The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for the next couple of weeks.
Right off the bat, we’ve got some solid, consistent swell rolling in, but it’s a bit of a mixed bag with the wind. We’re looking at a stretch that starts up Saturday morning and runs through to the following Saturday, with a real standout on the Friday the 31st of July. The water temp is sitting at 72°F, which is a massive 5°F warmer than normal for this time of year – that’s a real treat, almost like bath water.
We’ll kick things off at Oceanside Harbor (Oceanside-Harbor). This is an exposed beach/jetty spot, and it’s very consistent. It’s an advanced wave, so not one for the groms. Saturday morning the 25th sees a clean 3ft SSW swell with a very long 21-second period. The wind is light and onshore from the SW, but the energy is moderate (911). Saturday afternoon, the swell shifts a touch to the SW, same size, period drops to 21 seconds, and the energy eases a bit (708). Sunday the 26th builds slightly to 4ft from the SW, period 19 seconds, with light onshore wind. The energy is still moderate (938 in the morning, 801 in the afternoon). Monday the 27th is a step up with 4ft from the SSW, period 18 seconds, and the energy is pushing into strong territory at 1150 in the morning. Still light, onshore winds.
Tuesday the 28th gets a little messier. The swell holds at 4ft from the SSW, period 17 seconds, but the wind picks up to 9 mph from the SSW, going cross-onshore, which will put a bit of a chop on the surface. The energy is still strong (1020-1068), but the quality takes a hit. Wednesday the 29th is similar, with the swell dipping a touch to 4ft and the period down to 16 seconds. The wind stays onshore or cross-onshore, keeping things a bit lumpy. Thursday the 30th is where it starts to get interesting. The swell direction swings to the S, and the height jumps to 4ft in the morning with a 15-second period, then 6ft in the afternoon with a 14-second period. The energy is strong (1110 in the morning, 1374 in the afternoon). The wind is light and onshore, so the surface stays clean.
Now, Friday the 31st of July is the standout. We’ve got a solid 7ft swell from the S in the morning, with a 14-second period. The combined energy is a beefy 1640, which is strong. The wind is a gentle cross-onshore from the WSW at 9 mph, which is a bit of a bummer, but the size and power are there. This is a big, powerful groundswell that will be better suited to the jetty itself than the beach. It’s a bit heavy for the average surfer, but for the experts out there, this is the session to circle. The crowd profile here is “often” busy, so expect company.
Saturday the 1st of August starts to fade. The swell drops to 6ft from the SSW, period 13 seconds, with light onshore wind. The energy is still moderate (946). By Sunday the 2nd of August, it’s all over. The swell crashes to 3ft, period 10 seconds, and the energy is weak (305). The forecast then goes into a long, flat spell with poor surf conditions. From the 2nd of August through to the 9th of August, we’re looking at a solid week of nothing worth paddling out for. The swell is tiny, mostly under 2ft, with short periods and weak energy. The wind stays light, but there’s just no wave energy to work with. The 9th of August has a faint pulse of 2ft from the SSW with a 17-second period, but the energy is only 364 and the wind is cross-onshore, so it’s still a no-go.
So, the takeaway: get on it this weekend and next week, with Friday the 31st of July being the real gem. After that, it’s a long, flat stretch until the 9th of August, which is just a tease.
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.
