesday the 8th is smaller again (2 ft and 2 ft), with a light cross-shore in the morning and a chop in the afternoon.

Now, there’s one day that perks up a bit. Wednesday the 9th (morning) is probably your best bet in the first week. Swell is only 2 ft, but it’s coming from the SW with a very long period of 19 seconds. That’s serious groundswell energy, and at a point break like Mompiche, it’ll wrap in nicely. The combined energy is moderate at (490), and the wind is a light cross-off from the SSW at 6 mph – super glassy and clean. It’s a standout for quality because of that wind and the long period, but don't expect big waves. The afternoon gets a moderate cross-shore and a bit of a chop.

Thursday the 10th sees a little jump in size to 4 ft in the morning (SW, 16 sec), with moderate combined energy (710), but the cross-shore wind keeps it from being perfect. It’s a marginal call.

From Friday the 11th onward, the trend is downward. We get a few mornings with clean conditions and cross-off winds (like the 11th morning and the 13th morning), but the swell is tiny – 3 ft down to 2 ft. The 13th morning has a 19-second period, but it’s only 1 ft, so it’s a tease.

The rest of the run, from the 14th (Monday) through to the 21st (Monday), is a real slog. Swell heights drop under 2 ft, often 1 ft, and the combined energy falls to weak two-digit values like (90) or (82). The wind is mostly cross-shore or cross-on, and the surf is assessed as poor. Honestly, it’s going to be flat or too weak to paddle for.

If there’s a highlight in this whole outlook, it’s Wednesday morning the 9th of September – it’s the only time where we get a clean, glassy morning, a long-period groundswell hitting a point break, and the water’s warm. It’s not big, but for quality, that’s it. The rest is a waiting game.

This whole stretch is a classic case of "wait for the next pulse." It rarely stays poor for long here, but right now, the models are showing a blank. Keep an eye on it, but don't hold your breath.

Rusty.
