Castles Surf Forecast and Surf Report

Alright, Rusty here. Let's talk about what’s on the menu for Castles over the next couple of weeks.

The immediate forecast is a bit of a slow burn, but there are some juicy windows shaping up, especially for those who don't mind a bit of size. The first few days offer some clean, rideable waves, but the real standouts are tucked away in the first half of September.

Right off the bat, on Sunday the 30th of August, we’ve got a fun little pulse. Morning glass is clean with a light offshore breeze from the ENE, and the swell is a gentle 2 feet from the SW with a very long period of 19 seconds. The energy is moderate (452), and it’ll be a bit inconsistent with those long gaps between sets, but the paddle out will be a breeze. By the afternoon, the swell jumps to 4 feet from the same SW direction, still with that dreamy 19-second period. The wind goes cross-offshore and the energy jumps way up (1016), making for some really clean, punchy waves. This is the kind of session where you’ll want a board with some paddle power to catch those long-period gems.

Monday the 31st keeps the same SW groundswell going, now pushing 5 feet with the period dropping just a hair to 18-19 seconds. The wind stays cross-offshore from the NNE, keeping the face clean. The energy is very strong (1642), so the ocean has some grunt. The forecast notes some possible tide issues, but if you get the bank right, the waves will be lined up.

Then things get messy. From Tuesday the 1st through Wednesday the 2nd of September, the wind goes onshore or cross-shore strong, turning the ocean into a jumbled mess. A mid-week lull sets in with poor surf conditions. We see a jump in size on Wednesday afternoon up to 7 feet, but with a full onshore wind, it’s just a lumpy beast. Kite surfers might love that wind and chop, but for a paddle surfer, it’s a write-off.

Thursday and Friday (the 3rd and 4th) get a bit better. The wind backs off, becoming a light cross-shore on Thursday morning with 5 feet of SW swell, but the period has dropped to 14 seconds, so it’s lost some of that groundswell magic. It’s marginal but rideable. Friday morning looks cleaner with a cross-offshore breeze and 6 feet of SW swell, but the energy is still solid (1418).

The 1st of September weekend turns brutal again. Saturday the 5th sees the swell explode, hitting 8 feet in the morning and then a massive 11 feet in the afternoon from the SW. This is expert territory only, and with a strong cross-onshore wind, it’s going to be a washing machine. The energy readings (2531 and 10483) tell you exactly how much power is in the water—it’s dangerous.

The first real standout of the long-range forecast hits on Wednesday the 9th of September. The morning is glassy again with an offshore breeze from the east, and the swell is a solid 7 feet from the SW with a 14-second period. The energy is very strong (1806), but the conditions are clean. This is a big, powerful session for experienced surfers. The banks at Castles will need to handle that size, but when it’s clean and offshore, that reef can line up beautifully.

The second standout, and arguably the best bet for most surfers, comes on Thursday the 10th of September. Morning winds are light offshore from the east, the swell drops to a much more manageable 4 feet from the SW, but the energy is still moderate (504). This is a classic ‘clean up day’—the ocean is settling, the wind is perfect, and the waves should be clean and user-friendly. A bit of a long period (12 seconds) keeps the quality up.

After that, we have a bit of mix. Friday the 11th looks decent with a cross-offshore breeze and 5 to 6 feet of SW swell (1482 energy), and then Monday the 14th closes out the 16-day window with another clean, offshore morning and 5 to 6 feet of SW swell. That Monday session (14th of September) looks like a solid, consistent option with gentle offshore wind, making for a really pleasant paddle.

To sum it up: If you want the best combination of size and cleanliness, circle Wednesday the 9th of September for the big, clean power. For the best all-round session with manageable waves and perfect wind, Thursday the 10th of September morning is your clear winner. The rest of the window has its moments, but those two dates are the ones to plan your week around.

Rusty.
