The Lowdown
Alright folks, Rusty here. Let’s take a look at what Cap Sim has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a long, barren run that starts now and goes all the way through to the morning of Monday, 18th August. That’s over a week of nothing but poor surf conditions. The wind is a constant cross-off, which keeps things clean, but the swell is tiny or confused, and the energy levels are just sad. Most of the time the combined energy here is struggling – we’re seeing numbers like 25 and 65, barely a whisper. It’s a real kick in the teeth for anyone keen on a paddle.
Now, the water temp is sitting at 62°F with a massive anomaly of -9°F, which is much colder than normal for this time of year. That’s a real shock to the system, so don’t even think about a shorty.
The first real glimmer of hope comes on Tuesday, 18th August. The morning sees a little bump in swell, 4ft from the NNW, with a period of 8 seconds. The wind drops to a light breeze, so it’s glassy clean. The combined energy hits 161, which is still weak, but it’s the best we’ve seen. The waves are ordinary, but surfable. The afternoon keeps it marginal, with 4ft from the NNW at 9 seconds and gentle breeze. It’s not going to be pumping, but if you’re desperate, you might get a few.
Wednesday, 19th August, is similar. Morning and afternoon both offer 3ft from the NNW at 8 seconds, with gentle winds and a combined energy around 157-160. Again, it’s surfable but nothing to write home about. The break is a reef, so that longer period swell (8-9 seconds) will be better shaped here than at a beach break, but it’s still small.
After that, it’s back into the doldrums. From Thursday, 20th August, right through to the end of the forecast on Monday, 24th August, we’re back to mostly poor surf conditions. The swell tries to pick up a little, with some 5ft to 5ft from the north late in the run, but the wind is a fresh breeze and the energy is still moderate. The standout is the morning of Friday, 21st August, where the wind goes offshore, but it’s a strong breeze at 25 mph, which makes it tough to paddle into. The same goes for Saturday, 22nd August. The waves are clean, but it’s a battle.
Honestly, if you’re looking for the best on offer, it’s the week of the 18th and 19th. It’s not classic Cap Sim, but it’s the only window where the wind is light and the swell is just enough to get a few. Don’t expect crowds – the break is a reef, so it’s not a beginner spot, and it’s inconsistent. This is one for the dedicated locals who just want to get wet.
Stay patient, lads. The ocean will turn eventually.
Rusty.

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.
