All Months
November through April brings dry skies and perfect temperatures. Mornings start cool around 60°F, afternoons warm to 75°F. The lake stays glassy until afternoon winds pick up. This is peak season, so book accommodation ahead. December and January get crowded with holiday travelers. March and April offer the best balance — great weather, fewer crowds, and lower prices. The rainy season runs May through October. Don't write it off completely — mornings often stay clear, and afternoon storms pass quickly. Plus, everything turns lush green and waterfalls cascade down the volcanic slopes. Just pack a good rain jacket and expect muddy trails.
