Updates in hr min s Forecast update imminent
G’day, Rusty here. Let’s talk about The Gap at Castlepoint.
Right now, Tuesday morning’s pushing a 3.0m swell out of the east, combined energy at 2646 (moderate wave energy), but the wind’s onshore and it’s raining lightly. Water temp is 13° – about average. That session’s marginal with crappy tide conditions. Tuesday afternoon gets worse with the wind picking up. Not a great start.
Wednesday and Thursday are a mess – Thursday’s gale-force southerly winds and 5.0m to 5.5m swells (combined energy 5463 to 6950, very strong) mean blown-out, dangerous surf. Don’t bother. Friday stays lumpy with cross-shore winds on 3.0m swell (combined energy 2480-2536, strong). Saturday’s choppy with 1.6m to 2.0m – no good.
Now Sunday the 12th – clean, clear, and a light offshore from the northwest at 5 km/h. Swell is 1.5m from the east-southeast with a 10-second period, combined energy 769 (moderate). The data says “expect good surf conditions.” For a beginner-friendly, sheltered break like The Gap, this is your best bet in the first week. Crowds are often around.
Monday the 13th through Wednesday the 15th are tiny – 0.8m to 1.1m swell, combined energy as low as 123 to 484 (weak). Clean but ordinary.
But hold on – from Thursday the 16th, things heat up. Thursday has a 1.9m east-southeast swell with a very long 14-second period, combined energy 2263 (moderate-strong), and a strong offshore from the west-northwest at 40 km/h. It’s clean but hard to paddle into.
Friday the 17th morning is the standout. Swell of 2.1m from the southeast with a 13-second period (combined energy 1612, moderate-strong), and a gentle offshore breeze from the west at 15 km/h. The data says “expect very good surf conditions.” That long-period groundswell will wrap in nicely, making for powerful, well-shaped waves. Crowds are a given. Not beginner-friendly at that size.
Saturday the 18th drops off – clean but small and poor.
Sunday the 19th afternoon is another gem. A 2.5m south swell with a 9-second period (combined energy 1657, moderate-strong), and light cross-offshore wind from the west-southwest at 10 km/h. “Expect very good surf conditions” – this is clean, punchy, and for experienced surfers.
Monday the 20th is a fun, clean day with 1.3m east-southeast swell and a long 13-second period (combined energy 1000-1184, moderate), near-calm wind, and “expect very good surf conditions.”
Late Tuesday the 21st and Wednesday the 22nd fade, with strong offshore winds making paddling tough.
The best of the lot is Friday the 17th morning, with Sunday the 19th afternoon a close second. The rest is mostly marginal or small, with a few clean windows for the patient.
