The Lowdown
Hey, Rusty here. Let’s break it down. This stretch around Port Louis is a slow burn, with a whole lot of flat, tiny conditions before we finally get a sliver of hope at the very end.
We’re looking at a long, quiet run. From Monday the 14th all the way through to the morning of Monday the 28th, every single forecast is marked as poor. The swell is negligible, topping out at around 1.0 ft, with wave energy that’s almost non-existent – most readings are between 3 and 31. The wind is often blowing offshore from the east or east-southeast, which would be ideal if there was any swell to groom, but there just isn’t. There’s a weird spike of a very long 15-second period on Wednesday the 16th, but it’s only 0.3 ft – a long period of nothing. The first full week is a total bust.
Finally, on Tuesday morning the 29th of September, things get interesting. Port Louis sees a 2 ft swell from the north-northeast, with a 12-second period and a combined energy of 134 – that’s moderate wave energy. The wind is a moderate offshore from the east, so it should be clean. Out of this whole 16-day run, this is the only moment that’s even worth checking. It’s still small, so it’s perfect for beginners, and since this spot is inconsistent, a day with actual waves is a bit of a novelty. Water temp is about normal for this time of year.
Don’t expect anything else. The rest of that last week is still tiny and poor. That Tuesday morning is your one window of opportunity.
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.
