Lagos in August
Still peak season and still small, but the first autumn pulses sometimes arrive late in the month. Water is at its warmest. The Sintra bodyboard world-tour event runs at Praia Grande in early September, on the shoulder of the month.

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.
