The Lowdown
Alright folks, Rusty here. Let's have a look at what’s on the cards for the next couple of weeks.
We’ve got a bit of a quiet start, but there’s a consistent stream of small to modest swell on the horizon. The focus is entirely on Swamis (a beach and reef set-up). The water is sitting at 73°F, which is a very notable 5°F warmer than usual for this time of year – that’s a real treat.
The pattern kicks off on Tuesday, August 25th. Swell is small, around 2ft to 3ft from the SW and S, with a very long 16 second period. The energy is moderate (408–594). The wind is light and offshore in the morning, which is a major positive for clean conditions. This is promising for a longboard or a fun board, but the long period might make it a bit wonky on a beach break. The afternoon gets a touch of cross-on wind, but it’s still light.
Wednesday, August 26th sees a slight bump in size, up to 5ft from the S with a 12 second period. The energy is moderate (888). The cross-on wind is a bit stronger, creating a little chop, so it’s not the cleanest. Thursday, August 27th and Friday, August 28th are similar, with smaller waves (2ft–4ft) and mostly light offshore winds, keeping things tidy. The standout period of the first week is actually the Saturday, August 29th and Sunday, August 30th. Swell hangs around 4ft–4ft from the SSW, with a long 16 second period and moderate energy (790–862). The wind is offshore in the afternoon, making for some clean, if slightly long-period, waves. This is your best bet for the first week.
The second week gets a bit more mixed. Monday, August 31st through to Wednesday, September 2nd offer small, clean waves (3ft–3ft) with light offshore winds, but the energy is weak. Thursday, September 3rd has a small pulse of 3ft from the SSW with a very long 18 second period and moderate energy (696). The best of the second week looks to be on Friday, September 4th and Saturday, September 5th. Swell picks up to 4ft from the SSW, with a 17 second period and good energy (702–778). The wind is light and cross-onshore, but it’s manageable. This is a promising, but less certain, window.
After that, the energy drops off significantly. From Sunday, September 6th through to Wednesday, September 9th, it’s mainly small, weak waves (2ft–4ft) and the conditions are often poor or marginal. The swell is there, but it’s not really worth getting excited about.
Overall, the best sessions are likely to be the Saturday August 29th/Sunday August 30th and the Friday September 4th/Saturday September 5th. The swell is small, so it’s perfect for a longboard, but the long periods mean the point and reef at Swamis should handle it better than a straight beach. Don't expect a huge, powerful session, but there will be clean, fun waves to be had.
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.
