The Lowdown
Alright, folks, let’s talk about what’s on offer for Port Louis over the next couple of weeks. I’m gonna level with you right off the bat: this is a tough stretch. We’re staring down a long, quiet period with next to nothing worth paddling out for.
Looking at the whole run, the first real sniff of any decent energy doesn't show up until the 8th of September, and even then, it’s marginal at best. Before that, from Tuesday afternoon (1st September) right through to the 7th, we’ve got a dead zone. Tiny little dribbles of swell, mostly 0.3ft to 0.7ft, with the odd puff up to 2ft on the 1st, but that early one was so weak (combined energy just 42) and the period short at 8 seconds that it was a total non-event. The water temperature is sitting at 84° which is about normal for this time of year.
Honestly, for the first week, you’re better off finding something else to do. There’s a solid gap of about six days there with no real recommendations. It’s a flat spell, plain and simple.
Now, onto the better part – or what passes for better here. The 8th of September, Tuesday, starts to show a little life. By the afternoon, we’ve got a 2ft swell from the NNE with a period stretching out to 12 seconds. That’s a longer period groundswell, which means more shape, but with the combined energy at 100 (moderate), it’s still small. The wind is offshore from the ESE at 16 mph, so it’ll be clean. For the morning of the 9th, Wednesday, similar story: 2ft, NNE, 12 second period, energy at 99, and a fresh offshore breeze from the east at 19 mph. That’s your best window – clean, but tiny.
The standout, if you can call it that, is Port Louis itself. On the 8th and 9th of September, you’ve got some of the only real swell in the whole forecast. That NNE direction is right in its wheelhouse (optimum is NNE). The wind stays offshore, which is a major positive. Don’t expect much size – 2ft is all you’re getting – but it will be clean. Crowds are possible here, it can get busy, but with waves this small, it might not be an issue.
Into the second week, from the 10th onwards, it’s back to the same old story: dribbles of 0.7ft to 1ft, mostly with offshore winds, but the energy is weak (low double or single digits). The 15th and 16th of September see a bit of a pulse from the NNE again, with periods around 14 to 16 seconds – very long period – but the size is only 0.7ft to 1.0ft. That long period will make it feel a bit more powerful at a point break or reef, but there’s just not enough height to get excited about. The wind stays offshore, which is nice, but there’s no power behind it.
So to wrap it up: the first week is a complete washout. The best chance for a paddle is the 8th and 9th of September, with clean, 2ft groundswell at Port Louis. After that, it fizzles out again. It’s a tough outlook, but that’s how it goes sometimes. Forecasts can change, so don’t give up hope entirely.

Information about the Port Louis Surf forecast
The above surf forecast table for Port Louis provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Port Louis can be found by selecting the local surf guide option on the grey menu. Our Port Louis surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Port Louis) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Port Louis may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Port Louis is 19 km (12 miles) from the city of Sainte-Rose. If you plan a holiday in Guadeloupe - Grande Terre, look for hotels and other accommodation in Sainte-Rose. Sainte-Rose has rooms for a wide range of budgets as well as car hire and transport links.
