The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s headed our way for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a pretty bleak stretch. We’re looking at a solid run of weak, marginal surf that’s going to test your patience. The first real pulse of energy doesn’t show up until Friday the 31st of July, and even then, it’s not a total classic. The water is sitting at a balmy 75°, which is a whopping 8° warmer than normal for this time of year, so at least you won’t need a thick wetsuit.
The best bet, and the only real standout in this whole 16-day window, is going to be Oceanside Harbor (Oceanside-Harbor). This is a beach/jetty setup that’s very consistent. The pick of the week is the morning of Saturday, August 1st. We’ll have a clean 7ft swell rolling in from the S, with a period of 13 seconds. The wind will be light and onshore, so the surface should be pretty clean. The combined energy is strong at 1542, so there’s some grunt in the water. That said, at 7ft, this is pushing into expert territory—it’s gonna be a bit much for the beginners. Expect crowds here often, so get there early.
Leading up to that, the afternoon of Friday, July 31st shows a 6ft S swell with 14-second period, but the wind is a cross-onshore breeze at 9 mph, which will chop it up a bit. The energy is still strong at 1304, but it won’t be as clean as Saturday morning.
After that peak, the swell drops off fast. By Sunday, August 2nd, we’re down to 5ft and the energy is fading hard to 521. From Monday, August 3rd all the way through to Friday, August 7th, it’s a total write-off. The swell drops to under 3ft, the energy is in the weak 100-300 range, and the wind is either cross-onshore or just plain weak. The surf is just poor. It’s going to be a long, flat week.
So, to sum it up: if you’re keen, point your board at Oceanside Harbor for the dawn patrol on Saturday, August 1st. That’s your one real shot. Everything else is a long wait for nothing.
Rusty.

Information about the Oceanside Harbor Surf forecast
The above surf forecast table for Oceanside Harbor provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Oceanside Harbor can be found by selecting the local surf guide option on the grey menu. Our Oceanside Harbor 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 (Oceanside Harbor) 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 Oceanside Harbor 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.
Oceanside Harbor is 8 km (5 miles) from the city of Oceanside. If you plan a vacation in San Diego County, look for hotels and other accommodation in Oceanside. Oceanside has rooms for a wide range of budgets as well as car hire and transport links.
