The Lowdown
Alright, folks, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty bleak for a proper paddle. We’ve got a long stretch of small, messy, and wind-blown conditions ahead, so temper those expectations. It’s not a total write-off, but you’re going to have to pick your moments carefully.
The first real chance for a surf comes this Tuesday afternoon the 15th. A small 4ft SW swell rolls in, but it’s coming with a fresh 19 mph cross-onshore wind. It’s going to be lumpy and uninviting. That sets the tone for the next several days. Through Wednesday and Thursday, the swell drops and shifts, but the wind stays onshore or cross-shore, keeping everything small and junky. We’re looking at a real dry spell for any kind of quality.
There’s a bit of a tease on the morning of Monday the 21st. The swell is only 3ft from the east, but we get a clean, gentle offshore wind from the WNW. It’s surfable, but honestly, it’s pretty ordinary. You might get a few grovelly ones if you’re desperate. The window is small, and the energy is weak, with the combined swell energy at 134.
The next notable window doesn’t come until the following week. On the morning of Wednesday the 23rd, things start to look up. We’ve got a 4ft SSE groundswell with a solid 11-second period. The wind is a light cross-offshore from the NNE, which should keep the face of Montoya reasonably clean. This is probably the best chance we’ve got in this whole stretch. The combined energy jumps up to a moderate 313, which is a big step up from what we’ve seen. It won’t be epic, but it should be clean and have a bit of push to it.
The morning of Thursday the 24th is worth mentioning too. The swell drops slightly to 3ft, but the period stretches out to 12 seconds, and we get a moderate offshore from the WNW. Expect clean, lined-up waves, though the size is on the smaller side. The combined energy is 242, so there’s still some life in the water.
After that, it’s a slide back into mediocrity. A new SW swell builds on the 26th and peaks on the 27th, reaching a solid 7ft. But it’s arriving with a strong ESE wind, creating fresh, cross-onshore, lumpy conditions. The energy reading is a massive 1494, but it’s all going to be blown-out and messy. This is a case where the setup looks way more interesting for a kite surfer than for someone on a paddleboard. It’s expert-only at best, and even then, it’s going to be a battle.
The last days of the month just continue the trend of onshore winds and poor quality. There’s no shortage of swell at times, but the wind just won’t cooperate. We have to be honest: there are no true standout days here. The best surfing will be the clean, small days around Wednesday and Thursday next week on the incoming south swell. It’s a waiting game, but that’s how it goes sometimes.
Rusty, out.

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.
