The Lowdown
Hey folks, Rusty here. Let's have a look at what's cookin' for Montoya over the next couple of weeks. Honestly, it's a pretty bleak stretch for paddle surfing, so don't get your hopes up.
Right off the bat, we’ve got a bit of swell on Thursday afternoon with a 3 ft SE swell, period of 12 seconds, but the wind is a light cross-shore and the overall energy is weak (296). The water temp is sitting at 52°, which is about average for this time of year. But the call on the day is "marginal", so it's not really worth getting excited about. That's basically the only wave on offer for over a week.
After that, it’s a dead zone. From Friday the 28th of August right through to Thursday the 3rd of September, every session is rated as poor surf conditions. The swell is tiny, often under 3 ft, and the wind is mostly onshore or cross-onshore, messing up what little is there. It’s just not happening.
We start to see a bit of change on Friday the 4th of September. There’s a tiny 1 ft SSE groundswell with a very long period of 16 seconds. It’s "surfable but very ordinary", and the wind is a clean offshore from the north. The combined energy is still only moderate (109). That's a crumb of hope, but the size is so small it's barely a wave.
Things get a bit more interesting heading into the second week. A solid pulse of SSE swell is due around Tuesday the 8th of September, with waves hitting 6 ft to 6 ft and strong energy levels (463 and 492). The period is short, though, around 7-8 seconds. The wind will be a moderate cross-shore from the southwest. This is powerful but messy—definitely not for beginners. It's more of a kite-surfing setup than a clean paddle session, to be honest. That energy tapers off through the 9th but stays in the moderate to strong range (328-362).
The very end of the outlook, on Friday the 11th of September, shows a 5 ft E swell with a short period (6 seconds) but with clean, offshore cross-off winds from the west. That’s the best looking window for a proper surf, but remember, it's way out there and could change.
So, what's the standout? If you had to pick one, the morning of Friday the 11th of September with the offshore wind is the most promising for clean conditions, even if the swell is a little short-period. Keep an eye on that.
Signing off,
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.
