The Lowdown
Alright, let’s talk Montoya in feet and miles per hour. The first session that’s really worth suiting up for isn’t until Monday, August 24th. The weekend before that is just dead—nothing to get excited about.
Monday, August 24th, morning is where it’s at. We’ve got a 1.8m swell (call it 6 feet) coming out of the SSE with a 13-second period, and the wind is glassy—dead calm at 3 mph out of the SSE. Surfaces will be like a mirror. Combined swell energy is 977, which is moderate but solid enough. The water temp is about average for this time of year. It’s a beach and point break setup, and crowds show up sometimes, so you won’t be alone. This is perfect for intermediate surfers—not too big, and super clean.
The next few days have waves but the wind gets cross-shore and chops things up. By the 26th there’s some cleaner spells in the afternoon with a 1.3m (4 ft) SE swell, but nothing touches that Monday morning lap.
Then we hit a rough spot. From August 29th through the 31st the waves go tiny and weak, combined energy in the 30–70 range. About four days of barely a ripple.
On Tuesday, September 1st, the swell starts building again. Tuesday morning has a 1.9m (6 ft) E swell with 9-second period, cross-off wind, and clean conditions. But the real standout for the second week is Wednesday, September 2nd, morning. Pushing 2.2m (7 ft) SE swell with an 11-second period, cross-off wind, and combined energy of 2184—that’s strong wave energy. This is expert-only territory. The point break will help shape it up, but at that size, you need to know what you’re doing. Conditions will be clean but powerful.
After that, the swell fades out through the first week of September, with the last decent clean surf on Thursday the 3rd morning (2.1m / 7 ft SSE).
So the two highlights: Monday, August 24th for clean, user-friendly fun; and Wednesday, September 2nd for bigger, more challenging waves for the experts.

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.
