Visitor numbers are far lower during off-season and will almost feel like you have the whole island to yourself. You'll avoid the busy crowds and get the chance to explore further as well as snapping up the perfect photo opportunity without anyone getting in your way!
Accommodation and travel - during off-season, accommodation and travel is considerably less expensive and you're more likely to find some great deals without having to break the bank.
You might think the cooler months are a time for the islands to go into hibernation, but that simply isn't the case. You'll find a wide variety of winter wildlife and the chance to soak up lots of revitalising beach walks - just make sure to wrap up warm though!
The night skies
Longer nights and the lack of light pollution make the islands a fantastic location to explore the stars.
And just maybe... the Northern Lights
You're more likely to see the Aurora Borealis illuminate the night sky between October - March.
