Alright folks, Rusty here. Gotta be straight with ya – the next couple of weeks at K-38 are looking like a bit of a struggle. The reef is exposed to the swell, but the wind is just not playing ball for most of this run.
We kick off on Friday, July 3rd. There’s some waist high 3 ft SSW swell rolling in with a nice long 16-second period, which usually means proper groundswell. The water temp is sitting at 67°, which is pretty much where it should be for this time of year. But the problem is that persistent WNW breeze blowing 12 mph, putting a cross-on chop on the face. It’s messy, and the wave comment is calling it poor. That’s the story for the first week, honestly. Saturday, Sunday, Monday... the pattern holds. The swell energy jumps up over a few days, hitting a combined energy of 1049 on Wednesday the 8th, which is solid, but the wind is just never clean. Even though the waves are getting into the waist to chest high range (4 ft) on Tuesday and Wednesday, that wind keeps it ugly.
We finally see a glimmer of hope around Thursday the 9th and Friday the 10th. The swell drops back to around 3 ft, but the wind swings around to the south and southwest, going cross or even offshore for a bit. The period is still a solid 15-16 seconds. For a reef like K-38, that’s the kind of window you want. It’s not a stand-out by any means, and the score is only marginal, but if you’re desperate, Thursday afternoon and Friday morning with that clean cross-shore breeze will be the cleanest waves we see. After that, it’s back to onshore junk and smaller surf through the second week. The swell energy dips back down to the 200-400 range and the waves shrink to knee to waist high.
Looking into the second week, there is a little bump on Saturday the 18th with a combined energy of 613 and 3 ft of SW swell on a 18-second period, but again, the wind is on it. It’s a long way out and the pattern is stubborn.
In short, there are no true standouts in this forecast. It’s a week and a half of choppy, wind-affected surf. If the wind predictions shift, this place could fire, but right now, you’re better off waiting for a better forecast.
Rusty.

Information about the K-38 Surf forecast
The above surf forecast table for K-38 provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at K-38 can be found by selecting the local surf guide option on the grey menu. Our K-38 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 (K-38) 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 K-38 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.
K-38 is 11 km (7 miles) from the very large city of Rosarito. If you plan a holiday in Baja Norte, look for hotels and other accommodation in Rosarito. Rosarito has rooms for a wide range of budgets as well as cheap car hire and transport links.
