Sassandra seasonal overview
Best Surf Season (January - April)
The opening four months of the year are Sassandra's most consistent window for clean surf. A robust South Atlantic high pressure ridge keeps the prevailing winds light and often westerly, and the long-period groundswell from the Southern Ocean is already pulsing at 10-12 seconds. January through April sees the highest percentage of ideal wind of the entire year, peaking at 62% in March, while the average swell height sits in the rippable 3-5ft (1-1.5m) range. Dry-season conditions, warm water around 27°C and limited rainfall create classic shoulder-high point surf, especially when the swell swings into the east-southeast to south-southeast window.
Fair Surf Season (October - December)
The autumn and early winter months are a transitional period. Swell sizes ease back from the June-August peak, but the arrival of the dry season in late November and December clears the air and pulls the wind around to the northwest more often. October can still produce punchy 4-5ft (1.2-1.5m) swell, while December's clean 3-4ft (1-1.1m) waves are smaller but far better shaped. Water temperatures climb above 28°C and the coast receives relatively little rain, making the fair season an excellent time for loggers and high-performance boards alike when a decent SSE groundswell fills in.
Low Surf Season (May - September)
From late spring through summer, the South Atlantic storm track is at its most active, pumping heavy swell toward the Gulf of Guinea. Average swell heights climb to a solid 5ft (1.5-1.6m) and periods stay in the powerful 12-second range, so there is certainly no shortage of ocean energy. However, this is also the height of the West African monsoon. Rainfall peaks in June at 11.4mm per day, and the wind fields are dominated by fresh south to southwest flow, which puts a lumpy, wind-affected surface on the waves. Only when a passing disturbance drags the wind into the W/NW quadrant does Sassandra show its true high-performance potential. In short: plenty of size, but patience is required.
