The Lowdown
Alright, Rusty here again. Let's break it down for those who think in feet and miles.
So we've got a solid run of surf on the menu for the next couple of weeks, but it's a slow burn. Don't expect perfection every day. Water temp is a balmy 79.9°, right where it should be, so you won't be needing a steamer.
The first chance to get wet is Thursday, September 3rd. It's a bit marginal, with a 5-foot SSW swell coming from a deep, 16-second period groundswell. The energy is moderate (1041), but that 16 mph SE cross-off wind is going to mess with the surface. It's a paddle-out, not a photo-shoot.
That story pretty much sticks for the next week. The swell hangs around from the SSW, building to over 7 feet by Monday the 7th, but we're stuck with that same cross-off wind at 12 to 16 mph. The power builds, hitting a strong 2136 by Sunday morning, but the surface stays bumpy.
The wind eases a bit on Wednesday the 9th morning, dropping to 9 mph with a bigger 8-foot SSW swell, and the energy is strong (3244). Come afternoon, the wind shifts more cross-shore, putting a bit of a chop on things. Still not the one.
The real gem is Friday, September 18th. The Friday morning session is the one to circle on your calendar, but it's for experts only. The swell holds at a solid 8 feet from the SSW with a 17-second period, and it's packing serious heat—strong energy (3700). The wind finally plays ball, dropping to a gentle 9 mph ESE breeze. That will give us the cleanest, most lined-up waves of the whole stretch. That long period will mean longer waits between sets, but the shape should be killer.
The early stuff is just filling the time. Get your schedule clear for the 18th. That's the day that's got me excited.

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 Ekas-Inside 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.
