The Lowdown

Alright, surfers, grab a coffee, this one’s a bit of a tough read. Rusty here, and I’ve got to be straight with you—the outlook for Montoya is mostly a story of waiting. We’re looking at a long stretch of poor conditions, so don't be in a rush to paddle out. It’s a beach and point break, exposed to the south, and it needs the stars to align a bit more than it does across this 16-day window.

The core issue is a persistent onshore or cross-onshore wind. For the first week, from Monday the 10th of August right through to about Saturday the 16th, the wind just won't cooperate. We get moderate cross-onshore breezes, mostly from the SSE and ESE, mixing things up with high energy swells that don't translate into quality. The combined swell energy is significant, sometimes reaching 512, 851, or even 1168 (moderate to strong energy), but the wind is just tearing it apart. The wave comment is poor, and the scores reflect that. You'll be fighting chop and bump all session. Not the vibe.

There’s a tiny window of hope on Monday the 17th of August in the afternoon. The wind swings to the WSW, going cross-offshore, and the setup cleans right up. Swell should be around 5 ft from the SSW. The period is only 6 seconds though, so it’ll be a short, lumpy little windswell. The combined energy is a moderate 231. It's surfable, but it’s nothing to write home about. I’d call it a marginal session for someone desperate to get wet.

Tuesday the 18th of August morning is a real teaser. The wind goes completely glassy (0 mph) at dawn, and there’s a tiny, clean swell. The wave period is a short 7 seconds, and the combined energy is just 108 (weak), so you’re looking at small, soft waves. The comment says "surfable waves but very ordinary conditions"—that’s about right. A super-small, glassy morning for a longboard. The score is a 1 out of 10, so keep your expectations at zero.

After that, the forecast falls off a cliff again. Strong, messy cross-onshore winds return from the 20th of August onwards, with a couple of days seeing strong breeze and lumpy surf. The combined energies are more moderate, but the quality is shot.

The one true standout, if you can call it that, is that very small, glassy window on the morning of Tuesday the 18th. For a longboarder who just wants to feel the water, it might be the cleanest wave of the whole run. But anyone looking for size or power will be frustrated. There’s nothing for beginners here at any point—the few days with height are blown out, and the clean days are too tiny. For experts, there’s no real juice on offer.

This is a tough two-week forecast for Montoya. The wind is the enemy, and it rarely lets up. We get tiny windows, but consistency is nil. It’s a blank run for the most part, which is a shame for a spot that can fire.

Stay patient, mates. Check in next week; forecasts can change.
Rusty.

Information about the Montoya Surf forecast

The above surf forecast table for Montoya provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Montoya can be found by selecting the local surf guide option on the grey menu. Our Montoya surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Montoya) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Montoya may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
