The Lowdown
Alright, this is Rusty comin' at ya with a look at what’s on the cards for Montoya over the next couple of weeks.
Look, I gotta be straight with you – the next week and a half is a proper struggle. We’re looking at a long, dry spell of poor conditions. From Sunday the 9th all the way through to the morning of Saturday the 16th, it's just one poor forecast after another. Strong, cross-onshore winds, short-period windswell, and choppy, messy surf. There's nothing to get excited about, and the combined wave energy goes as high as 792 but it’s all junk. The water temp is runnin’ a touch warmer than normal at 54°F, but that won't help the quality. Honestly, if you’re paddling out in that, you’re doing it for the love of it, not the waves.
Then, we get a little shift late on Saturday afternoon, the 16th. The wind swings to a light cross-offshore from the NNE and the sea state cleans up proper. It’s still small, with a 5ft east swell at 8 seconds, but combined energy is 271. It’s surfable, not a classic, but the first clean session we’ve seen.
Monday the 17th morning keeps that clean feel – a light WSW cross-offshore wind, 4ft east swell, period picking up to 10 seconds, combined energy 317. It’s rideable and tidy, but still on the small side for Montoya. Afternoon stays clean but drops off a bit.
The real standout, and I mean the *only* standout in this whole outlook, arrives on Monday the 24th of August. This is a proper pulse. Both morning and afternoon are looking excellent for experienced surfers. We’ve got a 7ft swell from the SSE with a very long period of 17 seconds in the morning, and 7ft at 15 seconds in the afternoon. The combined wave energy absolutely rips at 2500 and then 1846 – that’s serious power. And the wind? Near glassy, with a light offshore in the afternoon. This is a groundswell, long-period event, and it’ll be lining up best at the point. It’s a big one though – over 7ft – this is for the crew who know what they’re doing. Keep an eye on this date, it’s the clear winner on the board, but it’s a long way out so don’t pin all your hopes on it just yet.
Stay patient.

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.
