Cathedral Rock Surf Forecast and Surf Report

G'day, I'm Rusty. Let's get into it.

We've got a solid run of swell coming through at Cathedral Rock. The water's sitting at 57°F, which is about average for this time of year, so nothing to worry about in the wetsuit department.

The first real chance to get wet is Wednesday afternoon the 19th. It's a bit small, 3 ft from the SW, but the wind is light offshore from the north, making for clean conditions. The combined energy is moderate (341). It's a gentle start.

Thursday the 20th sees a slight increase, with a 3 ft WSW swell Thursday afternoon. The wind stays light and cross-offshore, keeping it clean. The energy picks up to 592. Still on the smaller side, but rideable.

Now, Friday the 21st is where things get interesting. The swell jumps to 6 ft on Friday morning, coming from the WSW with a 15-second period – that's proper groundswell energy. The combined energy is a strong 2318. The wind is a light cross-offshore, so the waves will be clean. This is excellent for experienced surfers. By Friday afternoon, it's pumping 10 ft (WSW, 14s) with a massive combined energy of 4780. The wind is still clean. This is a standout session for the experienced crew.

Saturday the 22nd is big, with 10 ft SW swell, but the wind goes cross-shore, making things a bit chop. The combined energy is still very strong around 3801. It's one for the experts, and the crowds might be out, but the conditions are a bit messy.

Sunday the 23rd is a ripper. The swell drops slightly to 8 ft in the morning, but the wind goes light cross-offshore again. The combined energy is 2935. The waves will be clean and powerful. Sunday afternoon is similar with 7 ft and clean conditions. This is another top pick.

Monday the 24th is good, solid 6 ft SW swell with light cross-offshore wind. The energy is strong (1358). It's a solid day of surf.

Tuesday the 25th is a write-off. The wind swings onshore from the SE, making it choppy. The energy is still there, but the quality is gone. Give it a miss.

Wednesday the 26th is still messy with onshore wind, but the swell is 8 ft to 10 ft. It's not great for paddling, but for the kite crew, this setup could be more interesting.

Thursday the 27th sees a return of clean conditions with a light offshore. The swell drops to 3 ft, but it's clean. A good day for a small wave board.

Now, for the second week, we have some promising, but less certain, long-range standouts. Friday the 28th of August is a monster. The swell is 10 ft in the morning, building to 12 ft in the afternoon, with a 16-second period. The combined energy is off the charts at 6264. The wind is light offshore and clean. This is a major event for experienced surfers.

Saturday the 29th keeps the energy high with 12 ft to 13 ft swell, but the afternoon gets a bit of onshore wind. The morning is clean.

Sunday the 30th is still big, with 10 ft swell and light offshore wind in the morning. The energy is strong (2265). The afternoon gets a bit cross-shore.

Monday the 31st is a great session. The swell drops to 6 ft, but the period is a long 16 seconds, and the wind is light offshore. The combined energy is still strong (2194). This is excellent for experienced surfers.

Tuesday the 1st of September and Wednesday the 2nd see the swell fading to 4-4 ft, but the conditions are clean, with light offshore winds and even some glassy conditions. The energy is moderate. These are good small-wave days.

Thursday the 3rd of September starts glassy, but the wind goes onshore in the afternoon. The swell is 4 ft.

So, to sum it up, the standout days are Friday the 21st, Sunday the 23rd, and especially Friday the 28th of August.

Rusty.
