The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Montoya stretch over the next couple of weeks.
To be straight with you, the first few days are a bit of a write-off. We’ve got a persistent run of small, weak swell and mostly onshore or cross-onshore winds that are just making a mess of things. The wait is worth it though, because the real standout is hidden in the second week.
The Overall Picture
We’re looking at a long, slow start. From Friday 17th July right through to the middle of the following week, conditions are pretty grim. The swell is tiny and the wind is a problem. It’s not until Sunday 19th July that we see a pulse of energy, but even then, the timing is tricky.
The First Standout
If you’ve got patience, circle Sunday 19th July afternoon. That’s our first real highlight. Montoya picks up a solid 7ft swell from the S, with a short period of 7 seconds. The combined energy is moderate at 560. Now, the period is short, so it’ll be a bit lumpy and on the punchy side, but the wind is glassy and that’s a huge win. The water temp is sitting at 52°F, which is about average for this time of year, so don't forget your wetsuit. This is the best of the first week, but it’s a one-off. The rest of the week after that is just back to slop.
The True Standout – The Second Week Gem
The real magic is looking like Saturday 25th July afternoon. The forecast is a bit further out, so it’s promising but not locked in yet. We’ve got a 4ft swell from the S, but this time the period is a much nicer 10 seconds, giving it some proper groundswell energy – the combined energy is strong at 335. The wind is glassy, which is an absolute treat. Montoya is a beach and point setup, and with this longer period, it might actually line up nicely on the point. This is the session to aim for. It’s clean, well-shaped, and a little bit of size. The swell direction is S, which is bang on the optimum for this spot.
The Rest of the Window
Beyond that, things get a bit messy again. The morning of Sunday 26th July is a write-off with cross-onshore winds. There are a few marginal windows in the last week of July and into August, but nothing that can compete with that Saturday afternoon session. There’s a stretch from Friday 31st July through to Saturday 1st August that’s looking like a full blank run with poor conditions.
The Verdict
If you’re a beginner, the 7ft on the 19th is getting a bit punchy, so watch yourself. The 4ft on the 25th is a much friendlier size. For experts, the shorter period on the 19th might be a bit of a close-out, but the 25th is where it’s at.
Stay patient, watch the wind, and be ready for that Saturday afternoon.
Rusty.

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.
