Alright, Rusty here. Let’s break down what K-38’s got for us over the next couple weeks.
Right off the bat, it’s a tough start. We’re looking at a long stretch of poor conditions through the first week of July. That WNW wind is just hammering us – cross-onshore or straight on, and it’s choppin’ up everything. There’s some energy in the water (moderate energy in the 400–500 range), but with that wind, it’s not worth paddling out. You might as well save the gas and wait.
The first real chance shows up on the morning of Wednesday, July 8th. The wind backs off a little to a gentle breeze, still cross-onshore, but the surf report goes from “poor” to “marginal.” We’ve got a 4ft SSW swell with a long 16-second period – proper groundswell, good for shape, but could be a bit straight on the reef.
Thursday, July 9th is the first standout. That morning, the wind swings light SW, only 6 mph. Still cross-onshore, but light enough that the surface cleans up with just small ripples. The swell holds at 3ft from the SSW, with that nice 16-second period. The combined energy is a solid 603 – moderate but punchy. This is the best we’ve got early on. Get out there early, it’s your best bet.
After that, it drifts back into marginal or poor through the second week. Swell drops, period drops. By Monday, July 13th, we’re down to 3–3ft. Not much to get fired up about till Friday, July 17th. The morning shows a 2ft swell from the W with a 17-second period, energy jumping to 511. The wind is onshore, though, so it’s a long-range guess – could be some longer-period lines if the wind plays nice, but don’t bank on it.
Overall, K-38 is a reef break that’s very consistent, but we’re in a rough patch. Thursday the 9th is your best call – clean-ish, long-period groundswell from the SSW, and crowds are only “sometimes” busy, so you might get a few waves to yourself. Not magic, but it’s surfable.
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.
