The Lowdown
Alright, Rusty here, let's take a look at what's on the menu for the next couple of weeks.
Honestly, it's a tough start. We've got a long dry spell ahead. For the first full week, from Sunday the 2nd all the way through to Saturday the 15th, the surf is looking pretty bleak. There's nothing really worth paddling out for. It's a real flat spell, so don't bother waxing up yet. The wait is on.
The only real action on the horizon, and the standout of the whole forecast, is that pulse of energy rolling in on Sunday the 16th. Avalon-South is where it's at. We're looking at a clean 7ft swell from the SSE with a solid 11-second period. The wind is light offshore from the W, which is exactly what you want. It's going to be a proper session. The combined energy is solid at (1142), so there's plenty of power. But keep in mind, at that size, it's pushing into expert territory – over 8ft on the face in some sets. Not one for the groms.
The morning of Monday the 17th still has some leftovers, with a 4ft SSE swell and glassy conditions. That's a more manageable size for a wider range of surfers, and the energy is still moderate (293). The afternoon, however, gets blown out by a NE cross-onshore, so make the most of the morning.
The water temp at Avalon-South is sitting at 64°, which is about average for this time of year, so a spring suit should be fine.
So, to sum it up: a whole lot of nothing for a week and a half, then a very promising, but expert-level, day on Sunday the 16th. Keep your eyes on the charts for that one.
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.
