Rosa Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for Rosa over the next couple of weeks.

We’ve got a bit of a slow start, but the real action kicks off later. The first few days are a mixed bag, but there’s some serious energy building towards the end of the first week and into the second. The water temp here is doing its usual thing for this time of year, nothing freaky, just standard autumn conditions.

Let’s get into it.

Monday 7th September starts off with a bang. A solid 6 ft swell from the S, with a 10-second period, and a light SW cross-off wind. That’s a clean combo, and the energy is moderate (551). This is the standout for the start of the period. The morning is definitely the time to be out there. The afternoon, however, the wind swings onshore and the tide turns it into a bit of a gamble.

Tuesday 8th is a write-off. The swell drops, the wind is messy, and by the afternoon it’s a choppy, cross-on mess. Give it a miss.

Wednesday 9th morning is a little gem. Glassy conditions with a 5 ft swell from the ENE. The period is a short 8 seconds, but that glassy surface makes it a fun, clean wave. The energy is moderate (588). The afternoon gets a bit bumpy.

Thursday 10th sees a shift. The morning is small and messy, but the afternoon brings a 4 ft swell from the S with a very long 15-second period. The wind is a light cross-off, so it’s clean. The energy is moderate (676). This is a true groundswell, so expect long waits between sets, but the waves will be well-shaped. Best on the points or reefs if you can find them.

Friday 11th is a complete washout. Rain and onshore wind kill the vibe. Small, weak, messy.

Saturday 12th morning is a flat, glassy calm with a tiny 4 ft swell. Barely worth a paddle. The afternoon, however, gets a big jump to 8 ft from the SSW, but with a short 7-second period and a 19 mph cross-off wind. That’s a lot of wind for a short-period swell. It’s powerful though (751). For experts only, and even then, it’s a wild ride.

Sunday 13th is a beast. Swell jumps to 8 ft from the SSE, with a moderate 11-second period and a lot of energy (1591). But the wind is cross-shore and the rain is on. It’s powerful, but it’s not clean. Only for the experienced.

Monday 14th morning is the absolute standout of the whole forecast. Glassy, calm, with a solid 7 ft SSE swell at 10 seconds. The energy is strong (1020), and the conditions are pristine. This is the one. Get out there early. It’s a big swell, so it’s for the more experienced surfers, but the glassy surface will make it a dream.

Tuesday 15th is a step down. The morning is clean with a 5 ft SE swell, but the afternoon turns choppy.

Wednesday 16th is small and clean in the morning, but nothing to write home about.

Thursday 17th is a solid return to form. The morning has a 6 ft S swell with a light cross-off wind and clean conditions. The energy is moderate (849). The afternoon is smaller but still clean. A good, solid day.

Friday 18th is a big one. Swell jumps to 8 ft from the S with a long 12-second period and a massive 1645 energy. But the wind is onshore and the conditions are unknown. It’s a powerful, dangerous swell. Only for the real experts.

Saturday 19th is messy with rain and cross-shore winds. A drop in size and quality.

Sunday 20th is a late surprise. Two big pulses of 8 ft from the ENE, with a short 8-second period but clean cross-off winds. The energy is high (910 and 1584). It’s a lot of wind, but it’s offshore, so the waves will be clean. For experts only.

Monday 21st morning is glassy with a 5 ft ENE swell. Clean and fun. The afternoon gets a bit messy.

Tuesday 22nd finishes the run with a solid 7 ft NE swell, but the wind is cross-shore. It’s rideable, but not the best.

So, if you’re picking your moment, Monday 14th morning is your absolute best bet. Glassy, clean, and a solid 7 ft swell. That’s the one. The Monday 7th morning and Thursday 10th afternoon are also strong runners. The second week has some big, powerful swells, but they come with more wind and rain, so be ready for a challenge.

Rusty out.
