The Lowdown
Alright, this is Rusty, and I’ve got a straight-up bummer of a look ahead for Port Louis. We’re looking at a long, dry spell where the ocean just isn’t delivering anything worth paddling out for. The first real sniff of any surf energy doesn’t show up until Monday the 7th, and even then, it’s barely a whisper.
For the first few days, it’s flat. Like, *flat* flat. A tiny 0.3ft ripple from the north on Friday the 4th is just not going to cut it. The wind is offshore, which is a tease, but there’s nothing for it to work with. Don’t even bother waxing the board.
That little bump of energy finally arrives on Monday morning the 7th. We’ll see a 1ft north-easterly groundswell, but the period is a long 12 seconds. The combined energy is still weak at 35. Don’t get too excited though. The swell ticks up a bit for Monday afternoon, hitting 1ft from the NNE with an 11-second period. The combined energy finally breaks into the moderate range at 102. The wind is clean offshore from the ESE. You might get a tiny, clean wave at Port Louis, but it’s going to be inconsistent and small. It’s a beginner wave on a good day, and this is barely a good day.
The best we’ve got in the whole 16-day window is Tuesday the 8th. The morning shows a 2ft swell from the NNE with a solid 11-second period, and the combined energy is 121. The wind is a fresh offshore from the east at 19 mph. The afternoon is similar, with a 2ft NE swell, 12-second period, and a combined energy of 148. The wind stays offshore. This is the peak. It’s still small, and the break is inconsistent, so you’ll be sitting out there waiting. But for a brief window, it’ll be the cleanest little wave on offer.
From Wednesday the 9th onwards, it’s a slow bleed back down to nothing. The waves shrink back to 2ft and then just keep dropping. The wind stays offshore or cross-offshore, but it doesn’t matter because the swell is gone. The energy values drop back into the double digits, and by the 18th and 19th, we’re back to 0.3ft ripples.
The water temp is a warm 85°F, which is about normal for this time of year, so at least you won’t freeze while you’re floating around doing nothing.
Look, it’s a grim outlook. A blank run like this is pretty normal for this area when the swell windows don’t line up. The only real stand-out, and I use that term loosely, is the afternoon of Tuesday the 8th. It’s the biggest and cleanest we’ll get, but it’s still only for the most patient surfers who are happy to catch a few knee-high peelers. Don’t set your alarm.
Rusty.

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.
