The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Montoya over the next couple of weeks.
We’re kicking off Monday the 24th of August with a bit of a nothing burger. The first few days are a write-off – poor conditions, onshore winds, and the swell is all over the place. We’ve got a moderate 905 combined energy reading on Monday morning, but that’s wasted with cross-onshore wind and messy surf. Tuesday the 25th shows a glimmer of hope with some cleaner conditions, but the swell is only 4ft from the SSE and it’s not really hitting its straps.
The real standout comes mid-week. Wednesday the 26th of August, morning sees a solid 5ft SE groundswell with a very long period of 15 seconds, and the combined energy rockets up to 1111 – that’s strong stuff. The wind is cross-shore though, so it won’t be pristine, but there’s plenty of juice in the water. This is expert territory at that size, and the long period means the waves will have real shape and power, especially holding up on the point. Just keep in mind the NE wind will put a bit of a chop on the surface.
Thursday the 27th morning is the pick of the early run. The swell drops to 3ft from the SE with a period of 13 seconds, combined energy at 308 (moderate), but the wind turns cross-offshore from the north, and it’s clean. That’s a lovely window for intermediate surfers – not too big, but with enough period to push through. You’ll get some fun little runners on the point.
After that, we hit a massive gap. From Thursday afternoon right through to the end of August, it’s a total flat spell. Onshore winds, tiny weak swell, and energy readings barely breaking 100. That’s a solid 4–5 day stretch with nothing worth paddling out for.
Things start to look up again on Monday the 31st of August. The morning offers a glassy 5ft swell from the east, period of 9 seconds, and combined energy at 356. The wind is glass – barely a breath – and the conditions will be clean as a whistle. The swell’s moderate in size, but that glassy surface is a major positive. This is the kind of morning you set the alarm for.
Tuesday the 1st of September is marginal at best, with onshore winds messing things up. But then Wednesday the 2nd of September afternoon brings another highlight: a clean 3ft ESE groundswell (period 11 seconds) with offshore NW wind. Combined energy is 288 – moderate but with that offshore breeze, the waves will be groomed and peeling nicely. This is a quality, fun-sized session for the intermediate crew.
The rest of the forecast into the second week is pretty bleak. Winds pick up again, swells drop off, and we’re looking at poor to marginal conditions all the way through to the 8th of September. There’s a brief cross-off window on the 5th of September, but the swell is only 4ft with a short period, and the energy’s not impressive.
Overall, the standout session is Wednesday the 26th of August morning – big, powerful, long-period swell, even if a bit bumpy. The second best is Monday the 31st of August morning for that glassy, clean goodness. The rest of the run is either poor or small.
So get on it while you can. This stretch has some classic moments, but you gotta pick your windows.
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.
