Oyster Bay Surf Forecast and Surf Report

G’day, I’m Rusty, and I’ve been chewing over the numbers for Oyster Bay (sandbar) all morning.

Right now the water’s sitting at about 63°F, which is a bit colder than usual for this time of year – you’ll feel that extra chill paddling out.

The first bit of half-decent surf shows up Sunday morning (August 2nd) with a 8ft east swell at 8 seconds. It’s clean but the energy’s strong (1464) and that short period means it’ll be a bit of a pushy, dumpy wave – not really worth going crazy for. Sunday afternoon sees the swell drop slightly to 7ft but the period stretches to 12 seconds, so there’s more shape, but cross-off wind makes it a bit tricky.

Monday morning August 3rd is where it starts to look good. Clean 6ft easterly groundswell at 11 seconds with light offshore NE wind – that’s glassy conditions and the wave energy is pumping (1694). This is the standout for the first week: solid chest-to-head-high waves, clean faces, and that offshore grooming will make for some fun lines. Crowds can be around here sometimes, so get in early.

Tuesday August 4th keeps the run going with 5ft SW swell on the morning and 4ft in the afternoon, both with that lovely NNE offshore wind, glassy and gentle. The period is 12 seconds so proper groundswell, perfect for the sandbar. The energy’s moderate (1023/766) but the quality is there.

Then things go messy from Wednesday August 5th onwards – Wednesday morning is small cross-onshore chop, and by afternoon it’s a 19 mph cross-on disaster with only 4ft. Thursday August 6th pumps up to 12ft SW at 13 seconds but the wave energy is massive (4102) – that’s too big for this break and the wind is cross. Friday August 7th is similar: 10ft SW swells but strong wind. Saturday August 8th is a write-off – 25ft SW and 34 mph near gale cross-on, combined energy of 19553 – that’s dangerous, not surfable.

Sunday August 9th is huge with 23ft SSW at 16 seconds and energy at 24103, but again, it’s way too big for Oyster Bay. The entire period from August 5th through August 11th is largely blown out or too big – there’s a real gap of no punchy, clean surf.

The next real glimmer comes Wednesday morning August 12th: glassy conditions, 6ft SSW at 15 seconds, light offshore NNW – that’s going to be beautiful, long-period groundswell with clean lines, just maybe a bit fat for the sandbar. Perfect for an intermediate who knows the spot. Energy is moderate (1399).

Thursday August 13th is clean again in the morning with 5ft SW at 12 seconds, light ENE cross-off wind. Another good one. Friday and Saturday are average with cross-shore chop.

The final highlight is Monday August 17th – 7ft SW at 14 seconds, glassy with light NE wind, and energy at 1556. This is the best of the long-range call: solid chest-plus, clean, and that groundswell will draw nice lines across the sand. The afternoon holds 7ft SW at 13 seconds, also clean. This one’s a promise.

So for the whole 16-day run: Monday August 3rd morning is the clear champion – offshore, 6ft, clean, solid energy. Monday August 17th morning is your long-range standout if you’re patient, but that’s a week and a half away so keep an eye on it.

Rusty.
