The Lowdown
Alright, let’s break it down. For Montoya, the next two weeks are pretty grim overall. We’re looking at a long stretch of small, weak, and messy surf.
The first real chance of a wave won’t be until Wednesday, September 2nd. It’s a tiny 2ft easterly swell with a weak 9-second period. The energy is low, at 57, but the wind is light and offshore, so it’ll be clean. It’s a longboard or micro-swell only. The 6th of September sees a pulse of size, with a 7ft southerly swell on Sunday morning and an 8ft southerly swell on Sunday afternoon – that’s a lot of water, but the period is short and the wind is a nasty cross-onshore, making it choppy and ugly. The combined energy hits 1434, which is strong, but the quality is poor. For a beach and point set-up, that’s more of a kiteboarding day.
The one session that stands out is Tuesday, September 8th. We’ve got a clean 4ft SSE swell, with a 10-second period, giving moderate energy at 344. The wind is glassy in the morning, and the water is a touch warmer than normal at 54°. That’s your window. The waves should be clean and have some shape, and it’s the only time the conditions really come together. The swell direction from the SSE is a good match for the spot. Crowds are possible, so be there early.
The morning of the 9th of September also looks clean with a glassy 4ft SSE swell, but the energy drops off. The rest of the second week is a washout: small, onshore, and choppy. It’s a long wait for one decent morning, but that Tuesday morning is the one to chase.

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.
