The Lowdown
Right, let’s talk about Montoya. It’s a beach and point setup, so it’s got a bit of character. The water’s sitting about average for this time of year, nothing weird.
For the next few days, honestly, it’s pretty grim. Thursday and Friday are a write-off – tiny, weak, messy, with cross-shore chop. The wind is all wrong, and the swell’s just not there. We’re looking at combined energy in the low double digits, like 23 on Friday morning. That’s barely a ripple.
Then we get a bit of a lift on Saturday the 1st of August. The wind swings to a moderate offshore from the WNW, cleaning things up nicely. Swell comes in from the east at 4ft, with a 10-second period, giving us moderate energy (251). It’s not huge, but it’ll be the first decent look. The crowd factor is “sometimes” here, so expect some company. Still, Saturday morning is the best bet in this first week.
Sunday and Monday are back to poor cross-shore conditions, with small, weak swell. Monday the 3rd of August has a morning that’s marginal—clean enough, with a 3ft SSE swell and 11-second period, but the energy is moderate (309). It’s a maybe, not a must.
The next real standout doesn’t come until Sunday the 9th of August. That morning, the wind goes glassy – dead calm. Swell is 4ft from the SSE, 10-second period, giving us moderate energy (278). That’s the cleanest, most inviting surf of the whole stretch. The point will handle that nicely, and the beach will be peeling. That’s your best session.
Looking further out to Tuesday the 11th of August, the swell jumps up to 6ft from the SSE, with a 14-second period. That’s a long-period groundswell, with strong energy (1303). The wind is a cross-offshore, keeping it clean. But 6ft is getting into the expert zone, especially with that long period – it’ll be powerful and maybe a bit too straight for the beach, but the point could be firing. Keep an eye on it, but it’s a long way out.
After that, things drop back into poor, onshore mush. The 14th of August is a rain-soaked write-off.
So, the pick of the fortnight is without doubt Sunday the 9th of August, morning session. Glassy, clean, waist-to-chest high. The backup is Saturday the 1st of August, morning, with that offshore wind. Both are worth the paddle.

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.
