The Lowdown
Alright, Rusty here, let’s talk about what East London’s got brewin’. This run’s a bit of a mixed bag, with that early window looking average, but there’s some real firepower building towards the end of the period if you’ve got patience.
The first few days are pretty flat and messy. Thursday the 30th of July through to the following Wednesday sees Bonza Bay dealing with a constant cross-shore wind and small, short period ESE swell around 5ft to 6ft. The wave energy is weak to moderate (989 down to 327), and the wind just never gets right. It’s choppy, lumpy, and not worth getting wet for. You’re looking at a solid week of average-to-poor conditions.
Things start to change on Thursday the 6th of August. The wind finally swings offshore (WSW) and that old SSW groundswell shows up with a longer 14-second period. The swell is small at 4ft, but the cleanup crew is in, making for smooth, clean waves at Bonza Bay. The energy is moderate (835) and while it’s not a stand-out, it’s the first real chance of a surfable wave in a week.
The stand-out window is that Sunday the 9th of August through Tuesday the 11th. A big SSW pulse hits, pushing 10ft with strong energy (around 2874 to 4880). Now, a word of caution: that 10ft is well over the 8ft mark, so this is expert territory. The period is a punchy 12 to 16 seconds, which is proper long-period groundswell. On Sunday the 9th, the wind is cross-off and clean in the morning.
The absolute best bet on offer, however, is Wednesday the 12th of August. The swell drops back to a manageable 5ft from the SSE, but the magic is in the wind. The morning is glassy – dead calm – with those long 13-second intervals. The water temp is average for this time of year. The break might get busy, so get there early, because glassy conditions and a decent little swell at Bonza Bay is a rare treat. Expect very good conditions (energy at 840).
Thursday the 13th also kicks off glassy, but with a bigger 7ft E swell. It’s a solid option, but that Wednesday morning is the true standout.

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 Bonza 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.
