The Lowdown
Hey, Rusty here. Let’s keep it real – Oceanside Harbor is looking pretty average for the next two weeks. We’ve got a long stretch of tiny waves, one small window of decent size, and then a flat spell. The water is 74°, which is a huge 7° warmer than normal – like swimming in a bathtub.
We start Friday, July 24th, with 2ft SW swell, but the period is a super long 24 seconds, meaning it’s a proper groundswell. The energy is moderate at 928, and with a light onshore breeze, it’s clean but tiny. Not worth the effort.
Saturday the 25th is similar, with 3ft SSW swell, still a long 21-second period. Energy is 910, and the wind is light onshore. You might get a few ankle-biters, but nothing special.
The best window is around Friday, July 31st and Saturday, August 1st. We see a jump to 6ft to 6ft S swell on Friday afternoon, with combined energy of 1352 – that’s moderate. The period drops to 14 seconds, so it’s still a decent groundswell, but the wind is cross-on, so it’ll be a little bumpy. That’s too big for beginners. Saturday the 1st holds around 6ft SSW swell, with 1176 energy, and the wind goes lighter and more onshore. This is your best chance for a decent wave. The break is a beach/jetty, so it can be shifty, and expect crowds.
After that, it’s a slow fade. Sunday the 2nd drops to 4ft, then from Monday the 3rd through Saturday, August 8th, it’s all poor surf. Swell drops to 1ft to 2ft, energy is weak (under 375), and the wind stays cross-on, making it choppy. There’s a long stretch of nothing from the 3rd to the 8th.
If you’re going to pick a day, go for the morning of Saturday, August 1st, when the 6ft SSW swell is cleanest with light onshore winds. It’s not perfect, but it’s the only time the ocean has any real punch.
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.
