The Lowdown
G’day, I’m Rusty, and here’s the outlook for Castle Cove over the next couple of weeks.
Right now, the surf is a bit of a slow starter. The first decent window we get is Monday the 14th, but honestly, it’s nothing to write home about. Monday morning has a 5ft SW swell, period of 13 seconds, and a moderate cross-shore breeze from the NW. It’s not terrible, but it’s not great either. The water’s sitting at 58°, which is a touch warmer than normal for this time of year. That’s a nice little bonus if you’re paddling out.
Tuesday the 15th is a write-off. We’ve got rain showers and strong onshore winds cranking from the SW, pushing a big 15ft to 16ft swell straight onshore. That’s messy, blown-out, and honestly, not worth the effort. The energy is massive (7497 to 9778), but with the wind howling, it’s a total mess.
Wednesday the 16th and Thursday the 17th are a bit better, but still rough. We’ve got 15ft to 16ft SW swells with a long period (14-15 seconds), but the wind stays cross-onshore. The energy is still very high (9354 to 9805), but the chop is going to make it tough. Friday the 18th is the first real standout. Friday morning has a 12ft SW swell, period 17 seconds, and a moderate cross-shore breeze from the NW. The energy is massive (8790), and the swell is long-period groundswell. This is a big, powerful swell, so it’s one for experienced surfers only. The wave quality will be good, but with that size and power, you’ll need to be on your game.
Saturday the 19th drops off a bit, with a 8ft to 10ft WSW swell, but the wind stays cross-shore. It’s not the best, but still surfable.
Sunday the 20th morning has a 15ft WSW swell with a cross-offshore breeze from the NNW, and the energy is still high (5449). The morning looks clean, but the afternoon gets smashed by a strong cross-onshore wind that’ll ruin it.
Now, the real standout is Monday the 21st. Monday morning has a 18ft SW swell, period 15 seconds, and a light cross-onshore breeze from the SSE. The energy is massive (13383), and the wind is light enough to keep the surface clean. Monday afternoon is even better: a 20ft SW swell, period 16 seconds, and a light cross-offshore breeze from the ESE. The wind is clean, the swell is huge, and the energy is off the charts (18999). This is a serious swell, and the wind is favorable. That said, at this size, it’s strictly for experts. The break is exposed to the swell, so it’ll be big and powerful.
Tuesday the 22nd is another good day. Tuesday morning has a 15ft SW swell, period 16 seconds, and a light cross-shore breeze from the NW. The energy is still high (9594), and the wind is light. Tuesday afternoon is glassy, with a 12ft SW swell and a period of 15 seconds. The wind is calm, and the surface is perfect. This is a great window for experienced surfers.
After that, the surf drops off a bit. Wednesday the 23rd and Thursday the 24th have 8ft to 8ft SW swells, but the wind is mostly cross-onshore. It’s surfable but not great.
Friday the 25th is better, with 7ft to 8ft SW swells and a cross-offshore breeze from the ESE. The energy is moderate (1474 to 1864), and the wind keeps it clean.
Saturday the 26th is a nice day. Saturday morning has a 6ft SW swell, period 16 seconds, and a light offshore breeze from the NNE. The wind is clean, and the swell is a nice size for intermediate surfers. Saturday afternoon has a 7ft SW swell with a cross-offshore breeze, still clean.
Sunday the 27th is a write-off again, with a massive 16ft SW swell, period 19 seconds, and a strong cross-onshore wind. The energy is massive (16320), but the wind will ruin it.
Monday the 28th and Tuesday the 29th are better. Monday has a 10ft to 12ft SW swell with light onshore winds, and Tuesday morning has a 6ft SW swell with a light offshore breeze from the NE. That’s a clean, smaller day for the more experienced crew.
So, the best on offer is Monday the 21st and Tuesday the 22nd. Monday has a huge 18ft to 20ft SW swell with clean wind, and Tuesday is glassy with a 12ft SW swell. Both are for experts only, but the quality is there.
Signing off, Rusty.

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