Alright, Rusty here. Let’s break it down.
We got a nice run of surf coming into Gully's, starting Sunday morning, 12 July. Water temp is a balmy 86°, which is a touch warmer than normal for this time of year – feels good on the skin.
Sunday morning kicks off with a clean 3ft SSW swell at 14 seconds. That’s groundswell, carrying some punch. Light cross-off wind from the NW keeps it tidy. Combined swell energy is moderate (451). A solid session to start.
Monday, 13 July, goes glassy all day. The swell drops a bit to 3ft but still from the SSW at 13 seconds. Perfect for the intermediate crowd. The morning is the pick – dead calm.
Tuesday, 14 July, morning glass again, with the swell back to 3ft, 14 seconds, same SSW direction. Clean, consistent. Afternoon turns a bit onshore, so hit it early.
Wednesday, 15 July, morning is glassy with a 3ft SSW swell, 13 seconds. The pattern is holding. Afternoons get stormy – morning sessions are the go.
Thursday and Friday mornings both offer glassy conditions with 3ft and 2ft SSW swells respectively. Friday is smaller but dead calm – fun little waves.
Now the standout of the first week: Monday, 20 July, morning. Clear skies, glassy, and the swell is 3ft from the SSW, but the energy jumps to 601 – moderate to strong – with a 13-second period. This is the best session in the first stretch. Don’t sleep on it.
Tuesday, 21 July, also delivers. Morning rain but light and glassy, a 3ft SW swell at a long 15 seconds. Energy is 510 – strong. Afternoon brings offshore NE wind and clean conditions – another very good window.
From Thursday, 23 July, the swell period drops a little. Thursday morning sees a 3ft SSW swell but only 8 seconds – energy drops to 188, weaker and choppier. Not the same quality. Friday, 24 July, is better: 4ft SSW swell, 9 seconds, light cross-off wind – worth a paddle.
But the true standout of the whole forecast is Monday, 27 July, morning. The swell is only 3ft from the SW, but it’s running at a very long 18 seconds. Combined energy hits 724 – strong. Glassy, clear skies. This is the best wave of the outlook. Long-period groundswell with power – perfect for a point or reef setup.
The afternoons are mostly blown out or onshore, but the mornings are gold for the whole run.
In short: Monday 20 July morning and Monday 27 July morning are your two best calls. The 20th has clean, moderate energy and good shape; the 27th brings long-period groundswell with real juice.
Stay stoked.

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