The Lowdown
Alright, folks, Rusty here. Let’s size up what’s coming for La Isla over this stretch.
We’re looking at a solid run of groundswell, with periods often reaching into the 14-15 second range, meaning proper, lined-up waves. Early in the week it’s a bit mixed, but the session to really circle comes up on Wednesday the 12th and into Thursday the 13th. Those mornings see clean, offshore breezes and waist-to-chest high sets, with the swell clocking around from the SSW and holding that long period. The energy’s moderate, around 800-1000 in the water, so there’s push without it being a washing machine. It’s a reef and point break, so that long-period swell will wrap in nicely. Not a spot for beginners when it’s above 5ft, and on Thursday morning we nudge up toward that mark, so give it the respect it deserves.
By Sunday the 16th, things change up. We’ve got a shorter period S swell, down around 8 seconds, with wind picking to a moderate breeze. The wave height hits 7.5ft – that’s expert territory only. The shorter period keeps it from being too unruly, but the power’s there (energy over 1300), and cleanup sets will be raw. Monday the 17th stays similar, with 6-7ft waves out of the south and that same short-period punch. This is not a learner’s window.
Later in the outlook, around Friday the 21st, we see a drop in size and a shift back to long-period SW swell, but the wind turns cross-onshore, so it gets a bit soft and crumbly. If you’re picky, hold out for Sunday the 23rd afternoon when the breeze cleans up again and those waist-high runners return. Crowds are "often" out at La Isla, so expect company on the better days, especially when it cleans up mid-week.
There’s a gap on the 20th where conditions just aren’t worth the paddle, but overall, there’s plenty of good water to chase if you pick your moments.

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.
