The Lowdown

Alright, let’s get into it. The next couple of weeks are looking pretty ordinary for Cap Sim. We’ve got a stretch of poor conditions and small, jumbled swell, so you’ll need to pick your moments. The water is way colder than it should be for this time of year – we’re talking about a 7° difference from average, which is very unusual, so grab the thickest suit you’ve got.

The next week is pretty much a write-off. From Tuesday through to the following Monday, it’s mostly onshore or strong cross-offshore winds with weak, short-period swell. There’s a small bump of 5ft on Wednesday morning, but the period is only 6 seconds – that’s just wind chop, not worth getting wet for. The energy is weak to moderate at best, hitting around 309 in the morning. The winds are fresh, so it’s going to be messy.

Thursday drops right off, with the swell fading to under 3ft and the energy tanking to 54. That’s a real struggle day. The winds stay strong and offshore, but with that little swell, it’s just a tease.

Friday morning brings a bit more life, with 6ft of short-period north swell and energy back up to 477. It’s a fresh offshore wind, so it’ll be clean, but the 8-second period and the north direction are not ideal for this spot. It’s a marginal call, and the tide could be a factor. The afternoon jumps to 7ft, but the wind swings north at 25 mph, making it a blown-out mess. This one is for the experienced guys only if they’re desperate, but it’s not going to be pretty.

The weekend is a bit of a mixed bag. Saturday morning has 6ft of NNW swell, but it’s cross-offshore winds and the period is still short at 8 seconds. Energy is moderate, around 461. It’s surfable, but the conditions are questionable. It stays around 5ft into the afternoon with the same issues. Sunday morning is poor with the wind turning cross-on from the SSW. The afternoon, however, finally gives us something. The wind drops light and goes cross-off from the east, and there’s 3ft of clean, 8-second swell. Energy is still low at 248, but it’s the first time in days it looks like a proper surf.

The standout of the whole run looks like Monday the 14th. The wind drops right out for the morning, with a light offshore from the NNE. The swell is a touch over 4ft, but the period jumps to 12 seconds – proper groundswell. The energy is moderate at 423. This is a clean, glassy window with real push behind it. This is your best chance for a decent session.

After that, it fades again. The rest of the second week is mostly small, with moderate cross-offshore winds and weak, short-period swell. There’s another long-period pulse on Wednesday the 23rd, but it’s tiny – only 2ft to 2ft with a 16-second period. That’s just not enough size to make the reef work.

The only other flicker of hope is Sunday the 20th afternoon. It’s small, around 3ft, but the winds are offshore and the period is a workable 9 seconds. It’s a long way off, but it could be a clean, small-wave option if the forecasts hold.

So, bottom line – don’t get too excited for the next week and a half. The window on Monday morning looks like the one to clear your schedule for. Everything else is just waiting for the ocean to settle down.

Stay patient, and keep an eye on that Monday forecast.

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.
