The Lowdown

Alright, let’s have a look at what’s on the cards for the next couple of weeks. The main spot in the mix is the City Beach groyne (beach/groyne), a fairly exposed beginner-friendly break that’s fairly consistent. The water temp is sitting about average for this time of year, so nothing wild there.

The first few days are messy. Wednesday 26th August morning starts with rain showers and a moderate cross-shore breeze, with a 10-foot WSW groundswell packing a huge amount of energy (7017). That’s way too big for beginners and the wind is cross, so it’s a bit of a write-off. The afternoon though, glassy conditions roll in with a light southerly breeze, and the swell drops slightly to 12 feet – still big, but the glassy wind makes it look pretty special for experienced surfers only. The very long period (19 seconds) means longer lulls and better shaped waves, but it’ll be heavy out there.

Thursday 27th morning is a no-go with a fresh cross-shore wind and lumpy conditions. The afternoon cleans up a bit with a cross-off SSE wind and 8-foot swell, but it’s still only marginal.

Friday 28th and Saturday 29th are mostly small and clean but nothing to get excited about – the swell energy drops right off (under 1000), and the waves are small. A bit of a lull.

Sunday 30th August is where things start to fire. The morning has a 7-foot WSW groundswell with a light offshore NE breeze, clean conditions, and the combined energy is pumping (2581). The afternoon gets even better – glassy conditions, 7-foot swell, and light SSW wind. This is the standout of the first week, especially for experienced surfers. The water is clean, the waves are solid, and the wind is perfect.

Monday 31st is a write-off with cross-onshore winds and choppy surf. Tuesday 1st September morning has a clean 8-foot swell but the afternoon turns choppy again.

Then the real golden window opens. Wednesday 2nd September morning is glassy, calm wind, 7-foot swell – excellent for experienced surfers. Thursday 3rd September morning is also glassy with a 7-foot swell. Friday 4th and Saturday 5th mornings have clean cross-off winds and 6-foot swell – very good conditions. Sunday 6th morning is smaller with a gentle offshore wind, clean but weaker.

The second week looks promising but a bit less certain. Monday 7th September morning and afternoon both have a clean 7-foot WSW groundswell with a moderate offshore E wind – excellent for experienced surfers. The combined energy is strong (2374 and 2288). Tuesday 8th September morning is clean but marginal, while the afternoon gets a gentle offshore ENE wind and 8-foot swell – excellent conditions. Wednesday 9th September is smaller and more marginal. Thursday 10th September morning has a 5-foot groundswell with a very long 19-second period and a clean cross-off wind, but it’s a bit further out so keep an eye on it.

The best bet of the whole forecast? I’d be locking in Sunday 30th August afternoon – glassy, 7 feet, and solid. Wednesday 2nd and Thursday 3rd September mornings are also crackers. If you’re an experienced surfer, Monday 7th and Tuesday 8th September afternoons are worth the wait.

The above surf forecast table for City Beach groyne provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at City Beach groyne can be found by selecting the local surf guide option on the grey menu.

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 City Beach groyne 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.
