Copán Ruinas in December

November through April offers the best weather — dry days with temperatures around 75°F and cool nights perfect for sleeping. December and January see the most tourists, especially around Christmas when Guatemalan families visit. Book accommodations early during these months. May through October brings daily afternoon rain, but here's the thing: morning hours stay mostly dry, perfect for exploring ruins. The landscape turns impossibly green, and hotel rates drop by 30%. Just pack a good rain jacket and waterproof camera bag. Avoid September and October if possible. These months see the heaviest rainfall, sometimes flooding the access roads. I've seen visitors stuck for extra days waiting for rivers to recede. The absolute sweet spot? Late February through early March. Tourist crowds thin out after Christmas, but the weather stays perfect. Plus, this timing lets you catch the spring bird migration — over 200 species pass through the valley. Come during the week if you can manage it. Weekends bring day-trippers from San Pedro Sula, turning the peaceful ruins into a school field trip atmosphere. Tuesday and Wednesday mornings offer the most solitude among the ancient stones.
