in Laos: when to go?
tropical humide climate
Le Laos offre un climat tropical humide rythmé par trois saisons distinctes. La saison sèche (novembre à mars) constitue la période idéale pour explorer ce joyau d'Asie du Sud-Est : températures agréables autour de 25-30°C, ciel dégagé et faible humidité créent des conditions parfaites pour visiter Luang Prabang, Vientiane ou les 4000 îles. La saison chaude (avril-mai) voit grimper le thermomètre jusqu'à 38°C avec une atmosphère étouffante, particulièrement dans la plaine du Mékong. Puis arrive la mousson (juin-octobre) qui apporte pluies torrentielles et forte humidité, transformant les pistes en bourbiers mais révélant une nature luxuriante spectaculaire. Les cascades atteignent alors leur apogée et les rizières verdoient magnifiquement. Privilégiez absolument novembre à mars pour un voyage optimal, avec décembre-janvier comme mois parfaits alliant fraîcheur matinale et chaleur douce l'après-midi.
