Alright, let’s get into it. Look, the next 16 days are a mixed bag for Little Austi and Main Beach. The beginning is quiet, with only small, poor-quality surf from Friday the 3rd right through the weekend. You’ll see tiny 1ft to 3ft NE swells with short periods under 8 seconds, and the wind is mostly cross or cross-off, but nothing worth paddling for. It’s a slow start.
Now, Monday the 6th brings a sudden jump in size, but it comes with conditions that are not user-friendly. An 8ft SSE swell rolls in Monday morning with a period of 10 seconds, pushing strong combined energy (1110) onshore. The wind is cross-onshore, making things choppy. This is expert territory at over 8ft – too big for beginners, and the mess means it’s more interesting for kite surfing than paddle surfing.
Tuesday the 7th stays on the big side with 7ft to 8ft SE swells (energy up to 1351 in the morning). The wind is cross to cross-onshore, giving marginal conditions and questionable tides. Still a tough day for most.
The highlight has to be Wednesday the 8th. The morning is something special. You’ve got a 7ft SE groundswell, period of 10 seconds, and the wind goes glassy – completely offshore from the WSW at just 16 km/h. That’s clean, lined-up surf with moderate energy (773). This is the best on offer, and it’s worth a paddle. The afternoon turns cross-onshore and gets a bit choppy, but that morning window is gold.
After that, the swell drops fast. Thursday the 9th sees 3ft to 2ft, mostly poor, and the next week is full of tiny or flat days. Saturday the 11th shows a glimmer of hope with a clean, glassy morning on a 4ft SE groundswell (energy 253), but it’s nothing epic.
From around the 15th of July onwards, it goes completely flat with no recorded swell. That’s a dry spell nearly three days long. For this setup, when the swells are this inconsistent, it’s pretty normal to see long gaps. Keep your eye on the Wednesday morning session – that’s your best wave.
Little Austi and Main Beach can get crowded sometimes, so be ready for company if you chase that Wednesday glass.
