Table - best surf conditions forecast for La Isla over the next 16 days.
Alright, let’s break it down. The surf shows up Sunday afternoon, July 12th, but it’s pretty weak. The real deal hits Monday morning.
Monday the 13th is the one to circle. La Isla (reef and point) gets a solid 5ft SSW groundswell with a long 15-second period, and wave energy is pumping (1122). Wind is light and cross-offshore from the south – clean lines, proper for the experienced crew. That long-period swell is going to wrap nicely into the point. Water temp is 69°, which is much warmer than usual for this time of year.
Monday afternoon drops to 3ft but stays clean. Tuesday and Wednesday are smaller, 3ft to 5ft, with light cross-shore wind. Nothing bad, but not the peak.
Thursday the 16th afternoon brings back 5ft SSW swell, 13 seconds, with 9 mph southerly cross-offshore breeze – clean and strong (938 energy). Friday the 17th is clean again with 5ft. Saturday the 18th afternoon hits 6ft, 12 seconds, light cross-offshore wind. Good session.
Then we hit a flat spell from Sunday the 19th through Thursday the 24th – mostly 2ft to 4ft, with cross-shore or onshore wind. Not worth rushing out.
Friday the 24th afternoon spikes again: 6ft SSW swell, 14-second period, clean cross-offshore wind, and huge energy (1085). That’s a promising long-range call for experienced surfers. Saturday the 25th morning sees 7ft SSW swell, 14 seconds, but with a light cross-onshore breeze – big and blown, better for experts only. After that, it fades into the 27th with more onshore wind.
Best bet: Monday the 13th morning. Clean, strong, long-period groundswell at La Isla. Friday the 24th afternoon is worth watching. Everything else is small to moderate, with a few clean windows.

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.
