The Lowdown
Alright, Rusty here. Let's be straight up: we're looking at a pretty flat run ahead. The next couple of weeks are a tough time for anyone wanting to get wet around Port Louis.
The swell is just not showing up. For a good stretch, from September 10th right through to the 25th, the wave heights are tiny, barely getting above 2 feet. The energy in the water is weak, almost always below 100, often just in the teens or even down to single digits. It's a desert out there.
The wind is actually great for most of this period – steady offshore from the east, which would make for clean, glassy faces. That's the cruel joke: perfect wind, absolutely no swell to work with. On top of that, Port Louis is an inconsistent spot anyway, so this kind of blank run is more common here. It's just how it goes.
Over the first few days, September 10th to 13th, we're looking at 0.7 ft to 1 ft. Wind is offshore and clean, but the waves are just pathetic. Not worth paddling out for. The water temp is 85° with a 2° anomaly, so it's just a touch warmer than average for this time of year.
The pattern stays the same. The 14th through the 17th, and into the 18th and 19th, we see periods with some risk of thunderstorms and fresh breezes, but the wave height never climbs above 1 ft. The swell direction is mostly N or NNE, which is fine for the spot, but the size is non-existent.
The second week is more of the same. A brief bump on the 21st shows 2 ft from the NE with a period of 8 seconds, but the energy is only 32. That's not enough to get excited about. The 25th of September finally shows a little more life with a 2 ft north swell and a longer period of 11 seconds, pushing the energy to 62, but it's still a tiny wave. It's promising in that it's the best looking day on the cards, but it's not worth a special trip.
There's really nothing here. No standout days, no big swells. If you're desperate, maybe the 25th of September might have a knee-high ripple, but that's a long shot. This is a kite surfer's forecast, not a surfer's. Hang tight, the forecasts can change.

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.

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.
