The Lowdown
G’day, Rusty here. Looks like we’re in for a bit of a slow start at Montoya (beach and point), with hardly any surf worth paddling out for over the first few days. The pattern is pretty flat, and this spot is fairly consistent usually, so this stretch of quiet water is a bit of a bummer, but it won’t last forever. The first real chance of a decent wave doesn’t show up until Monday, September 14, and even then it’s just ordinary conditions with a small 3ft SSE swell and light cross-offshore wind. No standout there.
The real standout comes on Wednesday, September 16, and this one’s got a bit of heart. Early morning you’ve got glassy conditions with zero wind—absolutely clean—and a solid 5ft swell from the SSE wrapping in with a 10-second period. The combined energy is pumping hard (511), which is a strong push of water, and for a beach-and-point setup, that SSE swell direction lines up nicely with the optimum S direction. This is your best bet in the whole outlook: the morning will be smooth, the sets will have some punch, and the crowds are only sometimes an issue, so you might get a few waves to yourself. Water temp is about average for this time of year, so nothing unusual there.
After that, Thursday September 17 holds some fun waves in the afternoon: 3ft SSE swell with a 12-second period, clean cross-offshore wind, and good surf conditions. Not a standout, but a solid session.
The second week goes quieter again. Saturday September 19 has a tiny 0.7ft to 1ft SSE swell with offshore wind, but it’s really small—barely worth the wetsuit. The next proper note is Wednesday September 23, with a 3ft to 3ft S swell, long 12 to 13-second period, and clean offshore winds in the afternoon. Combined energy around 248 to 255, moderate power, and the S direction is exactly what Montoya wants. It’s promising but it’s a long way out, so keep an eye on it.
Overall, Wednesday the 16th is the one to circle. The rest is either flat or just ordinary, but that morning glass-off will be remembered.
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.
