The Lowdown
Alright folks, Rusty here. Let’s get into it for Atlantida. We’ve got a bit of a slow start, but the second half of the outlook has some real potential.
The week kicks off with a whimper. Thursday the 6th is tiny, with a 2ft swell from the SSE and a period of 9 seconds. The energy is weak (86), and the morning is clean but small. The afternoon goes cross-on and gets worse. Friday the 7th is a write-off – poor conditions all day. Saturday the 8th shows a pulse, but the morning is messy with a 6ft, 13-second SSE swell pumping energy (1118). The wind is a cross-shore, making it a bit of a battle. The real standout on that day is the afternoon. The wind swings to light offshore, and we get a clean 6ft swell from the SSE with a 12-second period and strong energy (871). That’s a solid window of clean, lined-up waves.
Sunday the 9th and Monday the 10th are okay, but not the best. Tuesday the 11th morning is where it starts to get exciting. The wind is light cross-offshore, and we have a 6ft, 12-second SSE swell with very strong energy (900). The waves will be clean and have some punch. If you can get out there, that’s a top pick for the first week.
The middle of the week from Wednesday the 12th to Thursday the 13th morning is a bit mixed, with some cross and cross-on winds. But then, Thursday the 13th afternoon is a gem. The wind goes glassy, the swell is a solid 5ft from the SSE with a 11-second period, and the energy is strong (1012). The conditions are described as excellent for experienced surfers. That’s a session to mark on the calendar for the more advanced crew.
Heading into the second week, Friday the 14th morning is clean with a 5ft, 13-second SSE swell and good energy (628). The weekend gets messy and onshore, so it’s not worth it. The surf fades out completely through the 15th and 16th.
But then, we have a late call. Tuesday the 18th is a winner. The morning is clean with a light cross-offshore wind and a 6ft, 10-second SSE swell with strong energy (788). The afternoon is the same story. Then, on Thursday the 20th, the morning is glassy again with a 6ft, 7-second ENE swell. The period is short, but the clean conditions make it rideable. Finally, on Friday the 21st, we get a 8ft, 8-second ENE swell with a light offshore wind and very good conditions. That’s a long-range standout, but it’s a promising one.
Overall, the water temperature is about normal for this time of year. The best bets are the afternoons of the 8th and 13th, and the mornings of the 11th, 18th, and 21st. Keep an eye on that Friday the 21st.
Rusty.

Information about the Atlantida Surf forecast
The above surf forecast table for Atlantida provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Atlantida can be found by selecting the local surf guide option on the grey menu. Our Atlantida 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 (Atlantida) 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 Atlantida 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.
