Alright, Rusty here again, let's break down what's coming for La Isla.

The first several days are going to be a bit of a grind. Nothing terrible, but nothing that'll make you skip work. The real juice shows up in the second week, kicking off around the 14th of July.

Starting off Monday, July 6th, at La Isla (reef and point) , we've got clear skies and a long-period SSW groundswell running 6ft at 17 seconds. That's a ton of energy behind it, and that long period means it'll peel perfectly down the point. The water is running 70°, which is a very unusual 7° warmer than average for this time of year. The catch is a light cross-onshore breeze – only 5 km/h – putting a few ripples on it and keeping the conditions marginal. It's surfable, but not the prime window.

Tuesday and Wednesday, the 7th and 8th, see the swell drop a bit to around 5ft and then 4ft, but the period stays solid at around 15 to 16 seconds. Winds stay light and mostly cross-shore. The energy is moderate, between 1748 and 657. You'll get some waves, but the quality reports are still marginal. This tune carries on through the whole first week and into the start of the second. It's clean, but just... average.

Now here's where it gets good. Tuesday morning, July 14th, is a real standout. We get a cross-offshore wind from the South at 10 km/h. The swell is a clean 4ft from the SSW with a 13-second period. The energy is moderate at 581, but that cross-off breeze will have it glassy and well-shaped. This is a very good session on offer.

The absolute big ticket is Saturday, July 18th. The afternoon is going to be insane. Swell jumps to 10ft from the SSW with a massive 17-second period. The energy is huge at 4615. The wind shifts to a cross-offshore from the South at 15 km/h. This is big, powerful, and clean. At over 8ft, this is expert territory only. The morning of the 18th will also see 10ft sets (5536 energy) but with a light cross-shore wind.

Sunday the 19th holds at a solid 7ft from the SSW. The morning is a bit choppy with a cross-on wind, but the afternoon cleans right up with that cross-off breeze again. Another great option for the experienced crew.

After that, the swell eases into the 20th and 21st of July, dropping to around 6ft and then 4ft, with the wind staying mostly favourable for clean conditions. The 17th of July also shows a wild card: a tiny 3ft swell, but with a ridiculous 23-second period. That's a very long-period groundswell, and on this point, it could deliver some incredibly long, lined-up walls, even at that smaller size.

So, don't bother with the first week. Mark your calendar for the morning of the 14th and the afternoons of the 18th and 19th. The 18th is the big one for experts.

Rusty.

Information about the La Isla Surf forecast

The above surf forecast table for La Isla provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Isla can be found by selecting the local surf guide option on the grey menu. Our La Isla 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 (La Isla) 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 La Isla 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.
