The Lowdown
Alright folks, Rusty here. Let's get into it for Montoya.
First up, a heads-up: the water temp here is sitting at 51°, which is about a degree cooler than usual for this time of year. Nothing too wild, just a little nippy for the first dip.
The next couple of weeks are looking pretty grim overall. We've got a long stretch of weak, messy wind swell with onshore winds ruining the shape. From Friday the 28th of August right through to the morning of Sunday the 6th of September, it's a real struggle. You’ll see little knee-high dribblers mixed in with cross-shore chop, and the combined wave energy is barely ticking over, often under 100 (weak) or just scraping into the low hundreds. Not worth paddling out for.
Now, the spark of life shows up way out in the forecast. On Sunday the 6th of September, things get interesting. The morning sees a solid 6 ft swell start to roll in from the SSE, with a long 14-second period. The combined energy jumps to 1204 (strong to very strong wave energy). The wind is still messy cross-shore in the morning, making it marginal, but the afternoon is where it's at. The wind swings NW, going offshore and light, grooming that 6 ft SSE groundswell (13-second period) into clean lines. This is the standout session, best for experienced surfers wanting some power. The wave energy peaks at 1211.
Monday the 7th of September holds onto that size, with 6 ft in the morning, but it gets hammered by a fresh 19 mph cross-shore SW wind. By Tuesday the 8th of September, it drops to 4 ft and the wind improves to a cleaner cross-off, but the magic is gone.
Then, on Saturday the 12th of September, we get a late bloomer. A 6 ft swell from the east pushes in, but the period is a short 7 seconds – wind swell. The morning has decent clean conditions with a cross-off WSW breeze, giving waves that are “expect good surf.” Energy is moderate at 385. It won't be as polished as the 6th, but it’s another shot if you missed the main event.
If you're a beginner, be careful – those 6 ft to 6 ft days on the 6th and 7th are big and powerful. The best call of the whole 16-day window is without a doubt Sunday afternoon, the 6th of September.
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.
