Table - best surf conditions forecast for Castles over the next 16 days.
Alright, surfers, Rusty here. Let's look at what we've got for Castles.
Honestly, it's a pretty bleak run ahead. We're looking at a long stretch of small, weak, or just plain messy conditions. The water is running about 77°F which is *much warmer* than usual for this time of year—pretty unusual, so that's a nice little bonus if you’re just floating around.
The first week is a write-off for any decent surf. From July 11th right through to the 19th, the wave energy is tiny, mostly under 50 (combined swell energy), with short, weak periods. Winds are all over the shop—cross, cross-on, and onshore—keeping things choppy and blown out. You'd be better off doing something else than paddling out at Castles.
Now, there is a glimmer of hope, but you’ve got to wait for it. On Monday, July 20th , the swell finally shows a pulse. We’re looking about 5ft of S swell early that morning. The combined energy jumps right up to a moderate 190, so there’s actually some push behind it. The wind is light from the NNW, making it clean offshore. That's the standout of the whole period. It won't be huge or perfect, but after all the doldrums, it’ll feel like a gift.
The swell builds after that, with waves hitting 5ft to over 7ft during the week of July 22nd to 25th. That’ll be too much for beginners and gets into expert-only territory. The problem is, the wind is almost always cross-onshore or choppy, so the quality is poor, despite the size. The energy is high (over 300 at times), but it looks like a messy, blown-out mess. On Saturday, July 25th , there's a morning window with about 5ft S swell and light onshore winds, which is rated as marginal, so maybe a dawn patrol gamble if you’re desperate.
Forget the last few days of July, it just drops off again.
Best Bet: Wait it out for Monday, July 20th morning at Castles. The 5ft S swell with that clean offshore wind is the only real moment the pieces line up.
Rusty.

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