The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Oceanside Harbor over the next couple of weeks.
Honestly, straight up, it’s a bit of a flat and choppy run for most of the period. The ocean’s been pretty quiet. There’s no real clean swell to get excited about for a good stretch. We’ve got a few days of marginal, cross-onshore junk that’s more about getting wet than getting good waves. The first real chance we see of something with a pulse is a bit of a wait – we’re looking at a gap of several days of poor to average conditions before things might change.
For the first week, from Wednesday the 22nd right through the weekend, it’s all about that persistent cross-onshore wind. The swell is there, but it’s messy. The combined energy is moderate – around 500 to 900 (moderate wave energy) – but it’s just not clean. The wind is a real spoiler here. The best of that first week is probably Monday the 27th and Tuesday the 28th. The wind eases off a little, turning more offshore in the mornings, with a 4ft to 4ft SSW swell and a period around 17 to 18 seconds. That’s a proper groundswell, but it’s still a bit lumpy. The combined energy jumps up to 1050 (strong wave energy), so there’s some push, but the quality is questionable.
The one standout, and it’s a long way off, is the Saturday of the 1st of August. That’s the only day that looks like it could be a real session. We’re looking at a 6ft S swell, with a period of 13 seconds, and the combined energy hits 1200 (strong to very strong wave energy). The wind is still cross-on, but it’s a lighter breeze, so it might be clean enough. That’s a bit of solid size for the Harbor, but it’s nothing too crazy. It’s worth keeping an eye on, but it’s a long-range call, so don’t lock it in just yet. After that, it fades back to nothing pretty quickly.
So, for the rarely-consistent Oceanside Harbor, it’s a mostly poor run with one distant, promising Saturday. The water temp is about average for this time of year.
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.

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.
