The Lowdown
Alright, let’s get this straight. I’m lookin’ at the whole 16-day window and honestly, it’s a bit of a tough one. There’s no surf on offer right now at the start, and the first few days are a write-off. We’re looking at a gap of several days with no real recommendations, so don’t be in a rush.
Then, we’ve got a stretch where there’s swell, but it’s all pretty average. The wind is a constant problem – it’s either a strong offshore that makes it hard to paddle into, or a cross-off breeze that keeps things messy. The only spot on the radar is Cap Sim, a reef break that’s fairly consistent. The water temp is a brutal 64°F, which is 7°F colder than it should be for this time of year – that’s seriously unusual, so bring a thick wetsuit if you’re brave enough to get in.
The best of a mixed bag looks like Thursday, August 15th and Friday, August 16th. We’ve got a solid 7ft north swell rollin’ in, with a combined energy of 396 (moderate) on the Saturday morning. The wind is a fresh breeze from the north, cross-off, so it’s clean but not glassy. The period is short at 7 seconds, so it’s a bit of a windswell – not the best shape, but it’s the only time the numbers line up. The swell direction is north, but the optimum here is northwest, so it’s not a perfect match.
Keep in mind, this is an advanced reef break, so when the swell hits 7ft, it’s only for experienced surfers. It’s not too big for experts, but beginners should stay well clear. The crowds are possible here – it says “sometimes,” so don’t expect to have it to yourself.
After that, things drop off fast. By Monday, August 18th, the swell is tiny, and the energy is weak (52). Then it’s a long, flat run to the end of the window, with nothing but small, weak swells that aren’t worth paddling for. The last few days show barely a ripple, with energy down to single digits. So, if you’re desperate, that Thursday and Friday in the second week are your only real shot, but keep your expectations low.

Information about the Cap Sim Surf forecast
The above surf forecast table for Cap Sim provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cap Sim can be found by selecting the local surf guide option on the grey menu. Our Cap Sim 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 (Cap Sim) 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 Cap Sim 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.
Cap Sim is 16 km (10 miles) from the city of Essaouira. If you plan a holiday in Central Morocco, look for hotels and other accommodation in Essaouira. Essaouira has rooms for a wide range of budgets as well as car hire and transport links.
