May is just gorgeous in Sri Lanka, in between both monsoons and also very quiet. Although if you want to combine a beach trip with seeing wildlife in Yala National Park, February until June is perfect, as water levels are low, so wildlife comes out to water holes. The blue whales come to play in March.
The Maldives are at their most heavenly between December and March, although keen marine-o-philes will love seeing the whale sharks between January and April.
Mozambique has a wonderfully long dry season from April-September.
Escape the European winter to those east coast beaches of Kenya and Tanzania, including Zanzibar and Mafia Islands, where the best times for bronzing are December, January and February.
Although many people think it is monsoon season in Sri Lanka in July, August and September, the northeast coast actually has its own monsoon in October to January. It is only the southwest that is hit by monsoon during these European summer school vacations. So head to the northeast during the eternally long ‘grandes vacances’.
If you are heading to the north of Madagascar, around Nosy Be, December is definitely the best time to hit the beach, with November usually pretty fine too. Combined with the fact that this is the month when baby lemurs come along too.
