Sidi R'bat - surf spot statistics

Best Surf Season (October – March)

The North Atlantic engine fires up in October, and Sidi R'bat feels the full force of the winter swell window. Average wave heights hover around 1.7–2.1m with long-period energy (11–13s) from the NW and WNW – the sweet spot for this west-northwest-facing beach. The percentage of ideal offshore wind (from the E through SSE quadrants) is at its annual peak during these months, reaching 51% in December. However, it's not a guaranteed glass-off every day; strong low-pressure systems often drag onshore NW winds across the lineup, especially following a cold front. When the synoptic setup aligns – a deep Atlantic low spinning far to the northwest, a ridge of high pressure building over the Iberian Peninsula, and light easterly flow filtering down the Moroccan coast – Sidi R'bat delivers pumping, long-period groundswell with clean, offshore conditions. That's when the waves here are truly firing.

Fair Surf Season (April & September)

These transitional months offer a mixed bag. April sees average swell heights drop to 1.9m and periods shorten to 10.9s, while the wind is only ideal 11% of the time. The dominant swell shifts more NNW, which still wraps in nicely, but the wind becomes a constant battle – the onshore NW-WNW breeze kicks in hard, making conditions choppy unless a rare easterly surge aligns. September marks the slow uptick in swell energy after the summer lull, with average heights of 1.4m and periods of 10.1s. While the number of storm-generated swells increases, the wind remains largely onshore (ideal just 7% of the time). Occasional early-season cold fronts can deliver a clean pulse of WNW swell with light offshore winds, offering short but quality windows. These months require patience and a weather-watching mindset.

Low Surf Season (May – August)

Summer at Sidi R'bat is a frustrating time for surfers seeking quality. The North Atlantic storm track retreats north, leaving the spot dominated by weak, short-period NNW swell generated by the persistent trade winds. Average wave heights drop to 1.4–1.7m, and period values sink below 9s – often in the choppy, weak range. To make matters worse, the onshore regime of NW-WNW winds locks in from late morning through the day, with ideal offshore wind occurring a mere 2–5% of the time. The result is often bumpy, disorganized waves that are better suited for longboards or a day off. The few surfable moments come on early summer mornings before the wind picks up, or during rare pulses of longer-period background swell from a distant hurricane. But for most surfers, this is the season to travel or explore other spots with more reliable summer trade-wind setups.

April: Chop & Chance

April is a tricky month at Sidi R'bat. Swell heights average 1.9m with a period of 10.9s – still surfable but with less punch than the winter months. The dominant swell direction shifts further north: NNW now accounts for a massive 46.7% of the energy, while NW holds at 27.9%. This more northerly angle still works, but the winds become a major obstacle. Ideal offshore conditions occur only 11% of the time – the lowest since the previous summer. The onshore trade wind machine is in full swing, with NW winds at 30.4%, WNW at 20.8%, and W at 11.4%. The result is often a choppy, bumpy surface that degrades even decent swell. The few quality sessions come when a late-season cold front passes, swinging winds briefly to the east before the next front arrives. April is for the dedicated surfer who is willing to watch the charts closely and pounce on short weather windows. A longboard can still find fun in the smaller, cleaner conditions, but don't expect consistency.
