The Lowdown
Alright, folks, Rusty here. Let's have a look at what we've got for Montoya over the next couple of weeks. I won't sugarcoat it – this is a long, painful stretch of waiting for the ocean to turn on. The first decent wave we see is over a week away, so strap in.
We are looking at Montoya, a beach and point break. The water temp is sitting at 56°, which is a touch warmer than normal for this time of year. Feels a bit weird, but I'll take any extra warmth I can get.
The outlook starts with a flat and ugly spell. Saturday the 12th through most of the second week is a write-off. We've got a weak S swell on Monday morning the 14th with a tiny 2ft wave and very ordinary conditions. The energy is weak, measuring just 177. A slight north wind offers a clean face, but there's hardly any push. It's the best of a bad bunch for now, but that's not saying much.
The real story, the only time you should even think about paddling out, is Thursday the 24th and Friday the 25th. We finally get a proper groundswell from the south, with a solid 12-second period (a long period groundswell) which means proper energy and shape. That combined swell energy jumps right up, hitting between 690 and 700 over those days – finally some grunt! The wave heights are in that 4ft to 5ft range, clean and well-defined.
Now, on Thursday morning the 24th, we have a light offshore wind from the NW and clean conditions. It's going to be glassy, with those long lines from the S. Thursday afternoon is even better – a light breeze and very good surf conditions. This is the standout of the whole outlook. Friday the 25th is good too, with clean 5ft waves, but it's a touch more marginal due to tides. Grab the 24th if you can. The wave direction is from the south, and that is exactly what this spot wants to see. Expect some crowds though, as this is a spot that can get busy when it's on.
After that, it fades out again quickly over the 26th and 27th with dropping swell and onshore winds.
So, here's the truth: Most of this 16-day window is dry sand and sadness. But that Thursday the 24th and Friday the 25th is your window. Mark it on the calendar and be ready for a session that will make the wait worthwhile.
Rusty, signing off.

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.
