The Lowdown
Alright, let me tell you how it's looking at Montoya for the next couple of weeks. Honestly, I gotta be straight with you – it's a tough run ahead. The setup is a beach and point break, and it's fairly consistent, but the wind and swell just aren't playing nice for most of the period.
Right now, and for the next several days, the conditions are pretty poor. We've got a mix of onshore and cross-shore winds, and the swell is a mess. The water temp is about average for this time of year, nothing wild there.
The first real glimmer of hope doesn't show up until Friday, July 24th. The afternoon session looks okay. The swell is a small 3 ft coming from the ESE with a period of 8 seconds, and the wind will be a cross-offshore breeze from the WSW, keeping things clean. The combined energy is moderate at 214, so it's not a flat day, but it's definitely ordinary. It's a light session, nothing to get too excited about.
Then, we’ve got a bit of a gap. The next real standout arrives on Saturday, August 1st. This is the best of the whole run. The morning is looking tidy. We've got a 5 ft swell from the ESE, but here's the catch – the period is 13 seconds, so that's a proper groundswell. This kind of long-period swell can be a little tricky on a beach break, but at a point and reef setup, it should wrap in nicely. The wind is a light cross-off from the WNW at 9 mph, keeping things clean. The combined energy is strong at 843, so there's plenty of power. This is your window. It's a bit over a week away, so keep an eye on it, but it's the one to aim for.
Outside of those two windows, the forecast is grim. There's a lot of strong wind, big lumpy swell, and a lot of onshore slop. There's a big pulse of energy around the 29th to the 31st, with swell heights over 8 ft and combined energy in the thousands, but the wind is screaming onshore, making it an absolute mess. That's expert-level power and size, but with those winds, it's more of a survival mission than a surf session. Honestly, for a few days there, it might be more interesting for the kite surfers than us paddle guys.
So, keep your powder dry. The best bet is that Saturday morning, August 1st. The rest of the time, it's a waiting game.

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.
