The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the line for us.
Right now, things are flat as a tack. For the next few days, we are looking at a real dry spell. Sunday the 30th of August kicks off with barely a ripple, and that runs right through until Wednesday. It’s going to be a proper wait for anything worth paddling out for.
We start to see a little bump around Wednesday the 2nd of September, with a small 2ft easterly swell showing up. The wind is looking alright, light and offshore, but the wave energy is weak (75). It’s surfable, sure, but nothing to write home about – a real knee-slapper for the patient ones.
Thursday the 3rd is much the same, with a similar size and direction but a bit more energy (101) in the afternoon. Still, it's a mediocre offering.
Now, hold onto your board, because things get interesting at the start of the second week. By Monday the 7th of September, we’ve got a proper pulse of swell arriving. Montoya (beach and point) is the only game in town, so that’s where we’re looking. The swell jumps up to a solid 10ft from the SSE, with a very long period of 16 seconds. The combined energy is a massive 3887 – you’ll feel that one in your chest. And get this: the wind is glassy. Zero. Nada. That means perfect, clean conditions.
This is for experienced surfers only. That 10ft, long-period groundswell is going to unload, and at a beach and point break, the long period can make the waves wall up, especially on the beach sections. It might be better to hunt for the point at Montoya to get a more open face. This is the standout of the whole outlook; the swell size, the period, and the glassy wind all come together. Be aware though, it can get crowded there sometimes. Monday morning is your window.
The afternoon takes a bit of a hit with a cross-onshore breeze coming in, chopping up that beautiful morning glass. Tuesday the 8th sees the swell drop and the winds turn less favourable, and after that, it’s back into the doldrums for the rest of the period.
So, the bottom line: a long, flat start followed by one killer morning for the big-wave crew. Get ready for the 7th.
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.
