Best season and best time to dive on Qeshm
Spring is generally the sweet spot — calm water, strong visibility, and comfortable air temperature make it ideal for both recreational diving and freediving practice. Summer brings warmer water for longer sessions, but the air temperature climbs sharply. Early morning is usually the best time of day: wind and surface chop tend to be lowest, which means better visibility underwater. The table below breaks conditions down month by month so you can plan your trip around them.
