The Lowdown
Alright, let’s get into it. It’s been a pretty bleak stretch for this spot – we’re looking at about two weeks of barely a ripple worth mentioning before anything even shows a pulse. That’s a long dry spell, but to be honest, it’s pretty normal here when the swell angles don’t line up.
The only time I’d bother grabbing my board is right at the very end of the period. Castles (sandbar) is the only break on offer, and it’s not exactly firing. Water temp is 75°, which is well above normal for the season – feels like a warm bath.
Nothing happens until the morning of Sunday, September 27th. The wind finally turns offshore from the NNW, blowing around 12 mph, and things scrub up nice. There’s a small E swell, about 2 ft, with a period of 8 seconds, and the energy sits at 113 (moderate). It’s tiny, but it’s clean. That afternoon is the same story – a touch more energy at 117.
The best session comes on Monday, September 28th. The morning bumps up to 3 ft from the E, period stretches to 10 seconds, and the energy jumps to 279 (moderate to strong). The wind is cross-offshore from the NNW at 12 mph, keeping the surface glassy. This is the standout window. The afternoon’s almost as good, with 4 ft from the ESE and energy at 270. For a spot that’s fairly consistent and can get a crowd, that Monday is your best bet – clean head-high waves with some shape.
It fades pretty quick after that. So if you’re keen, mark that Monday on the calendar. Nothing else worth chasing.

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.
