The Lowdown
Alright, Rusty here. Let’s break down what’s coming.
We’re starting off pretty flat. The first few days are a total loss for Swamis – just a tiny 2ft swell with cross-onshore wind making a mess of things. The water is running much warmer than usual at 73°, which is a weird bonus, but doesn’t help the waves. There’s a long stretch of poor to marginal surf through the first week, with the combined energy starting weak and slowly climbing. The real action doesn’t get going until the weekend.
Sunday, July 19th is the first real pulse. The swell picks up to 3ft from the SW, but the wind is onshore. The combined energy hits 1047 (moderate energy) and the period is a solid 17 seconds – that’s a nice long groundswell for a reef point. It’s still only marginal, but it’s the first time the ocean has any real shape. The onshore breeze keeps it from being a standout, though.
The time to really circle on the calendar is late July. From Monday, July 27th, the swell sits at 4ft to 5ft from the SSW, with periods of 18 to 19 seconds – that’s very long period groundswell. This is the energy that will wrap into Swamis nicely, especially since the swell direction lines up with the optimum west swell. The combined energy is strong at 1467 to 1642, the biggest push of the whole 16 days. The wind is mostly onshore or a gentle cross-offshore, so it’s not glassy, but it’s powerful. For an advanced, fairly consistent spot, this is the best window. Crowds are often here, so you’ll have company.
One more thing: Friday, July 31st, the swell jumps to 7ft from the S – that’s expert territory, especially with onshore winds. Not a day for the average surfer. And by August 1st, it’s dropping back down.
So, the first week is a wash. The second week builds nicely, and the real standout is that late July window from the 27th to the 29th – bigger, long-period swell with strong energy. Not perfect, but the best on offer by a long shot.
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.
