The Lowdown
Alright, let’s get into it. This is Rusty, and I’m lookin’ at the next couple of weeks for Montoya.
First off, I gotta be straight with you: the next several days are a bit of a write-off. We’re talkin’ a long stretch of poor surf conditions from Monday, the 24th of August, all the way through to the end of the month. The water temperature is sittin’ about average for this time of year, so no surprises there.
Monday morning at Montoya (beach and point) has a 6ft swell from the SSE, but that cross-on wind from the south at 9 mph is messin’ it up. The combined wave energy is moderate (905), but the conditions are choppy and onshore. It’s a no-go. Monday afternoon, Tuesday, and Wednesday all offer similar stories – waist-high-ish swell, but the wind is just wrong, usually cross or cross-on, leadin’ to marginal or poor surf. The energy drops right off, too. By the 27th and 28th, we’re down to dribbly 2ft to 3ft waves with almost no energy (188 down to 159). It’s a tough stretch.
Then we hit a real blank spot. From the 29th of August through to the 6th of September, it’s pretty much all poor surf. The swell is tiny, mostly under 3ft, and the periods are short – think 5 to 7 seconds. The combined energy is weak, barely crackin’ 100 (like 63, 65, 34). A lot of those days have onshore wind, just no power in the water. Not worth paddlin’ out for.
Now, there’s a little flicker of life on the 1st of September. Tuesday morning brings a 5ft swell from the SW, but it’s a short period of 6 seconds – that’s windswell, not groundswell. The wind is offshore from the WNW at 12 mph, so the surface will be clean, but the wave quality is just “ordinary”. The energy is low (164). It’s a session for the die-hard, but not really a standout.
The real highlight, the only one I’d seriously point you at, is the 8th of September, Tuesday morning. We’ve got a 4ft swell from the east, with a period of 8 seconds. A light offshore wind from the NNE at 6 mph will have it glassy. The wave energy is moderate (217) and the forecast says “expect good surf conditions.” This is the best on offer. The wind is clean, the swell is rideable for intermediates, and it’s not too big. Crowds are “sometimes” a thing at Montoya, so you might have a few others out, but it’s the best bet in this 16-day window.
Everything after that in the second week is small, short-period, and mostly poor. The 7th of September has a bit of size (5ft) but the period is 8 seconds and the wind is cross-shore, so it’s messy.
So, to sum it up: a long, slow start, then a solid chance on the 8th of September. That’s the one to circle.

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.
