Who It suits and why
Best for travellers who want warm seas and summer light without the August intensity. September is a sweet spot for the quietest islands – beaches have space again, tavernas have time to chat, and the days are still long enough for proper beach time. It suits couples, solo travellers, and families with pre-schoolers who are happy with a slower pace, swimming, walking, and low-key evenings.
It’s less ideal if you want lots of organised boat trips, beach clubs that stay open late, or daily direct flights from the UK. If you need a resort-style beach with sunbeds lined up and music all day, or you want to hop between several islands on frequent ferries, a larger or busier island with a longer season will give you more options.
