The Lowdown

Alright folks, Rusty here. Let's have a look at what we've got cooking for Oceanside Harbor.

Right off the bat, it’s a tough stretch. The surf is small, the wind is messy, and honestly, for the next week and a half or so, there’s nothing that gets me properly excited. The first real week is a write-off with poor conditions and tiny waves, so you might as well save the wax. We’re looking at a pretty long gap with no real recommendations.

The water is running about 72°, which is much warmer than normal for this time of year – that’s a nice surprise for a paddle.

We finally see a bit of a pulse rolling in around Thursday, 4th September. The morning sees some SSW swell building to 4 ft, with a period of 18 seconds. That’s proper groundswell energy, showing a combined energy of 1143 (moderate to strong). This is a long-period swell, so it’s going to wrap in with some real push, and it could be a bit straight for a beach setup, but the jetty might focus it up nicely. The wind is a light onshore from the SSW, which is cross-on at 9 mph – it’s not perfect, but it's light enough that the shape should hold. This is the standout window: Thursday 4th September morning, with the afternoon staying around 4 ft and cleaner cross-on wind from the WSW at 6 mph. The Friday and Saturday that follow hold similar size but with more cross-on wind, so it’s not quite as clean.

Overall, the first week is a dud. The standout is that Thursday the 4th, but remember, this is a long-range call, so it’s promising but not locked in yet.

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.
