The Lowdown
Alright, grab your wettie, let’s talk about what’s on offer at Oceanside Harbor for the next couple of weeks.
Honestly, the outlook is a bit of a flat spell. We’ve got a solid run of small, weak swell coming in, but the wind is mostly going to be on it, which is going to keep things messy. For the first few days, we’re looking at ankle to knee-high lines, maybe 2ft to 2ft, with a short period. That’s not really doing much for us. The energy is weak, too, with values mostly in the 120 to 213 range, which tells you there’s just not a lot of push behind it. Monday and Tuesday are a write-off for any real surfing; you’ll be fighting the chop more than riding a wave.
Things start to look a little more interesting from Friday the 7th onwards. There’s a bit of a bump in the energy, climbing into the 300s and 400s, and the swell gets a touch more size, up to 2ft to 3ft. The period also jumps to 17-19 seconds, which is long-period groundswell, promising better shape and more power. Still, the wind is mostly onshore or cross-onshore, so the surface isn't going to be clean. Saturday the 8th is probably the pick of this first run, with a little more size and a period of 17 seconds, but even that is a marginal call at best. It’s not going to be a classic.
The following week, from Monday the 10th onward, the swell drops back down again, but the period stays long. The size is consistently small, around 2ft to 2ft, and the energy is moderate at best. The wind is mostly light, but it’s cross-onshore, so there will be some texture on the surface. There’s a brief lift in energy around Friday the 14th and Saturday the 15th, with the swell pushing back up to 3ft and the period staying around 16 seconds. But again, that’s still not big, and the wind remains an issue. The waves will be breaking, but it’s a far cry from a standout day.
The water temperature here is about average for this time of year, so you won’t need a full winter suit, but a spring suit might be your go-to.
So, with this all in mind, there's no real standout day. The best of a pretty average bunch is probably the morning of Saturday the 8th, with that 3ft of SSW swell and 17-second period. It's still small, but the energy is there and the wind is a little lighter than the rest. Don’t get too excited about it, but if you’re desperate, that’s your window. The rest is a lot of paddling for not much reward.

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.
