The Lowdown
G’day, Rusty here. Let’s talk about Montoya. It’s been flat as a pancake, and the first real chance to get a surf in is Thursday, September 3rd, but it’s nothing to write home about. The first week and a half are a real grind, with tiny, weak swell and a lot of messy wind.
The one day that stands out, the one I’m actually excited about, is Sunday, September 13th. That’s the day. We’ve got a solid S swell running at 4 to 4 ft, with a period of 12 to 13 seconds – that’s proper groundswell, with real energy. The combined energy is a strong 540 to 584, so there’s plenty of power. And the wind? Monday morning it’s a clean offshore from the NW, and by the afternoon it’s a light, clean cross-offshore from the WNW. That’s gonna make for some beautiful, glassy faces. The water is about 55°F, which is a touch warmer than usual for this time of year, so that’s a bonus. Montoya is a beach and point break, and with that long-period swell, the point is where you’ll want to be for the best lines. The 4 ft is a solid size, not too heavy for most, but it’ll have some push. Expect some company, though – crowds are possible here.
Before that, there’s a couple of other days that might be a last resort. Thursday, September 10th, has a clean offshore wind from the NNW in the afternoon, but the swell is only 3 ft from the E and the energy is weak at 154. It’s rideable, but it’s a real “meh” session. Then Monday, September 14th, has a moderate offshore wind from the WNW in the morning with 3 ft of SSE swell, but again, it’s nothing special.
The rest of the time is a total write-off – strong winds, choppy mess, and tiny swell. The gap from the start of the month to that Sunday the 13th is a long, dry spell of nearly two weeks with no real action. But when that Sunday shows up, it’ll be a cracker.
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.
