Sidi Bouzid - surf spot statistics

Best Surf Season (November - March)

The North Atlantic winter machine dominates this period, with the Azores High retreating and allowing deep low-pressure systems to barrel across the Atlantic. Sidi Bouzid reaps the rewards as consistent long-period groundswells from the NW and NNW light up the beach. Combined with an elevated occurrence of offshore winds from the east and southeast (E, ESE, SE, SSE), surf quality hits its peak. December and January deliver the most reliable combination of size (averaging 2.0m) and period (13+ seconds), while November and February maintain excellent power. March is a transition month; the swell remains solid, but the offshore wind window narrows slightly. Still, this is the prime window for charging Sidi Bouzid at its finest.

Fair Surf Season (October & April)

These shoulder months are marked by increasing or decreasing storm activity. October sees the first strong autumn swells arrive, with average heights of 1.6m and periods around 11.6s, though the wind is ideal only about 35% of the time. Occasional high-pressure setups can deliver glassy offshore days. April, on the other hand, is the fading tail of winter. Swell is still respectable (1.6m), but the strengthening sun and thermal gradients cause more onshore flow, dropping the ideal wind window to just 20%. Fun-sized waves are common, but the quality is less consistent than in the heart of winter.

Low Surf Season (May - September)

This is the quietest (and poorest) time of year for surf at Sidi Bouzid. The North Atlantic storm track shifts north, and the dominant trade winds blow from the NNE, creating persistent onshore conditions that ruin wave quality. Average swell heights drop to 1.2-1.4m with short, wobbly periods (8-10 seconds). The beach becomes a sea of bumps on most days. Only the rare eastward-moving cut-off low or tropical cyclone in the eastern Atlantic can salvage a session. June, July, and August are especially grim, with the wind being ideal less than 10% of the time. Summer is best for swimming, not surfing, at this spot.

May: Small Swell & Persistent Onshores

May signals the quiet season. Average swell height drops to 1.4m, and the period plummets to 10.1s, indicating more windswell than groundswell. The swell direction becomes overwhelmingly NNW, now contributing over 52% of the total, but with heights mostly in the 1-1.5m range. The wind is ideal only 14% of the time. The trade winds from the NNE and N howl over 47% of the month, creating messy, bumpy conditions. Occasional west or WNW swells can still produce fun-sized waves, but they are often accompanied by onshore flow. Surfers should lower expectations and look for the rare high-pressure setup that delivers a clean, small day. May is best saved for other pursuits.
