The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the Montoya area.
To be honest, the next week and a half looks pretty grim. We’re staring down the barrel of a long stretch of poor conditions. From Sunday the 19th right through until the morning of Wednesday the 29th, there’s nothing worth getting excited about. The wind is all wrong – mostly onshore or cross-onshore, keeping things choppy and messy. Swell heights are tiny or unfocused, with weak energy levels (often under 200). It’s a real flat spell.
The first bit of hope shows up on Wednesday the 29th. The morning brings a clean 6ft south swell (period of 6 seconds) with a light cross-offshore breeze from the WSW. The wind state is clean, and the energy is moderate at 276. The afternoon picks up a touch more size, hitting 6ft from the SSW, still clean with that WSW breeze. The energy bumps up to 357. This is the best we’ll see in the whole 16-day window. For a beach and point setup like Montoya, that clean, cross-off wind is a big deal. Get on it Wednesday if you can.
Looking further out, there’s a big pulse of energy arriving on Friday the 31st and into August. We’re talking a very long-period south swell (14-15 seconds) with heights around 5ft to 6ft, and the combined energy is massive – over 1000, hitting 1395 on the morning of August 1st. That’s a lot of water moving. However, the wind is a problem. It’s blowing cross-onshore from the east, so the surface will be choppy and bumpy. The swell direction is also a bit east of south, which isn’t ideal for Montoya’s optimum. It’s a powerful, long-period groundswell that would be better at a point or reef, but with the wind on it, it’s a frustrating prospect. The morning of August 2nd sees a 8ft swell from the ESE with a light cross breeze, but that’s big for a beach break and the wind is still not off.
So, the standout is Wednesday the 29th. That’s your window for clean, fun waves. The rest of the time, it’s either flat or blown out. The water temperature is about average for this time of year, so nothing unusual there.
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.
