The Lowdown
Alright, let’s get real about the next couple of weeks. Look, I’m not gonna sugarcoat it – the surf window we’re looking at is pretty bleak. The models are showing a whole lot of nothing for a while, and it’s gonna be a test of patience. We’re looking at a stretch where the good waves are just not showing up. It’s a long, flat spell, and you might be better off sorting out your gear or finding a skate spot.
We’re starting with a run of poor surf. The swell is small, the winds are mostly onshore or cross-on, and the energy is just weak. The combined energy values are mostly in the 300s and 400s, which is that weak to low-moderate range – not enough to get the blood pumping. The water temp is 76°F with a 8°F anomaly, which is way warmer than normal for this time of year. That’s a nice thing for a swim, but it doesn’t help the waves.
The first real chance of anything rideable shows up around Friday the 14th. The swell is still small, around 2ft to 3ft from the SSW, but the energy ticks up a bit, hitting 572 and 704. It’s still marginal, and the winds are onshore, so it’s not going to be clean. It’s a “maybe” at best. The period is around 18 seconds, which is a long-period groundswell, but with that size and wind, it’s just not going to come together.
The 15th and 16th see a little more size, with the swell pushing to 4ft on Saturday afternoon, but the energy is still moderate and the wind is still on it. The period drops back to 15-16 seconds. It’s still poor. We’re just not getting the right combination.
Honestly, the whole first week is a write-off. We’re looking at a solid 5-6 days of nothing before things even get close to interesting, and even then, it’s just not great.
The second week, from the 17th onward, is more of the same. The swell drops back down to 2ft to 3ft, the periods are in the 13-16 second range, and the winds are mostly onshore or cross-onshore. The energy stays weak to moderate. There’s nothing that stands out as a must-surf session. It’s just a long run of small, messy surf.
So, here’s the bottom line: there are no standout days in this 16-day forecast. The best you can hope for is a marginal, onshore day with a bit of push around the 14th and 15th, but even then, you’re fighting the wind. For a spot like Swamis (North Shore), which needs a good west-northwest swell to really work, this forecast is just a big old dud. The swell direction is from the SSW/SW, which isn't the optimum W direction for the break. The crowds are often there, but with waves this bad, you might have the place to yourself.
If you’re a beginner, the small size is fine, but the conditions are messy. For the more experienced crew, it’s not worth the effort. This is a “check the forecast again tomorrow” kind of situation. A long stretch of nothing is normal for this area in this season, so don’t panic. It’ll come back around.

Information about the Swamis Surf forecast
The above surf forecast table for Swamis provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Swamis can be found by selecting the local surf guide option on the grey menu. Our Swamis 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 (Swamis) 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 Swamis 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.
Swamis is 5 km (3 miles) from the city of Encinitas. If you plan a vacation in San Diego County, look for hotels and other accommodation in Encinitas. Encinitas has rooms for a wide range of budgets as well as car hire and transport links.
