Alright, grab your board and listen up, it’s Rusty here.

Right now, things are looking pretty flat and quiet out at Montoya. We’ve got a bit of a lull to start, with no real surf to get excited about until the end of the first week. The water is sitting at 51°F, which is about normal for this time of year – nothing shocking there.

Tuesday morning kicks off with a weak 4ft SSW swell, but the wind is a cross-offshore breeze at 16 mph, so it’s clean but the energy is only reading 287 – just not enough push. That afternoon, the swell shifts to the south at 4ft with a period of 10 seconds and energy at 314, still not worth paddling out for. Wednesday and Thursday stay tiny – we’re talking 1ft to 2ft of swell, with energy numbers as low as 44 and 80. Thursday morning actually has a tiny bit of hope with a 2ft easterly swell, period of 10 seconds, and a light NNW breeze at 3 mph making it clean, but it’s just too small to get excited about.

Friday the 10th and Saturday the 11th see a small increase, but the wind turns onshore or cross-shore, messing up the surface. Saturday morning has a 2ft ESE groundswell with a long period of 14 seconds, and the energy jumps to 476 – that’s a lot of grunt for such a small height. The wind is cross-off at 16 mph so it’s clean, but the swell direction (ESE) isn’t the best match for the spot, so the waves will be a bit weak and straight. Saturday afternoon bumps to 3ft with energy at 559, but the wind goes cross-shore, creating a chop. Sunday through Tuesday of the second week stay small, mostly below 3ft, with poor conditions and no real standout.

Now, here’s where it gets interesting. The real highlight of the whole 16-day window is Sunday the 19th of July. That morning, we’ve got a solid 5ft ESE swell with an 8-second period, and for the first time, the wind goes clean offshore from the NNW at 12 mph. The combined energy is 297 – moderate – and the conditions are marked as good. This is a beach-and-point setup, so with that offshore wind, it should be clean and fun for intermediate surfers. Size is manageable, not too big for most, and the crowds are only *sometimes* a problem, so you might get some waves to yourself.

The next best chance is the following Tuesday the 21st of July in the afternoon. A small 3ft southerly swell with a 9-second period, and we get a light offshore breeze from the NNW at 9 mph. Energy is 149 – weak but clean. It’s a long way out, so keep an eye on it, but it’s a promising window for a quick session if the forecasts hold.

All in all, aside from that Sunday the 19th, there’s not a whole lot to get excited about. A lot of flat spells and onshore junk. But that one morning offshore window is worth marking on your calendar.

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.
