The Lowdown

Alright, Rusty here. Let's talk about what's cookin' at Oceanside Harbor.

Right off the bat, the water is *much* warmer than normal for this time of year, a solid 72.3°F with a massive anomaly pushing nearly 5.4°F. That feels like bathwater, a real treat.

Now, the surf. Honestly, it's a bit of a mixed bag. For the last week of July, there's some consistent, rideable swell – nothing huge, but enough to get wet. The main issue is that for most of these sessions, the forecast is calling it 'marginal', with a few question marks over the tide. The combined swell energy sits between 708 and 1132 for those afternoon sessions, so that's moderate wave energy going on there. The swell is coming from the SW and SSW with long periods, well over 15 seconds at first. That long-period groundswell will wrap in and give you some nice lines, but at a beach/jetty spot, the sets will be long and spaced out, making it easier to get out the back.

A standout window shapes up from the afternoon of Thursday, July 30th, into Friday, July 31st. On Thursday afternoon, we see the height bump to 5.6ft from the S, with a light WSW breeze keeping things clean. The energy jumps up to 1128. Friday morning pushes that a bit further to 6.2ft from the SSW with that same light offshore wind, and a very strong combined energy of 1395. Friday is the real deal, but at that size, it's getting into expert territory for sure. The wind looks mostly light and offshore all week, which is a huge positive for keeping the surface smooth.

But then the wheels fall off. From Sunday, August 2nd, everything just drops away. For a solid week, through to August 9th, the heights are tiny, 2.6ft and below, with poor surf conditions and zero scores. This is a proper flat spell. The energy readings sink to the low hundreds, and the whole thing just goes quiet. There's a long gap with nothing worth paddling for.

So, here's the call: If you've got a short board and you're looking for a long-period swell that's clean but a bit on the bigger side, the best bet in this window is Friday, July 31st at Oceanside Harbor. The morning looks best with 6.2ft SSW swell and a light offshore wind. It’s the standout, but it's only for the more experienced crew.

Stay stoked, and keep an eye on the charts. This blank run is a bummer but it's just how it goes sometimes.

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.
