The Lowdown
Alright folks, Rusty here. We've got a bit of a mixed bag on our hands for the Montoya area. We're starting off with a blank run, so don't bother waxing up just yet. The first decent look at the ocean won't come until Sunday the 16th, so there's a bit of a wait.
The first sign of life is Sunday morning, August 16th. We're looking at a small, clean swell with a light north wind, making it a cross-off breeze. The waves will be around 4ft from the east, and the light wind will keep things tidy. It's not big, but it's a chance to get wet. The water temp is sitting at 52°, which is about average for this time of year, so you won't need a steamer just yet.
After that little window, it all goes quiet again. We've got a long dry spell with messy winds and poor conditions. The wind is all over the place, mostly onshore, and the swell energy drops right off. We're looking at combined energy levels as low as 28 and 32 later in the week, which is about as weak as it gets. This stretch runs from Sunday afternoon all the way through to Friday the 22nd.
Now, if you can hold out, Saturday the 22nd of August is where it gets interesting. We've got a proper pulse of south swell arriving, with 6ft waves from the south and a period of 12 seconds. That's some real groundswell energy, with combined energy hitting 952 – a solid, moderate push. The wind swings west at 22 mph, but it's a cross-off breeze, keeping the surface clean. This is a standout for the more experienced crew.
Sunday the 23rd looks even bigger, with 10ft south swell, but it's crossed up with a 12 mph cross-onshore wind. That kind of size and direction at a beach and point setup is going to be a mess. Honestly, with that wind, it might be more of a kite day than a paddle day.
Looking further out to the start of the second week, Saturday the 29th of August is another promising window. A clean 6ft swell from the south-southeast, with a 6 mph west-southwest breeze keeping the surface glassy. Combined energy is a decent 656. It's a long way out, so don't book the trip just yet, but it's one to keep an eye on.
All in all, the real gems are the Sunday the 16th morning for a small clean one, and Saturday the 22nd for some proper size and shape. The rest of the period is a lot of waiting for the wind to play ball.
Stay frothy,
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.
