Lagos in May
Late spring. Smaller, cleaner conditions and water finally past the winter low. One of the best-value months: warm enough, uncrowded, and the schools are not yet at summer capacity.

Lagos
Lagos's south coast is least reliable in summer and can go flat for days; autumn to spring wraps more swell in. Water is the warmest in the country and wind is light all year, so it works as a mixed surf-and-beach trip in any month, with west-coast day trips as the backup when the south goes quiet.
