Warm days and little need for heavy layers

Zante in September suits travellers who want summer warmth but would rather not have very hot weather every day. Temperatures reach 25°C on 56% of days, so that level of warmth is common rather than guaranteed. Average night lows of 22.2°C mean evenings generally stay warm, making light clothing more useful than heavy layers. Humidity averages 72%, which can make the warmth feel less comfortable if you are walking around at midday. Keep more active plans for cooler parts of the day and leave room for shade breaks. Pack a light extra layer for cooler spells, but there is no reason to build your suitcase around cold evenings.

Good swimming conditions, with some rain to allow for

The sea is a strong reason to choose September: its average temperature is warm enough for swimming, rather than just a quick dip. The year-to-year range of 24°C to 26°C also points to reliably warm water, though it does not promise calm conditions on any particular day. Rain is the main compromise. About 6 days have measurable rain, so a completely dry holiday is not something to assume. That figure does not mean each rainy day is a washout, either. Keep swimming plans flexible, bring a light waterproof and avoid making every day depend on dry weather. September suits you best if an occasional change of plan would not spoil the trip.
