Table - best surf conditions forecast for Montoya over the next 16 days.
The Lowdown
Alright, let’s talk Montoya in feet and miles. It’s a beach and point break, fairly consistent, exposed to the south. Water temp is about 54°F, a touch warmer than normal for this time of year.
The start is quiet. Monday afternoon has a tiny east-northeast wind swell at 3 feet, cross-on wind, energy is weak. Not worth it.
Tuesday the 1st stays small, east swell under 3 feet, wind onshore in the morning, cross-on in the afternoon. Still nothing.
Wednesday the 2nd is a clean but tiny session. Swell at 2 feet from the east, cross-off wind in the morning, offshore in the afternoon. You’ll be on glassy little waves.
Thursday the 3rd gets a little bump. Swell 3 feet from the east, 10-second period, energy moderate. Cross-off wind, clean. Surfable but ordinary.
Friday the 4th drops back. Tiny east-southeast swell, light winds but not favorable.
Saturday the 5th is messy. Morning clean but 2 feet from the south, afternoon jumps to 5 feet from the south-southwest, but the period is a lousy 6 seconds, wind cross. Lumpy and short-period. Might be better for kite surfing.
Sunday the 6th brings size. Morning 7 feet from the south, 10-second period, energy strong. But cross wind, choppy. Afternoon 6 feet with a fresh 22 mph cross-on wind. Ugly.
Monday the 7th stays big, 6-6 feet from the south-southeast, 8-second period, onshore or cross-on wind. Energy strong but conditions poor.
Tuesday the 8th drops to 3 feet from the south-southeast, cross wind, moderate energy. Still not clean.
Wednesday the 9th is a tiny clean morning, 2 feet from the south-southeast, cross-off wind. Barely a ripple.
Thursday the 10th sees 3-4 feet from the east, onshore wind, moderate energy. Marginal.
Friday the 11th is small, 3-3 feet from the east, mostly clean but with a fresh breeze. Nothing special.
Saturday the 12th is clean and steady. 4-5 feet from the east-southeast, 5-6-second period, energy moderate. Surfable but short-period.
Now the standout. Sunday the 13th. Morning gives 4 feet from the east, 9-second period, energy moderate, and offshore wind from the northwest. Clean. The wave comment says “expect good surf conditions.” That’s the best of the run.
Monday the 14th gets bigger, 5-5 feet from the east, 11-second period, but cross-on wind, energy strong. Choppy.
Tuesday the 15th closes out. 5-5 feet from the east-southeast, 12-second period, energy strong, cross-off wind clean but marginal scores.
Bottom line: morning of Sunday the 13th is your best bet. The rest is small, messy, or ordinary. Second week shows size but wind is a gamble. Crowds are possible at Montoya, but with the quality, it might not be packed.

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.
