Alright, this is Rusty. Let me break it down for you in feet and miles per hour.
First up, the surf at Montoya (Costa Careyes). We’re looking at a slow start. Water temp’s 51°F, about average for the time of year. The first few days? Pretty grim. Swell stays tiny, under 3 feet, coming out of the ESE with cross-off winds Wednesday morning. Energy is weak (61). It’s a float-around day, not a surfing day.
Thursday morning shows a little life: 2ft from the east, 10-second period, and an offshore breeze from the NNW at 6 mph. The offshore wind makes it glassy, but the waves are just too small. Energy reads 80. Surfable but nothing to write home about.
Friday and Saturday the swell creeps up to 2-3ft, but the wind turns onshore or cross-onshore, making it choppy. Energy climbs into moderate range (169 to 409), but the quality sinks. Saturday morning brings a long 14-second groundswell from the ESE, but with cross-shore winds and small waves, the long period might make it break too straight for the beach—better luck on the point.
Sunday the 12th is your first real chance. Morning: 3ft from the ESE, 13 seconds, and a cross-off wind from the WSW at 9 mph. Clean faces, light breeze (263 energy). It’s marginal, but it’s a window. Monday the 13th jumps to 5ft from the SW, but the period tanks to 6 seconds—short, bumpy, weak. Energy at 272, but shape is poor. By afternoon it’s 5ft with strong cross-off wind, still short period.
One small moment: Tuesday the 14th, early. Dead calm—zero wind—and 3ft from the south with a short 6-second period. Those glassy conditions are golden for clean rides, but the waves are small and weak. If you want a glassy knee-high wave, that’s your shot.
The real standout? That’s Tuesday the 21st of July, about a week and a half out, so keep an eye on it. Morning: 10ft from the south, 8-second period, and a cross-off wind from the WNW at 16 mph. The combined energy is a strong 1353—powerful swell. Afternoon drops to 8ft but still carries 1139 energy. That size is expert-only. The break is a beach and point setup, so with cross-off wind, the point could handle it beautifully. Crowds are possible here, so plan ahead.
After the 21st, it fades fast back into small, onshore, choppy conditions through the 23rd. Not much to chase.
Bottom line: the first ten days are small and mostly ordinary, with one glassy morning on the 14th. The big one comes Tuesday the 21st of July—that’s the day to circle.
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.
