The Lowdown
Right off the bat, we’ve got a bit of a slow stretch here. The first few days are pretty gutless, with tiny, chopped-up surf and onshore winds. It’s going to be a bit of a grind just to find anything rideable, so don’t expect much until we get a little further down the line.
Tuesday the 15th is a write-off, mate. We’re looking at a 2ft swell with a 16-second period, but the wind is messing it up. Gentle cross-onshore breeze and fairly choppy conditions mean it’s not worth the paddle. The combined energy is weak as well – 274. Not a lot to work with.
Wednesday the 16th isn’t much better. Still small, that 3ft SSW swell, but the energy ticks up a bit to 515. The problem is the light cross-onshore wind is kicking up small ripples, so it’s marginal at best. You might find a few crumbly ones, but it’s a tough ask.
We head into Thursday and Friday, the 17th and 18th, and it’s still pretty flat and grovelly. Swell hangs around 2ft to 3ft, and the winds are straight onshore. The energy is moderate – 457 to 499 – but with the onshores, it’s just messy. Not the kind of surf that gets you excited.
Now, things start to get a little more interesting heading into the weekend. Saturday the 19th and Sunday the 20th, the swell pushes up to 3ft to 3ft, but the period is still long, around 18 seconds. The energy is building – 552 and then up to 655 – so there’s more push behind it. The winds are light cross-onshore, which helps clean it up a touch. It’s still only marginal, but you might snag a few on the sets. Not a standout, but at least it’s not a total loss.
Monday the 21st sees the swell nudge up to 3ft to 4ft, and the energy is solid at 675 to 717. But the wind swings onshore again, which keeps the quality down. It’s marginal, so if you’re keen, you’ll be fighting the bumps.
The middle of the week, the 22nd and 23rd, we back off again. Swell drops to 3ft, the winds are onshore, and the energy fades to the 400s. It’s poor, mate. Not really worth the effort unless you’re desperate for a paddle.
Thursday the 24th and Friday the 25th, we’re still in the doldrums. 3ft of swell, but the period drops to 13-14 seconds, and the energy falls to the low 300s. Wind is onshore. Everything is telling me to stay on the beach.
We go into the final weekend, the 26th and 27th, and it’s much of the same. Swell around 2ft to 3ft, period dropping to 12-13 seconds, energy down in the 230s to 340s. It’s weak and messy. Not a lot of hope.
But then, look at the end of the window. Monday the 28th and Tuesday the 29th, we get a slight pulse – 3ft, then 3ft, but the period holds at 12-17 seconds. The energy is moderate, around 389 to 453. Still onshore winds though, so it’s not clean.
The one thing that stands out is the last day, Wednesday the 30th. We get a 4ft swell from the W, but the period is only 8 seconds – that’s short period windswell. The energy is back up to 408, but that short period tends to be jumbled and won’t have much shape. Light cross-onshore breeze, but still not great.
Look, if I’m calling it, there’s no true standout in this whole 16 days. The biggest pulse is that 4ft at the very end, but with that short period it’s not going to be anything special. The most consistent energy is around the 19th to the 21st, but even that is only marginal. You’ll be scratching for waves. It’s a lean spell, so don’t be afraid to save your energy for a better run down the track.
Keep an eye on that last day, Wednesday the 30th, but don’t hold your breath.

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.
