in Iceland: when to go?
océanique subpolaire climate
L'Islande jouit d'un climat océanique subpolaire étonnamment tempéré grâce au Gulf Stream. Contrairement aux idées reçues, les températures restent modérées toute l'année, oscillant entre -1°C en hiver et 13°C en été. Le pays connaît deux saisons distinctes : un hiver long et venteux de novembre à mars avec seulement 4-5h de jour en décembre, et un été court mais lumineux de juin à août avec près de 20h de clarté quotidienne. L'automne et le printemps servent de transitions rapides. Les précipitations sont fréquentes mais rarement intenses, alternant entre pluie et neige selon l'altitude et la saison. Pour votre voyage, privilégiez juin à août pour profiter des routes praticables, des lupins en fleurs et des macareux. L'hiver offre ses aurores boréales mais limite les déplacements. Le temps change rapidement : préparez-vous à toutes les conditions en une même journée !
