Table - best surf conditions forecast for Oceanside Harbor over the next 16 days.
Alright folks, Rusty here. Let’s get straight into what’s cookin’ for the next couple of weeks.
First up, I gotta be straight with you – the start of this period is a tough one. We’re lookin’ at a solid run of poor surf conditions through to the middle of next week. The swell is tiny, and we’ve got a persistent cross-onshore wind messing things up. The water is sittin’ at 71°, which is a solid 4° warmer than usual for this time of year – feels like a bath out there, but that’s about the only perk.
We’ve got a long gap of basically nothing worth paddling out for until Saturday, July 18th. That’s when we finally see a pulse of energy. The waves bump up to about 4ft, with a 13-second period from the S, and the combined energy reads 790 – that’s moderate, but it’s still a bit on the messy side. The wind is still cross-on from the W at 9 mph, so it’s not going to be perfect.
The real standout, if you can wait, is Saturday afternoon, July 18th. The swell is 5ft from the S, period at 14 seconds, and the energy jumps to 1080 – that’s a solid, moderate punch. It’s still got that cross-onshore wind, but it’s light. This is the best chance for a wave all week, but it’s not a clean day.
Looking further out, the swell builds a bit more around Wednesday, July 22nd. The afternoon brings a 4ft S swell with a 15-second period, and the energy hits 1071. The wind goes light and onshore, so it’s clean but the swell is a bit chunky. For the advanced crew, there’s a stretch on July 23rd and 24th with the swell hitting 5ft to 6ft from the S, but the period drops to 13-14 seconds, and the wind is still cross-on. The energy is there (1131 on the 23rd), but the quality is marginal. That size is getting into expert-only territory, and the beach/jetty setup at Oceanside Harbor means it’ll be a bit of a battle.
Honestly, folks, there’s nothing here that’s truly firing. The best we’ve got is the Saturday the 18th afternoon, and even that’s a “maybe” if you’re keen. The rest is a waiting game. For the second week, the pattern doesn’t change much – small to moderate swell, persistent cross-on wind, and mostly marginal conditions. If you’re a kite surfer, the stronger wind days on the 21st and 23rd might be more your thing than paddling.
Keep your eyes on the charts, but don’t hold your breath.
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.
