The Lowdown
Alright folks, Rusty here. Let's have a look at what Oceanside Harbor has in store for us over the next couple of weeks.
Right off the bat, we've got a bit of a slow start. The surf is pretty marginal through Saturday, so don't expect much. The water is sitting at a warm 74°, which is a solid 6° warmer than usual for this time of year—that’s really unusual, so a spring suit or just a rash guard will be all you need.
The first real window of opportunity opens up on Sunday, September 6th. That morning, we’re looking at the standout session of the entire forecast. A clean 6ft south swell is rolling in with a 14-second period, giving it some decent grunt. The combined energy is moderate at 1272, and the real kicker is the offshore NNE breeze at 9 mph. That’ll keep the faces clean and make for some proper shaped waves. This is advanced territory, though—that 6ft is getting up there, and the jetty can throw some tricky sections. It’s very consistent here, so expect plenty of waves, but also expect the crowds to be likely given it’s a known spot. This is your best bet, hands down. The afternoon holds up with a similar 5ft south swell, just with a cross-off breeze, still clean and good fun.
Monday the 7th sees the swell size bump up a touch to 6ft from the SSW, but the wind swings cross-on from the WNW, chopping things up and making it messy. The quality drops off hard, and the energy is still moderate at 1272, but it’s just not worth it with that wind. Things go downhill from there.
From Tuesday the 8th all the way through the end of the forecast on September 20th, it’s a long stretch of poor to marginal surf. The swell drops off significantly, hanging around 1ft to 3ft with mostly weak energy readings—sometimes dipping below 300, which is barely a ripple. The winds are mostly light and cross-on or onshore, and while there are a few moments of clean conditions, the lack of any real size or power means there’s nothing to get excited about. There's a long gap of over a week with no real recommendations. If you’re desperate, the small windows on Wednesday the 9th or Thursday the 10th have some waist-high SW swell with light onshore wind, but it’s marginal at best. Honestly, with the swell so small and the wind being mostly cross-on, the setup at this beach/jetty looks more interesting for kite surfing than paddle surfing during that stretch.
So to sum it up: Sunday morning, September 6th is your day. Get on it while you can, because after that, it’s a long wait for the next real pulse.
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.
