The Lowdown
Alright, Rusty here with the outlook for Swamis.
Honestly, looking at the whole 16-day window, it’s a bit of a tough stretch. We’ve got some very long-period swell lines rolling in, but the wind is working against us most of the time, keeping things messy. The water temp is sitting right around average for this time of year, nothing crazy there.
The first real chance to get wet is on the morning of Thursday the 13th. Swells from the SW are around 2ft with a super long 16-second period, pushing the combined swell energy to 330 (moderate). The wind is a light cross-onshore at 6 mph from the WSW, which is creating some small wind ripples. It’s not great, but it’s rideable if you’re keen. The afternoon stays similar but slightly bigger at 3ft, though the wind picks up and goes straight onshore, making things poor. This tough pattern pretty much locks in through the 14th and 15th. The wave energy actually climbs into the 700s (strong) on the 14th afternoon and 15th afternoon with swell around 3-4ft from the SSW, but that onshore wind from the W at 9 mph just kills the quality.
That long-period groundswell (16-18 seconds) has good energy behind it, but at a beach-and-reef setup like Swamis, those long lines can break a bit straight. So even though there’s push, the conditions aren’t doing us any favours. Saturday the 16th through Monday the 18th is more of the same – onshore wind, poor conditions, and dropping swell from 3ft down to 2ft. It’s a real frustrating run.
From Tuesday the 19th through to the end of the period on the 28th, we’re stuck in a rut. Swell sizes hover between 2ft and 3ft, mostly from the SSW or SW, with periods still decent (13-19 seconds), so the energy is there, but the wind is either onshore or cross-onshore from the WSW or SW at 6-9 mph. The wave energy stays moderate in the 200s to 400s, but every single time slot is listed as “poor surf conditions” or “marginal.” There’s no standout session here.
If the wind ever goes light and offshore, the swell is long and clean enough to be fun, but as it stands, it’s a period best left for checking the forecast every morning hoping for a change. For now, the kite surfers might find the cross-onshore winds more interesting than paddle surfers.
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.
