The Lowdown
Hey folks, Rusty here. Gotta be straight with you—looking at the 16-day window for K-38, it’s a pretty grim stretch. We’ve got a lot of days where the onshore flow or cross-onshore wind is just messing things up, and the wave heights are mostly in the ankle-to-knee-high range. It’s a tough run for paddle surfing.
The water temp is sitting at a pretty normal 68°F, no real anomaly to speak of, so you know it’s just our usual late August conditions.
The first real chance for anything decent doesn’t hit until Monday, August 24th, in the afternoon. That’s the one true standout in the whole period. The wind drops to dead calm, glassy conditions, and we’ve got a little 2ft SSW groundswell with a long 16-second period rolling in. The combined energy is moderate at 401. It’s not going to be big, but on that reef break with perfect glass, you’ll catch a few clean little runners. The optimum swell for K-38 is from the west, and this is coming from the SSW, so it’s a bit off-angle, but with no wind, it’s your best bet. This spot is very consistent, so there will be waves, even if small. Crowds are sometimes an issue here, so keep an eye out.
After that glassy window, from Tuesday, August 25th, right through to the end of the forecast on September 2nd, it’s back to poor surf. The wind swings onshore or cross-onshore again, mostly from the WNW or NW at 9 to 12 mph, just chopping everything up. There’s a small spike in swell on Saturday, August 29th, with 3ft to 4ft SW swell and combined energy climbing to 761, but the wind is a gentle cross-onshore, so the surface will be a mess. It might look more interesting for kite surfing than paddle surfing on those days.
Honestly, if you’re desperate, mark your calendar for that Monday afternoon glass-off. Otherwise, it’s a waiting game. Forecasts change, but right now, there’s not much to get excited about.
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.
