The Lowdown
Alright, let’s talk about Montoya. The forecast starts Saturday the 29th of August, and for the first few days, there’s nothing worth paddling out for. We’ve got a long stretch of flat and choppy water through the weekend into the start of the week, with swell barely a whisper.
From Saturday the 29th through Monday the 31st of August, we’re seeing tiny east swell, only about 1ft to 2ft, and the wind is a mess – mostly cross-on or onshore. The water temp is about average for this time of year, nothing special.
Tuesday the 1st of September is more of the same – a bit more energy on that east swell around 2ft, but still cross-on wind ruining any chance of a clean wave. The combined energy is weak (73).
Then, Wednesday the 2nd of September morning offers a glimmer of hope. The wind goes glassy – dead calm – and the swell is around 2ft from the east at 9 seconds. The energy is still modest (80), but it’s surfable – just very ordinary. It’s the best of a bad lot so far.
Thursday the 3rd of September afternoon is another glassy moment with a 2ft east swell, 10-second period, and that glassy wind. Combined energy is low (67). It’s clean but tiny.
Friday the 4th of September and Saturday the 5th are a letdown again with cross-on wind and weak, confused swell.
Now, hold onto your board. Sunday the 6th of September sees a big spike – 8ft from the SSW in the morning, with combined energy of 826 (moderate to strong). But the wind is a dirty cross-on at 15-22 mph. It’s powerful but blown out. This is expert-only territory due to size, and the conditions are poor.
The standout of the whole forecast is Monday the 7th of September. We’ve got a 7ft south swell rolling in with a 12-second period, and the wind is only a light cross-shore at 6 mph. The combined energy hits 1040 (strong wave energy). The morning is the pick – that long-period groundswell will wrap around the point and reef setup, giving well-shaped, powerful waves. It’s intermediate to expert level, but the clean conditions make it the best on offer. Just watch out – crowds are possible here.
Monday afternoon holds 6ft but the wind swings to moderate cross-shore at 12 mph with a cross-chop, so the morning is your window.
After that, it drops off again. Tuesday the 8th of September is fresh and lumpy. Wednesday the 9th of September morning sees a 5ft SE swell at 12 seconds with light cross-on wind – marginal, with some ripples.
From Thursday the 10th onward, the swell fades and the wind stays messy. The last decent mention is that Monday the 7th.
So if you only surf one day, make it the morning of Monday the 7th of September at Montoya. That south groundswell and light wind will give you the cleanest, most powerful waves of the whole 16-day window. Everything else is a fight against the wind or flat.

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.
