The Lowdown
Alright, let’s talk about Montoya over the next couple of weeks. I’ll be honest, it’s a rough stretch for the most part. The water is 55°F, which is a touch warmer than usual, but that’s about the only thing going for us. The first few days are tiny, with swell heights around 1.0 ft to 1 ft, from the SSE, with short periods. The wind is onshore or cross, so it’s all choppy and poor.
There’s a big pulse of energy on Saturday, September 12th – the combined energy hits 2124, with a 10 ft south swell at 10 seconds. That’s a lot of water, but the wind is a strong cross-onshore at 25 mph, making it a total blustery mess. For a beach and point break, that’s more of a kite session than a surf session. The energy stays up into Sunday the 13th with a 7 ft to 6 ft south swell, but the wind is still onshore, so it’s blown out.
The one bright spot, and I mean the only one, is the morning of Monday, September 21st. We’ve got a 4 ft south swell with a short 6-second period, but the wind is offshore from the NW at 6 mph, and it’s clean. The combined energy is moderate at 213, and the conditions are expected to be good. That’s your window. It’s not a big swell, but with clean, offshore winds, it’ll be the best you’ll get. The short period means the waves will be a bit weaker and more crumbly, but for a clean session, it’s worth it.
After that, it’s back to small, weak swell and cross-off winds, so nothing else is worth getting excited about. It’s a lean run, but that Monday morning might just give you a couple of fun ones.

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.
