The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at Isla Vista.
Honestly, I’m gonna level with you. For this entire 16-day stretch, the surf just isn’t cooperating. We’re looking at a long, frustrating run of small, messy, wind-affected waves. The first real opportunity you might want to look at isn’t until Thursday the 27th of August, and even then, it’s only a marginal call. There's about a week of flat or poor conditions before we get to that.
The biggest issue is that nearly every day has a nasty cross-onshore breeze. Even when the odd long-period groundswell tries to push in, that wind just ruins the shape, especially for a beach and reef setup like Isla Vista. The water temp is running much warmer than normal for the time of year at 69°, which is a bit unusual but doesn’t help the wave quality.
Alright, so where’s the glimmer? The only time I’d even consider paddling out is on Thursday morning the 27th. We’ll see some waist-high swell, around 3 ft from the South, with a period of 12 seconds. That’s enough to wrap in a little, and the wind is forecast to be light offshore from the SW (6 mph). That early glass-off should give the south-facing parts of the beach a clean, lined-up look. The combined energy will be strong at (553), so there’s some punch there, but don’t expect perfection. It’s still a marginal tide-dependent scenario.
Beyond that, the forecast is a write-off. Even the bigger stuff on the 31st of August (roughly 5 ft to 6 ft from the WNW) is coming with a short, weak period and a nasty 16 mph cross-shore wind. That kind of setup is more for the kite crew than a surfer. The same story repeats through the first week of September, with small, weak swell and onshore winds. It’s a blank run, plain and simple.
In a spot like this, it doesn’t stay this bad forever, so keep an eye on the forecasts. For now, I’d save the wax for another week.
Rusty.

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