The Lowdown

Alright, Rusty here, let’s break down the Oceanside Harbor outlook.

It’s pretty flat right now and will stay that way for the first few days. The water’s sitting at about 77°, which is much warmer than you’d expect for this time of year – you’ll feel that difference when you hop in.

Nothing worth paddling for on Wednesday the 2nd or Thursday the 3rd. Friday the 4th is still junky, with weak, messy waves that aren’t doing anyone any favors. The energy figures are low through the afternoons.

Saturday the 5th is still small, with a light cross-onshore breeze messing up 4ft swell from the south. It’s not clean, but the wave energy is climbing, so you can see something building.

The real standout is Sunday morning the 6th. That’s your day. We get a clean window early with a light offshore wind from the NNE, and the swell comes in around 6ft from the SSW. The wave energy is strong, and that’s going to give you some proper lines. But heads up – this is a beach/jetty spot exposed to the west, and with a 14-second period, that swell can hit a bit fat and straight. The jetty might be your friend for a better shape. The morning is clean, but by afternoon the wind swings and it gets lumpy.

After Sunday, it’s a slow drop. Monday the 7th looks average with messy cross-onshore wind, and through the rest of the week it goes back to small and weak. There’s a tease on the 8th with 5ft to 6ft swell, but the wind is on it and it’s poor quality. From the 9th onward it’s very small, barely knee-high, with poor surf conditions for days.

The stretch from Monday the 7th through to Wednesday the 16th is a long gap of flat or junk surf. There’s one little flicker on the 17th afternoon, where a small, very long-period swell (21 seconds) shows up, but it’s only borderline and the wind is light cross-onshore. Not something to get excited about.

Bottom line: if you want waves, be in the water early on Sunday the 6th. After that, it’s a waiting game.

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.

Oceanside Harbor is 8 km (5 miles) from the city of Oceanside. If you plan a vacation in San Diego County, look for hotels and other accommodation in Oceanside. Oceanside has rooms for a wide range of budgets as well as car hire and transport links.
