Table - best surf conditions forecast for Montoya over the next 16 days.
Alright, Rusty here. Let's get into it.
First things first, it’s a bit of a slow start for Montoya. We’re looking at a pretty flat stretch for the first week or so, and honestly, the surf is mostly ordinary. The real action, if you can call it that, doesn't start to look interesting until the middle of the second week.
The water at Montoya is sitting at 52°, which is bang on average for this time of year, so no need to worry about thermals just yet.
The first real chance to get a wet suit on comes Monday morning, July 13th. The swell is a small 4 ft from the ESE, but the period is a short 7 seconds, so it’s going to be a bit weak and crumbly. The big win here is the wind: absolutely glassy, with a NE breeze at just 3 mph. That’s the kind of clean you dream about. The combined wave energy is moderate at 232 (moderate energy). It’s not going to be a standout by any means, but it will be the cleanest you’ll see for a while.
Tuesday morning, July 14th, also offers a chance. Swell is 4 ft from the ESE, with a slightly longer 10-second period, which means a bit more shape. The wind is a light cross-offshore from the NNE at 9 mph, keeping it tidy. Combined energy is still moderate at 233. It’s not a day to call in sick for, but it’s a solid enough surf.
After that, we hit a rough patch. From Wednesday, July 15th, through to Saturday, July 25th, the conditions are mostly poor – either choppy, cross-shore, or just onshore slop. There’s a day on Wednesday morning, July 22nd, with a clean cross-offshore wind, but the swell is a weak 3 ft. It’s a marginal window.
Now, the real standout. The best of the entire forecast is Saturday morning, July 25th. We’ve got a 3 ft swell from the East, with a 10-second period, and the wind is a clean offshore from the WNW at 9 mph. That’s going to be smooth and clean. The combined energy is strong at 360 (strong wave energy), so there’s some punch there. The swell direction is a little off from the optimum, but the offshore wind and clean conditions make this the best session on offer. Be aware it’s a Saturday, so the crowds are likely to be there.
The forecast after that, into Sunday July 26th, looks like it turns onshore and messy again.
So, to sum it up: early next week for a glassy, small day, but hold out for Saturday the 25th for the best of the bunch. It’s a long ways out, so keep an eye on it, but that’s the one that’s got my attention.
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.
