Rosa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what Rosa is cooking up for us over the next couple of weeks.

The first few days are a bit of a mixed bag, but the standout window is shaping up nicely from Sunday afternoon through to early next week. We’ve got some serious energy rolling in, with a solid south swell building. The water temp is sitting around 67°, which is about normal for this time of year, so no need to worry about a wetsuit just yet.

Saturday, August 8th is a write-off, to be honest. The swell is there at 7 ft from the south, but the wind is a messy cross-shore from the north at 12 mph, and the wave energy is already high (1576), but it’s choppy and crumbly. Not worth paddling out for.

Sunday, August 9th – things start to change. The morning is still a bit grotty with clouds and a cross-off breeze, but the swell is a clean 6 ft. The real magic happens in the afternoon. The wind drops to a gentle 9 mph cross-off from the SSW, the swell bumps up to 8 ft from the south, period jumps to 11 seconds, and the energy cranks to 2216. This is excellent surf, but it’s pushing towards 8 ft, so it’s for the experienced crew only. If you’re a beginner, sit this one out.

Monday, August 10th – this is the pick of the first week. The morning session is a gem. Swell still 8 ft from the south, but the period extends to 13 seconds – that’s a proper groundswell. The energy is massive at 2870. The wind is a light cross-off from the WSW at 9 mph. The sets will be a bit more spaced out, which makes paddling out easier, and the waves will have real shape. This is the best on offer for the first week. The afternoon sees the wind shift to a cross-shore and the energy drops, so get on it early.

Tuesday, August 11th is a treat for the early bird. The morning is glassy – 3 mph winds from the SSW – and the swell is a clean 6 ft from the south with a 12-second period. Energy is moderate (1049), but the conditions are perfect. The afternoon is also glassy with zero wind, but the swell drops a touch. Both sessions are clean, but the morning has more power.

After that, the wind turns messy from Wednesday through the end of the week. Wednesday, August 12th and Thursday, August 13th are plagued by cross-onshore and cross-shore winds, making the surf choppy and difficult. The swell is still there, but it’s not a fun paddle.

Friday, August 14th offers a bit of relief with a clean cross-off wind from the SW and SSW, but the swell is down to 6–6 ft. It’s rideable, but not the standout.

Saturday, August 15th – a hidden gem. The morning is glassy with a light SSE breeze at 3 mph. The swell is a clean 5 ft from the south with a 12-second period. Energy is low (837), but the conditions are beautiful. If you want a quiet, clean session, this is your window.

Now, the second week gets a bit wild. Sunday, August 16th through Monday, August 17th is a hard pass. The wind is howling onshore and cross-onshore, creating lumpy, choppy conditions. The swell direction shifts to the east, and the period drops to a short 7 seconds. This is not surf for a paddle board; it’s more interesting for kite surfers.

Tuesday, August 18th – the second stand-out window. The morning is still a bit rough with a cross-shore wind, but the afternoon is the real deal. The wind switches to a light cross-off from the SSW at 3 mph, and the swell is 8 ft from the ENE with a 9-second period. The energy jumps to 1702. For experienced surfers, this is excellent. The waves will have a bit of punch, but the wind will keep them clean.

Wednesday, August 19th – the morning is glassy. Clear skies, wind from the SW at 3 mph, and a 7 ft swell from the ENE. The energy is 1115. This is a beautiful, clean session for those who can handle the size. The afternoon gets a bit choppy with a cross-onshore wind.

After that, the swell fades and the wind turns messy. The end of the run from Thursday, August 20th, onward is small and choppy. The swell drops below 5 ft, and the energy is weak. The last few days are a slow fade out.

So, to sum it up: Monday, August 10th morning is the absolute best for a proper, powerful groundswell, and Tuesday, August 18th afternoon is the second standout for a late-season clean session. The rest is a mix of decent windows and days best spent doing something else.

Rusty.
