The Lowdown

Alright crew, Rusty here. Let’s talk about what’s cooking at Avalon-South for the next couple of weeks.

To be straight with you, the first week and a half is mostly flat and ugly. The only real chance to score comes on Monday morning, the 3rd of August, and it’s a long way off, so keep your fingers crossed.

Water temp is about 65°F, right on the average for this time of year. Nothing special.

Let’s walk through it. Thursday, the 23rd of July, we’ve got a tiny 3ft swell from the ENE, period 9 seconds, with a light offshore wind from the W. It’s clean, but the energy is weak (119). It’s rideable, but nothing to write home about. That’s the best of the first week, and it’s pretty weak. From Thursday afternoon all the way through the end of July, it’s a total flat spell. Poor conditions, onshore winds, and nothing worth suiting up for. There’s a little bump on the 31st of July morning with a 4ft SSE swell, but the period is short at 8 seconds and the wind is cross-shore, so it’s messy.

Come August, Saturday and Sunday (1st and 2nd) are still sub-par, but you might find a clean knee-high wave on Sunday morning with a light offshore.

Here’s the one to watch: Monday morning, the 3rd of August. We’ve got a 6ft SSE swell (period 7 seconds) with moderate energy (328). The wind is dead calm, glassy, from the E. That means Avalon-South will be holding clean, decent-sized waves. This is the standout. The wave height is over 5ft, so it’s going to be a bit much for beginners, but for intermediates and up, it’s a solid session. The short period means the waves might be a bit lumpy and close together, but with glassy conditions, it’s the best you’re going to get.

After that Monday morning, the wind turns onshore, and the quality tanks. The rest of the week into the 7th of August is onshore slop, with 3ft to 4ft ESE swell but bad wind. That setup is better for kite-surfing than paddle surfing.

So: the first 10 days are a bust. The one real chance is Monday morning the 3rd of August. It’s a long-range call, so don’t hold your breath, but it’s the only thing on the menu.

Rusty.

Information about the Avalon-South Surf forecast

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