Rusty here again, let’s talk about what’s happening at Oceanside Harbor in feet and degrees.
Right off the bat, the water is a touch warmer than usual for this time of year — about 69°F, which is roughly 2°F above normal, so it’s a little nicer on the skin.
Real talk: there’s not much to get stoked about over the whole 16-day run. The swell energy is light to moderate, with combined energy numbers sitting between 608 and 400 in the first week, then droppin’ into the weak range under 300 later on. It’s a long-period groundswell, mostly 16 to 18 seconds between sets, so the waves have some push and shape, but at a beach-and-jetty spot like this, that long period makes ’em run too straight for good turns. Oceanside Harbor is very consistent and exposed, so it catches whatever is out there, but that isn’t much — waves are 2 to 3 ft at best, and the wind is almost always cross-on from the W or SW, keeping the surface chopped up.
The closest thing to a highlight is Tuesday morning, July 7th, with 4 ft swell from the SSW and an 18-second period, but it’s blown out by onshore wind from the SW at 10 km/h (about 6 mph). Not clean. After that, from Friday, July 10th into the second week, the swell drops to 3 ft, then 2 ft, and smaller, with energy falling off a cliff. Wind stays cross-on or onshore, light but never glassy.
By the time we hit Monday, July 13th and beyond, the waves are little ankle-slappers — 1 ft to 2 ft — with long waits between sets. For beginners, anything over 5 ft is too big, but here it’s the opposite — it’s all too small to be fun for anyone but a longboarder with zero expectations.
Crowds are often, so you’ll have company even on these flat days. There’s no true standout in this run. If you had to pick a session, Wednesday afternoon, July 8th might be the least bad — light cross-on wind from the WSW at 6 mph, 4 ft swell from the SSW at 16 seconds, and moderate energy (714). Still just marginal.
Bottom line: you’re looking at a real flat spell here. No juice, messy wind, and the quality never turns on. This is one of those quiet stretches for Oceanside Harbor — it won’t stay this way forever, but right now it’s a waiting game.
Keep the wax dry,
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.
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.
