Table - best surf conditions forecast for Little Austi and Main Beach over the next 16 days.
Alright folks, Rusty here. Let’s get into it for Little Austi and Main Beach. We’ve got a bit of a slow burner on our hands, but there’s a solid chance to score some clean, fun-sized waves if you’re patient.
The first few days of the week are pretty average, with a bit of cross-onshore wind and a lumpy 6ft to 6ft SE swell. The wave energy is moderate (764) but the conditions are marginal, so it’s more of a paddle-around than a standout session. By Friday afternoon, the picture brightens up. That swell drops slightly to 5ft, still from the SE, but the wind goes glassy. That’s a major win. The combined energy is still moderate (509), and the forecast says expect very good surf conditions. This is your best bet for the near term—clean, lined-up waves for the intermediate crew.
Saturday morning holds a cleaner 4ft SE swell with offshore NW wind, making for a clean, fun morning wave. The energy drops off (342) but it’s a nice, mellow session. After that, things get small. Sunday through mid-week sees a rapid drop-off to tiny or flat conditions. The wind turns strong and cross-off, and the energy readings fall into the weak range (100 down to 0). By Thursday the 16th, a bigger 8ft SSE swell tries to push in, but it’s getting absolutely hammered by near gale cross-onshore winds. That’s blown out, messy, and only for the truly committed or those looking for a kite session. The rest of the second week is a write-off with tiny waves and mostly poor conditions.
The standout session is hands-down Friday afternoon, July 10th. Little Austi and Main Beach will see a 5ft SE swell with glassy conditions. The energy is moderate (509) and the forecast is calling for very good surf. This is the one to circle.
This is a beach and reef setup, exposed to the ENE, so it handles the SE swell well. Water temperature is about average for the time of year, so no major surprises there. Keep in mind, crowds can be a factor sometimes, so get out there early.
The long-range stuff is promising but less certain. The swell on the 16th could be a wave, but the wind is a killer. Keep an eye on it, but don’t hold your breath.
Rusty, signing off.
