The Lowdown
Alright, let's be real with you. The next couple of weeks at Swamis are looking flat and frustrating. It's a tough stretch with not much to get excited about.
We start off right away with nothing doing. Thursday the 10th and Friday the 11th are straight-up write-offs. The swell is small, around 3ft from the southwest, but a 17-second period suggests some deepwater energy. The problem is the wind is a messy cross-onshore, making it choppy and bumpy. It's going to be a frustrating paddle for barely any reward.
That trend holds through the weekend. Saturday the 12th and Sunday the 13th are even smaller, with swell dropping to 3ft and 2ft. The wind stays onshore, and the energy is weak (combined energy around 300). Monday the 14th through Tuesday the 15th doesn't get any better. It's the same story: small, weak swell with a constant onshore breeze. Honestly, it's more of a kite-surfing scenario than a paddle-surfing one. We’re looking at a solid week of nothing.
There’s a slight flicker of hope around Wednesday the 16th and Thursday the 17th. The swell holds around 3ft, but more importantly, the wind turns offshore. That’s a glassy, clean setup and a big positive. The period is still long, in the 17-second range, which at a beach-and-reef setup like Swamis might be a little straight, but with offshore wind, it's worth a look. The energy is still moderate (500-600), so you won't be blown off your board.
The best bet in this whole outlook looks to be the weekend of the 19th and 20th of September. Saturday morning the 19th has a clean 3ft southwest swell with light offshore wind. Sunday the 20th sees a slight bump in energy (combined energy up to 732) with a clean cross-shore wind. It's not pumping, but the conditions will be a lot better than what we’ve been dealing with. It’ll be small, but clean.
After that, we go into another patch of poor conditions. Monday the 22nd and Tuesday the 23rd see the wind go onshore again and the swell stays small. Then Wednesday the 24th and Thursday the 25th bring stronger, messier winds from the south and light rain. It’s a choppy, grovelly end to the forecast.
To sum it up: the first week is a loss. The best windows are the mornings of the 16th, 17th, 19th, and 20th when the wind goes offshore. The 20th looks like the standout, with the most energy and a cross-shore wind. It’s not going to be big, but it’ll be clean.

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.
