The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Honestly, it’s a bit of a slow grind ahead. We’ve got a whole lot of small, weak swell and mostly onshore or cross-onshore wind, so the surf is going to be pretty poor for the vast majority of the 16-day window. The first real flicker of anything rideable doesn’t show up until the middle of the second week, so you’re looking at a long gap of flat or near-flat, messy conditions.

For the first week and a half, from now through to around the 14th of August, the swell is tiny, and the wind is constantly messing it up. The combined wave energy is weak, sitting between 152 and 452 (moderate energy at the top end), but with swell heights barely reaching 3 ft and periods all over the place, it’s just not doing anything for us. The water temperature is about average for this time of year, nothing unusual.

The only time the surf even starts to whisper is on the 14th of August (Friday afternoon) at Oceanside Harbor. The swell ticks up a little, with a 3 ft SSW swell at 18 seconds, and the combined energy jumps to 669 (moderate wave energy). The wind is still onshore, but it’s a light breeze, so it’s not a total washout. The score is still marginal, but it’s the best we’ve seen in a while. This is a super exposed beach/jetty break, so it catches everything, but with that long period (18 seconds), it might be a bit straight and fast for the beach break, but there could be a few fun ones if you pick the right bank.

The 15th of August (Saturday) is a tiny bit better. The morning has a 3 ft SSW swell with a 16-second period, and the combined energy is 571 (moderate). The wind is light onshore, so it’s not clean, but it’s not horrible. The afternoon sees a 4 ft SW swell, again with light cross-onshore wind. This is the biggest swell of the whole period, but it’s still small, and the wind is a factor. For a surfer, it’s the best of a bad bunch, but it’s not a standout.

After that, it drops back down to nothing. The 16th through the 19th are all back to poor surf, tiny waves, and increasing wind. The 17th of August has a moderate breeze from the WNW, making it choppy and ugly.

The best bet: If you’re desperate, the 15th of August (Saturday) is your day. Morning or afternoon, take your pick, but the afternoon has a slightly bigger swell (4 ft from the SW) and the wind is light, so it might be slightly cleaner. The crowds at Oceanside Harbor are often there, so expect some company. It’s an exposed break, so it’s all about finding a bank that works. For a beginner, this is still a bit small, but it’s not dangerous. For an expert, it’s a long wait for a short wave. Just keep your expectations low.

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.
