The Lowdown
G’day, Rusty here. Well, we’ve got a bit of a waiting game on our hands. The first real chance of a surf window doesn’t kick off until Tuesday, the 8th of September, and it’s a pretty modest start. Overall, the next couple of weeks are looking like a mellow stretch, with only one or two sessions that really stand out, so pick your moments.
We start on Tuesday morning, the 8th of September, at Praia da Boraceia. The water’s sitting at 71°F – a touch warmer than normal for this time of year, which is always a nice bonus. Early doors, we’ve got a 4ft S swell rolling in with a period of 10 seconds, and combined wave energy is moderate at 363. The wind is completely glassy – dead calm – so the ocean is like a mirror. This is a beginner-friendly break, and it’s fairly consistent, but with crowds listed as "sometimes," you might have to share the peak. The morning is the call.
Tuesday afternoon holds similar energy with 4ft S swell and glassy conditions, but don’t expect any fireworks.
Wednesday the 9th brings a drop in swell to 3ft from the ESE, but the period shortens to 8 seconds. Morning glass keeps it clean for a grovel session, though light rain is on the cards. Afternoon turns to heavy rain, but it’s dead calm again with 3ft ESE swell.
Thursday the 10th sees the swell drop further to 3ft, but the period stretches to 12 seconds – a longer period groundswell that will have more push for its size. Morning is clean with a cross-off breeze, but it’s small. The afternoon goes glassy again with a 3ft, 13-second S swell and moderate energy (347). This is the standout for the first week. For a beginner-friendly spot, these conditions are about as good as it gets: clean, glassy, and that longer period will give you some proper shape on the face.
Friday the 11th continues the theme – 3ft S swell, 13-second period in the morning with glassy conditions and light rain. The afternoon turns clear with a cross-on breeze, which is a downgrade. The swell holds, but the wind makes it less ideal.
Now, we hit a rough patch. Saturday the 12th is ugly – a 1ft, 11-second swell in the morning with 9 mph cross-on wind, making it choppy. The afternoon improves in height (4ft) but the period drops to a shocking 6 seconds, with cross-on wind. Forget it.
Sunday the 13th is bigger but messy – 5ft S swell in the morning, but period drops to 10 seconds and it’s cross-on at 6 mph. Combined energy is strong at 515, but it’s not clean. The afternoon is similar at 5ft with 9 mph cross-on – poor conditions.
Monday the 14th sees the biggest swell so far – 6ft ESE with a short 7-second period, cross-shore wind, and strong energy at 541. Too junky and messy for a good paddle. The afternoon hits 6ft, but again, short period and cross-on breeze. This is more of a kite-surfing setup than a surfer’s dream.
Tuesday the 15th offers a bit of relief. Morning brings a 5ft SE swell, period of 9 seconds, and a clean cross-off breeze. Combined energy is moderate-high at 370. Afternoon holds 4ft with the same clean cross-off winds. This is a decent, clean option if you’re chasing something rideable.
Wednesday the 16th is back to glass – 3ft S swell, 12-second period, moderate energy at 378. Morning glass again. Clean and small.
Thursday the 17th is marginal – 5ft S swell in the morning, but onshore winds at 6 mph and a 9-second period. Not great.
Friday the 18th finishes the week strong – morning is glassy with 3ft S swell and 10-second period. Afternoon goes glassy again with 5ft ESE, but a short 6-second period – still, glassy conditions make it workable.
Saturday the 19th and Sunday the 20th both offer glassy mornings with small swell (4ft to 5ft) from the ESE or E, but periods stay short (7 seconds). Clean, but gutless.
The second week (from Monday the 21st onward) is quiet – Tuesday the 22nd has a tiny 2ft S swell, and Wednesday the 23rd offers a 3ft S swell with a clean offshore breeze at 6 mph, but combined energy is weak (94-164). Nothing to get excited about.
To wrap it up: your best bet is Thursday the 10th – small but perfect glass, longer period S swell, and clean conditions. The second pick is Tuesday the 15th – a bit bigger with clean cross-off winds. After that, it’s small and clean at times, but don’t expect any barrels.
Stay patient, and keep an eye on the sky.
Rusty.

Information about the Praia da Boraceia Surf forecast
The above surf forecast table for Praia da Boraceia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia da Boraceia can be found by selecting the local surf guide option on the grey menu.
