The Lowdown
Alright, Rusty here again. Let’s break down what’s coming for Swamis.
Right now, it’s looking like a long, slow period ahead. The swell is small and weak for the bulk of the next 16 days, with little to get the heart pumping. Light breezes are common, but mostly onshore or crossing, so the waves are going to be bumpy and crumbly.
From Thursday the 20th of August all the way into late August, the swell is flat and weak – think ankle to waist-high at best, around 2 to 3 ft from the SSW. Periods are mostly between 13 and 14 seconds, so it’s a mix of ground and wind swell with no real energy. The wave energy numbers are low, mostly between 200 and 400. The wind is light from the WSW or SW, often light cross-onshore, so don’t expect clean, peeling waves.
The only real chance of a wave worth paddling for comes late in the forecast. On Sunday the 30th of August, we get a slight pulse: a 4 ft SSW swell with a 15-second period, pushing the combined energy to 657. The wind is light cross-onshore from the WSW at 6 mph, so it’s bumpy but doable. Then Saturday the 29th of August afternoon looks like the best bet – a 4 ft SSW swell with a 16-second period and energy hitting 963. That’s the biggest pulse of the whole window, and with a light breeze at 6 mph from the west, it’ll be glassy and clean.
The water temp is about average for the season, so no surprises there.
So, the only standout session I’d point you to is Swamis on the afternoon of Saturday the 29th of August. It’s a beach-and-reef spot that breaks fairly often, but crowds are a common problem here. The swell will be a long-period 4 ft from the SSW. That long period can make beach breaks straighten out, but the reef structure at Swamis should give the waves a bit of shape. With the light glassy breeze, it’ll be clean. Not a big day, but it’s the only moment in this entire two-week run where the winds and the swell lineup.
For the rest? Honestly, there’s a solid 10-day stretch with nothing worth paddling out for. It’s a quiet spell, but this area can change fast, so keep an eye on the charts. For now, the board stays in the car.
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.
