The Lowdown
Alright folks, Rusty here with the lowdown for E-Bay. This reef spot’s about to see a real nice run of south swell over the next couple weeks, and I’ve got my eye on a few special sessions.
The action kicks off this afternoon, Monday the 3rd of August, with a south swell running about 3 ft on a real long 14-second interval. Combined energy sits at 776 – decent for a warm-up. Wind’s from the west at 9 mph, cross-offshore, so it’s clean but not the main event.
Tuesday the 4th gets more interesting. Morning sees 4 ft of south swell, still with that long 16-second period, and a north wind at 12 mph blowing offshore. Clean lines and fun energy. The afternoon bumps to 4 ft with energy at 866. Both sessions are good – I’m liking this.
Wednesday the 5th is where it gets sweet. Swell swings to the SSW at 4 to 4 ft, long period of 15 seconds. Wednesday morning has offshore north wind at 12 mph, but Wednesday afternoon is a gem – wind drops to 6 mph offshore, and combined energy jumps to a very solid 1294. Clean, glassy conditions on a reef. That’s a window to circle.
Thursday the 6th brings 5 ft of south swell at 17 seconds – combined energy of 1489. Morning wind is offshore from the northwest at 16 mph, making for excellent but more powerful waves. This one’s for experienced surfers only.
Friday the 7th and Saturday the 8th are the best of the whole run. Friday morning: 6 ft from the south, 18 seconds, combined energy of 2174. Wind is cross-offshore from the NNE at 12 mph, clean enough. Then Friday afternoon: 6 ft, 17-second period, combined energy of 2263, and offshore north wind at 12 mph. That’s pumping. Saturday morning holds 6 ft at 16 seconds with a gentle 9 mph north offshore. Combined energy is 1694 and the breeze is so light it’s almost glassy. This is the one.
Sunday the 9th the quality fades. Swell holds at 5 to 6 ft, but the wind turns onshore from the southeast by the afternoon. It’s surfable but not what it was.
Monday the 10th through Tuesday the 11th the wind goes full onshore from the SSE, blowing 16 mph as the swell builds to 7 ft. Combined energy hits 3556, but it’s blown-out and messy. Kite-surfing conditions, not for paddlers.
From Wednesday the 12th right through to Monday the 17th, we’re stuck with onshore winds from the southeast or south-southeast. Swell ranges from 4 ft to 7 ft, but the wind direction kills it for that reef. A few lighter wind windows, but nothing to write home about.
Finally, Tuesday the 18th has the swell back near 7 ft with onshore SSE winds at 12 to 16 mph. Combined energy is a huge 3000, but it’s poor – another kite day.
Your best shots are Friday afternoon the 7th and Saturday morning the 8th. That’s the sweet spot: big, clean, offshore wind, and long-period groundswell. E-Bay is a reef, so expect lined-up waves, but that long period can make it wall up – it’ll be rippable. Crowds can show when it’s this good, so bring your patience. Water temp sits at about 85°F, which is a touch warmer than usual for this time of year – real pleasant.
Get out there when it’s clean – this is a good one.

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