Table - best surf conditions forecast for Montoya over the next 16 days.
Alright folks, it’s Rusty here, and I’ve been staring at the charts for the Montoya area. I’ll be straight with you – this 16-day window is a mixed bag, with a whole lot of patience required to get the good stuff. There’s a long quiet spell at the start, so don’t get your hopes up for the first week.
The outlook kicks off with a real dud. Sunday, July 12th, is a write-off. We’ve got a weak, choppy 3ft ESE swell with a cross-on breeze, and combined energy is a measly 330 (moderate). The afternoon turns lumpy with a 5ft windswell from the South, but again, onshore and messy. Forget it.
Monday, July 13th, brings a little hope. The morning looks clean with a light offshore breeze, but the swell is a weak 3ft from the ESE with a short period of 7 seconds, and combined energy is only 222 (moderate). It’s surfable, but nothing to call home about. The water temp is sitting at 52°, which is bang on average for the time of year, so no surprises there.
The rest of the week through to the 19th is pretty ordinary. We’re looking at small waves, mostly under 3ft, with periods varying from 8 to 10 seconds. The wind is often cross-offshore or clean, which will keep the surface tidy, but the energy is low – combined energy mostly sits below 100 (weak). It’s the kind of small, clean surf that’s fine for a longboard or a foiler, but there’s no punch.
Now, the real standout comes in the second week. We have to wait until Tuesday, July 21st, for something to get excited about. That afternoon, the stars align. A clean 6ft swell from the East with a period of 7 seconds hits Montoya, and the combined energy jumps to a very strong 526! The wind is cross-offshore from the WNW, which should keep the waves clean. This is the best on offer, and with Montoya being a beach and point setup, that ESE swell direction is right on the money. The size is getting up there, so it’s more for the experienced crew – beginners might find it a bit much.
The following days, July 22nd to the 27th, are a mixed bag of smaller, cleaner swells (3ft to 5ft) with moderate energy, but the wind is often a problem. There’s a period of strong onshore winds from the 23rd to the 25th that makes things messy, but we do get a return to clean conditions from the 26th onwards with a light offshore breeze.
So, if you’re waiting for a wave, circle Tuesday, July 21st on the calendar. That’s the one to aim for. The rest is a waiting game.

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.
