The Lowdown
Alright folks, Rusty here. Let's be straight up: the next week and a half is a total bust around Montoya. From Friday, July 31st, all the way through to Wednesday, August 12th, we're looking at tiny, gutless waves in the 1ft to 3ft range, and the wind is coming from every wrong direction, chopping everything up. There’s a brief flash on Wednesday morning, August 5th, with a 2ft SSE swell and a light offshore that'll clean it up, but the energy is weak (73), and you'll be waiting a long time between sets. Those first 13 days are a dead zone for any proper surfing.
But hold onto your board, because Thursday, August 13th, flips the script. A big pulse of SSW swell rolls in overnight, and Thursday morning we're looking at a solid 8ft of it. The wave energy is a powerful 681, and the wind is a light offshore from the NNE. It's gonna be clean and heavy at Montoya. The direction is a bit off the best (SSW vs optimum S), but at that size with offshore wind, it's going to be the pick. The period is short (8 seconds), so it'll be a punchy, dumpy wave – experts only at that size. The spot can get crowded "sometimes," but on a day like this, I'd expect it to be packed.
And then there's Friday, August 14th. This is the real beast. The swell cranks up to a massive 12ft from the S with a very long period of 13 seconds. This is a true groundswell with incredible energy (4458). The morning wind is a light cross-shore from the NE, not perfect glass, but it'll hold the shape. This is strictly for the pros. With that long period hitting a beach-and-point setup, expect some close-outs on the beach, but if you find a good line on the point, you'll be on some freight trains. Saturday, August 15th, still has 10ft of swell from the SSE with a similar period (14 seconds), but the wind is a stronger 15 mph cross-shore from the NE, making it choppy and lumpy. The standout windows are Thursday morning for clean conditions and Friday morning for the sheer size and power. The long-range stuff is less certain, but right now it looks promising.
So, to sum it up: we've got a long flat spell, but next week is going to explode. Mark your calendars for the 13th and 14th.

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.
