September closes the southern winter. The swell is still arriving and beginning to space out, the dry season holds, and the water starts back up from its 24° low.
What makes it the best month to travel rather than the best month for waves is everything around the surf. The weather is settled, the road from Maputo is dry, the village is between the two South African holiday waves, and the humpbacks that pass this coast on their migration are still around into the month. Tofo's reefs carry manta rays and whale sharks the whole year, so a flat day here has more to do than a flat day almost anywhere, and September is when the flat days are pleasant rather than wet.
The swell is a grade below June and July, which for most people is the right grade.
