The Lowdown
Alright, this is Rusty, and I’m breaking down the next 16 days for Montoya.
To be honest, it’s a tough outlook. Surf is on the small side and mostly messy for a long stretch. The first time you could even consider paddling out is Monday the 14th, but it’s not much. Forget the weekend of the 12th and 13th – strong cross-onshore winds (18 to 22 mph) and rising, lumpy swell up to 7 ft make it a complete washout. The water temp is about normal for the season.
Monday morning the 14th gives a tiny 2 ft of S swell with a 10-second period and a light offshore breeze from the NE. It’s clean, but the energy is weak (171), so you’re looking at small, indifferent waves. The rest of that week is tiny and ordinary, with a lot of cross-onshore chop and sizes dropping to 2 ft by Tuesday.
The one day that stands out, and you really have to wait for it, is Thursday, September 24th. That’s the pay-off. We get a clean 5 ft SSE groundswell with a long 12-second period and fresh offshore winds from the NW. The energy is strong (612), so there’s real power in the water. That kind of groundswell will set up nicely at the point, offering some proper, clean-faced waves. It’s solid enough to be for competent surfers only. Expect crowds to be likely at this spot when it’s like this. The morning of the 26th also has a clean little 2 ft groundswell with glassy offshore wind, but it’s soft (121 energy).
So, the bottom line: for Montoya, it’s mostly a waiting game. The only real standout is the 24th of September. That’s your day. Don’t get your hopes up for the rest.

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.
