The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Montoya over the next couple of weeks.

Right off the bat, I gotta be straight with you: the first few days are a bit of a struggle. We’ve got a tiny 1ft SSE swell arriving on Friday the 31st of July, but with a 15 mph cross-offshore breeze, it’s just not gonna be worth paddling out for. The water’s sitting at 54°, which is a touch warmer than normal for this time of year, but that’s about the only upside.

We do get a glimmer of hope on the morning of Saturday the 1st of August. The wind switches to a light offshore from the NW at 6 mph, and we see a clean 4ft east swell with a 10-second period. The combined swell energy is moderate at 229, and the conditions are clean. It’s not a world-beater, but for a little Saturday morning session, you could do a lot worse. Mind you, the crowds are *sometimes* an issue, so you might have to share the peak.

The real standout, and the one I’d circle on the calendar, is the morning of Thursday the 13th of August. We’ve got a solid 8ft swell rolling in from the SE with a 10-second period, and the wind is a clean cross-offshore from the NNE at 12 mph. The combined swell energy is strong at 1060, and the conditions are clean. This is a powerful, punchy wave. At 8ft, it’s getting into the territory where it’s more for the experienced crew – beginners might find it a bit much. The 10-second period means it’ll have some decent shape but won’t be too tricky to handle. This is your best bet for the whole forecast window.

The week after that looks to drop off again, with smaller swells and more cross-shore winds dominating. The morning of Friday the 14th of August offers a 5ft ESE swell with a clean cross-offshore breeze, but the energy is a bit lower and it’s not quite the same calibre as the 13th.

So, in short: the start is a write-off, the first Saturday morning is a light option, but the real charge is on Thursday the 13th of August. Set your alarm for that one.

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.
