The Lowdown
G'day, I'm Rusty. Let's have a look at the surf outlook for Montoya. It's a beach and point break, and it's fairly consistent, but mate, it's a grim run for the next couple of weeks.
The water temperature is about average for the time of year, nothing wild going on there, but I wouldn't be worrying about that with the mess we've got coming.
Right off the bat, from Wednesday the 12th of August through to Tuesday the 26th of August, it's a poor stretch. There's surf on the cards, but the conditions are just wrecked. The wind is constantly cross-on or onshore, making everything choppy, lumpy, or messy. The wave comment for every single session in that first week is "poor surf conditions." The swell energy sits between moderate and strong, ranging from 185 to 858 in the combined energy reading, but it doesn't matter when the wind's blowing the guts out of it.
We do get a little glimpse of something better on Sunday morning, the 16th of August. The wind swings north-northeast at a light 3 mph, going cross-offshore, giving us clean conditions. The wave height is a small 4 ft from the east, with an 8-second period. The combined swell energy is only 185 (weak), and the wave comment says "surfable waves but very ordinary conditions." It's the best of a bad lot, but honestly, it's nothing to get excited about. It's that short period, so the waves will be a bit crumbly and hard to line up.
Then we hit a tough patch. From the 19th of August, the swell builds. The morning of the 19th sees 8 ft from the southeast, but the wind is howling onshore at 22 mph, making it lumpy. By the afternoon, it's 8 ft from the southeast with 28 mph cross-on winds, creating messy, strong conditions. This is only for experts, and even then, it's a battle.
Thursday morning, the 20th of August, finally delivers some clean conditions. The wind goes offshore from the west-northwest at 28 mph (strong breeze). The wave height is a solid 7 ft from the south-southeast, with a 10-second period. The combined swell energy is 858 (moderate). The wave comment says "marginal." Here's the problem: that offshore wind is so strong, it will be incredibly hard to paddle into the waves, and it's a beach and point setup, so the conditions will be howling and tough. It's too big and too windy for a fun, relaxing surf.
Forget kite surfing here, the wind is mostly cross or onshore, not consistent for that either.
By the 22nd of August, the swell drops right off, with energy reading as low as 18 and 42. The rest of the month is a write-off, with poor conditions right through to the 27th.
That Sunday morning the 16th of August is the standout, but it's a tiny window of clean, small conditions. Thursday morning the 20th of August is the biggest, cleanest looking swell, but that wind is a beast. Promising, but less certain for a good wave.
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.
