The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer over the next couple of weeks.
Right off the bat, I gotta be straight with you—it's a pretty grim start. We're looking at more than a week of nothing special. The first real chance to get wet is Wednesday afternoon the 15th, but honestly, it's just small. Montoya is showing 3 ft of east swell, period is a short 8 seconds, and the energy is weak at 92. The wind is cross-off, so it’ll be clean, but the conditions are very ordinary. You might get a few grovelly ones, but there's no real juice.
Thursday and Friday the 16th and 17th are a write-off with poor surf and building winds. Saturday morning the 18th is a tease—glassed off with 3 ft of east swell, energy 136, making for a clean little surf. But it’s still just surfable, not exciting. From there, it’s a long, ugly stretch of onshore wind and poor conditions that lasts all the way through to the 25th.
Now, hang in there, because things get interesting. The real standout is Monday the 27th of July. That morning, Montoya is looking absolutely firing. We’re talking a solid 7 ft swell from the SSE, with a super long 14-second period pushing a massive 1706 combined energy. The wind is a clean cross-off breeze at 10 km/h. That's a proper groundswell and it's going to be good. The water temp is about 51°, which is average for the time of year. This is big, powerful surf, and at over 5 ft, it's not for beginners. Over 8 ft would be expert-only, but this is right in the sweet spot for any experienced surfer looking for a serious session. The afternoon of the 27th is still excellent, 6 ft and 14-second period with 1154 energy and clean cross-off wind. Mark that Monday in your calendar.
The 26th of July afternoon is a decent warm-up, 4 ft from the SSE with a 10-second period, 430 energy, and clean cross-off wind. It's the calm before the storm.
After that peak, the 28th rolls around and it’s back to onshore junk, so don't get greedy. The 30th has a bit of size but the wind is messy.
So, to sum it up: the first week is a total bust. The best window is the afternoon of the 26th, and the absolute standout is Monday the 27th. Get your board ready for that one. It’s a long-range call, but it looks promising.
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.
