The Lowdown
G’day, Rusty here. Looks like we’re in for a bit of a lean stretch at 23 Beach. The forecast shows some swell hanging around, but the wind and conditions just aren’t playing ball for most of the next couple of weeks. The water temp is sitting at 73°F, which is bang on average for this time of year, so that’s one small comfort.
Right now, through the rest of August and into early September, it’s a real mixed bag but mostly a frustrating one. Swell heights bob around from 1 ft to 5 ft, mostly from the NNW or NW, with periods mostly short around 6 to 10 seconds. The biggest issue is the wind – it’s cross-on or onshore nearly the whole time, with speeds from 9 mph up to 16 mph, making for chop and messy faces. The wave energy is moderate to strong in the bigger pulses, with readings like 480 on the 22nd of August morning, but it’s all wasted. Tuesday the 27th of August morning is the first real glimmer, with a 5 ft NNW swell, glassy wind, and the guidance saying “expect good surf conditions.” That’s your standout window, but it’s a brief one – the afternoon goes back to cross-on. Then Friday the 28th of August morning looks promising too, with 5 ft from the NW, zero wind, glassy conditions, and a solid energy reading of 380; that’s another chance at a clean session. After that, it’s back to onshore and cross-on winds, with a bit of a gap where nothing stands out through to the start of September.
The best on offer is definitely those two windows around the 27th and 28th of August. For a beginner spot like 23 Beach, the 5 ft to 5 ft swell is totally manageable, and with glassy or calm wind the waves will be clean. The swell direction is NNW to NW, which works for this exposed break. Just be aware that crowds are possible here, and the swell period is short (7-8 seconds), so don’t expect much push or shape – more of a fun, poppy wave for a longboard or foamie. If you can get out on the 27th morning or 28th morning, you’ll get the pick of it, but the rest of the period is pretty ordinary.
Rusty.

Information about the 23 Beach Surf forecast
The above surf forecast table for 23 Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 23 Beach can be found by selecting the local surf guide option on the grey menu. Our 23 Beach 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 (23 Beach) 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 23 Beach 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.
23 Beach is 11 km (7 miles) from the city of Casablanca. If you plan a holiday in Rabat to Casblanca, look for hotels and other accommodation in Casablanca. Casablanca has rooms for a wide range of budgets as well as car hire and transport links.
