The Lowdown
Alright, Rusty here. Let’s talk about what’s on the table for E-Bay over the next couple of weeks.
First off, don’t get too keen just yet. The start of this outlook is a bit of a slow burn. We’ve got a few days of pretty ordinary conditions from Monday the 27th right through to the end of July. The swell is tiny – we’re talking ankle to knee high at best, with the wind mostly onshore or cross-onshore, so the surface is going to be bumpy. It’s a real struggle to find anything rideable.
The first real glimmer of hope comes on Wednesday morning the 29th. It’s still only small at 2 ft from the SSW, but the wind goes glassy. That’s rare, and it’ll make the surface like a mirror. The wave energy is still weak though (121), so it’s more of a longboard or log session just to wet the line. Not a standout, but it’s the first bit of clean water we’ve seen.
We’ve got a gap of a few more days with marginal surf and tricky winds before things start to look interesting. The standout window is shaping up for Sunday the 2nd of August. The morning is looking prime: the swell pushes up to 4 ft from the south, and the wind is dead calm – glassy as it gets. The wave energy is strong at 1668, and that long period of 19 seconds means proper groundswell with some real push. It’s still a bit strong for beginners, but for the experienced crew, this is the session to circle on the calendar.
Following that, Tuesday the 4th and Wednesday the 5th also look good. On Tuesday, the swell holds at 4 ft from the south with clean glassy conditions in the morning, swapping to a light cross-offshore in the afternoon. Wednesday afternoon brings a glassy drop to 3 ft but an extra long 20-second period, making for some beautiful, lined-up waves if you’re on a reef or point setup.
Further out, Saturday the 8th of August morning sees the swell bump up to 5 ft with glassy winds. That’s a bigger, more powerful wave – definitely for experienced surfers only, and the energy is solid at 1297. It’s a promising long-range call, but we’ve got a week to wait, so keep an eye on it.
Water temp is sitting about 86°F, which is pretty normal for this time of year, so no need for a wetsuit.
Crowds at E-Bay can pop up sometimes, so if you’re chasing the best clean waves, get in early on those glassy mornings.
Alright, keep it salty out there.
Rusty.

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.
