The Lowdown
Alright, Rusty here. Let’s take a look at what’s brewing for our local waters.
The next 16 days are a bit of a mixed bag, to be honest. We’ve got a slow start, but there’s a pulse of energy building towards the first weekend. Overall, we’re looking at a lot of marginal or poor conditions, so don’t get your hopes up too high, but there are a couple of windows worth paddling out for.
We kick off with a blank period. From Wednesday the 2nd right through to Thursday the 4th, the surf is poor. The swell is tiny and the wind is messy. Honestly, it’s not worth getting the board wet.
Friday the 4th morning sees a slight uptick, with a 3 ft SSW swell rolling in. The combined energy is moderate at 623, but the wind is a cross-on from the SW, making it choppy. It’s still marginal, a real “maybe” for a desperate surfer. The afternoon looks better size-wise, with 4 ft from the SSW, but the onshore wind (W at 15 km/h) will keep things raggedy.
Saturday the 5th is where things get a bit more interesting. The swell builds to 4 ft from the S, with a period of 14 seconds, giving it some decent grunt. The combined energy jumps to 1310, which is strong. But, the wind is onshore from the WSW (5 km/h) and it’s cloudy. The score is a 3, which is the best we’ve seen so far, but still marginal. It’s a “keep an eye on it” morning. The afternoon is similar but a touch smaller.
Sunday the 6th is the standout. This is the one to circle on the calendar. The swell hits 7 ft from the S, with a period of 14 seconds. The combined energy is a solid 1630. The wind shifts to a cross-shore from the N (15 km/h), which will clean things up nicely. This is a proper long-period groundswell, so the waves will have good shape and plenty of energy. The troughs between sets will be longer, making the paddle out easier. For a spot like Swamis (a beach and reef setup), this is a quality window. The morning is the better call. The afternoon sees the wind go a little cross-on from the NW, but still manageable. This is the best of the 16 days, but remember, *7 ft* is getting solid. It’s more for the advanced crew, and the crowds are likely to be around.
Monday the 7th holds some size, with 6 ft of SSW swell in the morning, but the wind is back onshore from the W. The energy is still strong (1131), but the quality drops. The afternoon is poor.
From Tuesday the 8th onwards, the trend is downward. The swell drops off, and the wind remains onshore or cross-on for most of the remaining days. The period stays decent in the first few days, but the size fades. By the middle of the second week, from about Friday the 12th on, the swell is consistently under 3 ft, and the wind is still a problem. The energy drops into the hundreds (200-500 range), which is weak. There’s a little blip on Thursday the 17th with a moderate energy reading of 786, but the swell is only 3 ft. It’s still a marginal call.
So, to sum it up: the first few days are a write-off. Sunday the 6th is the clear winner, with a solid 7 ft S groundswell and clean cross-shore winds. Saturday the 5th is a backup, but it’s onshore. The rest of the window is mostly for the die-hards or those just wanting a paddle.
Signing off, 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.
