The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s on the table for the next couple of weeks. The first real chance to get wet isn’t until Saturday the 6th, so there’s a dead gap of nothing rideable from now until then. The early part of the week is just a mix of small, messy, cross-shore junk that’s not worth paddling out for.
The first sniff of decent surf shows up Sunday morning the 6th at Atlantida (beach/pier). It’s a bit of a raw one – 6ft of S swell at 9 seconds, with a cross-offshore breeze from the W at 16 mph. The water’s clean, and the combined energy is moderate (566). The wind is ripping a bit, but it’s offshore, so the face should be groomed. Sunday afternoon gets chunkier with 8ft S swell, but the wind stays cross-off, and the energy jumps to strong (1735). That’s getting into the heavy zone, so only for the experienced crew.
Monday morning the 7th is a good shout – 5ft SSE swell, 9 seconds, with a light WSW cross-off breeze at 6 mph. The water’s clean, energy is moderate (348), and it should be a fun, manageable size for intermediates. The direction is a bit off the optimum for this break, but it’s still workable.
The real standout, though, is Monday the 14th. That morning, the stars align for the experienced surfer. We’ve got 7ft of ESE swell, 11 seconds – that’s a proper groundswell, long period, meaning better shaped waves and more power. The wind is dead glassy, calm as a lake, and the energy is strong (1332). The swell direction (ESE) is not the absolute optimum, but with that glassy surface and solid height, it’s going to be firing. The wave comment says “excellent surf conditions for experienced surfers,” and I’m backing that. This is the best on offer in the whole window. The afternoon drops to 7ft, but the wind swings cross-on, so get your session in early.
Tuesday the 15th morning is another solid option – 5ft ESE swell, 11 seconds, cross-off from the WSW at 9 mph, clean, with strong energy (720). It’s a step down from Monday, but still a very good day.
Late in the run, Saturday the 19th morning is worth a mention. Glassy conditions again, with 8ft ENE swell, 8 seconds. The period is short, so it’s windswell, but the energy is strong (700), and the calm wind means it’ll be as clean as a whistle. That’s a good one for the weekend warriors.
Crowds: Atlantida is often crowded, so expect company, especially on the weekend mornings. Consistency: The break is inconsistent, so when it’s on, it’s worth making the call.
Water temp: The water is 62°F, which is about average for the time of year, so a 3/2 wetsuit is the go-to.
Bottom line: The best day without a doubt is Monday the 14th – glassy, solid groundswell, clean. The second best is Saturday the 19th morning – glassy and decent size. Everything else is either too small, too messy, or too big for the average punter.
Catch ya out there,
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.
