Kos has a warm, Mediterranean climate, making it the perfect choice for summer holidays. August is blessed with the highest temperatures, but you can still soak up some sun and enjoy a dip in the sea later in the year.
A top Summer jolly destination, Kos weather in Summer is passionate, it's feisty, it's bloomin' boilin' with the celsius reaching high highs of 32°C through July and August and reach the lowest temp of 20°C in June. Get your beach bums on the sand and sizzle your way to that golden tan you've been dreaming about since you booked, last-minute bookers, that do include you.
If you're looking for toasty temps without the school holiday crowds, then you should deffo sneak a peak at an Autumn booking, the rainfall increases as the months tick over, so if you wanna maximise your jolly then look no further than September with temps still hitting 29°C. If you don't mind the rain then October and November still sit pretty between 12°C and 24°C, so still a chance at beach lazing and grub grazing on your Kos holidays.
Winter does a see a dip below the 10°C mark, but that doesn't mean you can't still enjoy mild weather, even in January the temps can hit 14°C - who says mild has to mean mid, you can still bag a banging jolly... maybe just keep a cardi handy incase.
A sightseers dream - when Spring has sprung on Kos you best believe the temps give you a reason to get outside and explore, we're talking highs of 24°C in May and much drier too. Finally time to dust off those hiking boots and take to the trails to keep your Insta-feed well fed for another couple months... or stick to the poolside and leave the boots at home, either way, it's gonna be a top-notch holiday to Kos.
