Alright, Rusty here. Let’s have a look at what’s cookin’ at E-Bay over the next couple of weeks.
Right off the bat, this isn’t the kind of forecast that gets me stoked out of my gourd, but there are a couple of moments that’ll make it worthwhile for the rippers. The water temperature is sitting at a warm 86°, which is about 1° warmer than normal for this time of year – nothing wild, just a touch of extra tropical warmth.
The surf gets going Sunday, July 5th, but honestly, it’s a bit of a mess. We’ve got a 5ft swell from the south with a very long 15-second period, but that cross-on wind from the south at 6 mph has got it looking pretty lumpy and questionable. The combined energy is 1027, so there’s some muscle there, but the quality just isn’t there for a good paddle.
Monday, July 6th, the morning is interesting but borderline. The swell drops to 2ft from the SSW with a 16-second period, energy at 378, but it’s glassy with a light northwest breeze. It looks better than it feels – tiny, but clean. By the afternoon, the wind swings southwest and picks up to 12 mph, and it’s all over. Poor surf.
Tuesday, July 7th morning is where we start to see a glimmer. Clean, offshore wind from the NNW at 9 mph on that 3ft SSW groundswell. The energy is 341, and the conditions are *gentle offshore and clean*. It’s small, but if you’ve got a log or a fish, that’s the pick of the early week, especially with E-Bay being a reef setup – those long period SSW swells love a reef.
Wednesday, July 8th is the real standout in the first week. The swell bumps up to a solid 4ft from the south at 15 seconds, and the wind is offshore from the NNW all day – 6 mph in the morning, 9 mph in the afternoon. Combined energy readings of 773 and 817 mean there’s some proper push in the water, and it’s clean, offshore, and groomed. This is the day to call in sick. E-Bay will have proper, lined-up waves, and with that reef, the long period will be a dream.
The rest of the week and into the second week gets messy and inconsistent. Thursday the 9th through Saturday the 12th sees onshore and cross-onshore winds, swell dropping under 3ft most of the time, and the energy falling to between 162 and 742. Nothing worth stressing about.
There’s a promising blip on Tuesday, July 14th. The afternoon session sees a 5ft south swell with a 16-second period, and it’s glassy – flat calm. The combined energy is a massive 1125, and conditions are described as *excellent for experienced surfers*. That 5ft on a reef with that much energy and no wind is proper, but keep in mind the water will be powerful. This one is a serious contender.
After that, from Wednesday, July 15th to Thursday, July 16th, we get more glassy conditions but with smaller swell – 3ft to 3ft, energy around 400 to 465. Clean, fun, small waves for the loggers. Friday the 17th onwards, the wind turns onshore again, and the surf gets poor through the weekend into July 20th.
So, to wrap it up: if you’re looking for the best waves, circle Wednesday, July 8th for the clean, offshore, 4ft south swell, or Tuesday, July 14th afternoon for that glassy, powerful 5ft bomb. The rest is mostly small and wind-affected. E-Bay is fairly consistent, so this run isn’t a total blank, but it’s not a classic either. Forecasts can change, so keep an eye on it.

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.
