Sponge bay Surf Forecast and Surf Report

Alright, Rusty here again, but this time in feet and miles for the Imperial crew. Let's break down Sponge Bay.

First few days are a slow start. Water’s a bit cooler than usual, around 55°, so you’ll want the rubber.

Saturday the 29th is the first chance – a small 2ft swell from the southeast with a long 12-second period. The wind is a light offshore from the north, keeping it clean. Wave energy is moderate (132). It’s rideable but nothing special.

Sunday the 30th is even smaller, around 2ft from the southeast, with a cross-offshore wind from the northwest. Still clean, but the energy is low (79). A longboard day.

Monday the 31st of August is the first uptick. Morning brings 2ft SSE swell with a 17-second period and moderate energy (259). Clean cross-offshore wind from the west-northwest. The afternoon pushes to 2ft with energy at 369. Still small, but that long period gives it some life.

Tuesday the 1st of September blows up – a solid 8ft SSW swell, but the period is short at 13 seconds and the combined energy is massive at 2992. Onshore and cross-onshore winds, gusting to 25 mph, with rain. It’s big and messy, not worth it for a paddle.

Wednesday the 2nd of September is the highlight. Swell drops to 7ft from the SSE with a 14-second period. Energy is very strong at 1409. Wind is a clean cross-offshore from the northwest at about 9 mph. The morning is excellent for experienced surfers – clean and powerful. The afternoon holds at 7ft with a 17-second period and even more energy (3429), but the tide could be tricky.

After Wednesday, it fades. Thursday the 3rd has clean wind but only 4ft swell and moderate energy (661). The rest of the week into the weekend is tiny – mostly under 2ft with clean but weak conditions.

There’s a small window on Saturday the 5th afternoon – 5ft SSE swell with a 14-second period and moderate energy (748), but the wind is a side-shore with some cross-chop.

Monday the 7th of September afternoon turns glassy – wind drops to a light 5 mph from the south-southeast, with a tiny 2ft SSE swell. It’s calm and clean but very small.

The second week is pretty flat overall. One pulse on Saturday the 12th of September morning: 5ft SSE swell with a 10-second period and moderate energy (541). Clean cross-offshore wind from the west-northwest. Marginal but maybe a session if the tide is right. Then the wind goes to hell that afternoon with a near-gale onshore.

So, for the Imperial crew, Wednesday the 2nd of September is the one to circle. 7 to 7ft of clean SSE groundswell with a solid period and good wind. Monday the 31st of August is a smaller but cleaner backup.

That’s the story.
