The Lowdown
Alright folks, Rusty here. Let’s have a look at the next few weeks at Swamis. It’s a bit of a mixed bag, but I’ll walk you through it.
The forecast period kicks off now, but honestly, there’s no real surf to get excited about for the first while. We’re looking at a long stretch of weak, small waves and poor conditions. From Tuesday the 18th of August through to the end of the month, most days offer nothing worth paddling out for. The swell is hanging around 2 ft to 3 ft, with a lot of it coming from the SSW, and the wind is mostly cross-onshore, leaving the surface bumpy and messy. The combined energy is weak, hovering around 200 to 475 (weak to moderate energy), so it’s really just a lot of groveling if you’re desperate. Don’t bother.
There’s a gap right through until the start of September where the surf is just not good. The water temperature is about average for this time of year, nothing out of the ordinary.
Now, the only real glimmer of hope in this whole outlook comes right at the end of the period. On Saturday the 29th of August, the swell picks up a bit, with a wave height of 3 ft to 4 ft from the SSW, and the period stretches out to 18 seconds – that’s a proper groundswell. The combined energy jumps to 816 (moderate energy), which is a noticeable step up. The wind is light cross-onshore, but it’s still manageable. This is your best shot, but it’s still only marginal, with questionable tide conditions. It’s not a classic, but it’s the only real pulse in the forecast.
For the advanced crew, Swamis is a fairly consistent spot, but it rarely gets a proper clean run. On that Saturday, the long-period swell (18 seconds) means it’ll be a bit more lined up, but it’s a beach-and-reef setup, so don’t expect perfection. The crowds are often there, so you’ll have company. This is the standout, but it’s a promise with a lot of uncertainty this far out. The combined energy (816) is the best we’ve got.
After that, Monday the 31st of August and Tuesday the 1st of September drop back into the doldrums, with small, weak swell and poor conditions. There’s nothing else to recommend.
So, to sum it up: the next couple of weeks are mostly a write-off for Swamis. The only real option is the late August swell, which is worth a look for the committed, but don’t expect epic perfection. Keep your eyes on the sky, because the forecast can change.
Rusty.

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.
