Castlepoint - The Gap Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming down the line for Castlepoint - The Gap.

Right off the bat, there’s some small, clean surf on offer this Sunday morning. We’re looking at a tiny 1ft SSW swell, but with a 10-second period and a light offshore breeze, it’s rideable. The combined energy is weak (102), so don’t expect much push, but for a beginner-friendly spot, it’s a paddle. The water temp is about average for this time of year.

Sunday afternoon improves a touch—swell bumps up to 2ft from the SSW, with a longer 12-second period, and the wind stays light offshore. The energy picks up to 157, still modest, but it’s clean and glassy. A nice little session for the longboard.

Monday gets a lot more interesting. The morning brings a 8ft SSW swell with a 12-second period, and a strong offshore wind. The energy skyrockets to 1560—that’s a solid pulse. But the wind is strong, 25 mph, making it a real fight to get out. The report flags it as marginal, and at this size, it’s pushing into expert territory. This is the standout for the week. Monday afternoon drops a bit to 7ft, with a fresh offshore breeze, still very clean, but the wind is still strong.

Tuesday sees the swell building even more. Morning is 10ft from the south, with a cross-off shore wind. The energy is 2881—strong, powerful. By Tuesday afternoon, it’s a beast: 15ft SSW, clean with a gentle breeze, and the energy reading is 7618. That is massive energy. The report says the swell is too big for this break, so unless you’re an expert, keep dry. This is the biggest pulse of the forecast.

Wednesday morning drops to 8ft from the south, with a 13-second period, and a moderate offshore. Energy is 2733, and the report calls it excellent for experienced surfers. Wednesday afternoon holds at 8ft but the period stretches to 16 seconds—very long groundswell. At a sheltered spot like The Gap, that long period can mean clean, lined-up waves, but the offshore wind is fresh, 19 mph. Still one of the better days.

Thursday morning sees the swell drop to 5ft, still clean offshore, but the energy is down to 671. Thursday afternoon is 4ft, moderate offshore, and the report says expect good surf. A solid, manageable day.

From Friday 4th September onwards, it gets iffy. The swell drops, the wind turns cross-off, and the reports are poor. There are days with small, clean waves, but nothing to get excited about. A long gap of mediocre surf sets in. Saturday 5th has 3ft, Sunday 6th is poor, and the whole of the following week stays small and weak. There’s a brief flicker on Monday 14th September with a 3ft SSW swell, but the period is a very long 17 seconds, and the energy is 668. The report says expect good surf, so that could be a sneaky clean session with a light breeze.

Overall, the real standout is Tuesday afternoon, 1st September, with that huge 15ft SSW swell—but it’s too big for this spot. The best all-round session for experienced surfers is Wednesday morning, 2nd September. The Gap is a fairly consistent spot, so these waves will come. If you’re a beginner, stick to the Sunday and the smaller Thursday afternoon.

Rusty.
