The best time to visit Chonchi is during the summer months, from December to March, when the weather is most favorable for exploring.
During these months, you'll experience warmer temperatures and less rainfall, making it ideal for outdoor activities like exploring the "Churches of Chiloé," a UNESCO World Heritage site, and visiting the Muelle de las Almas (Dock of Souls) in the nearby town of Cucao. The longer daylight hours also provide more time to enjoy the natural beauty of the Chiloé Archipelago. This period is particularly good for families looking for pleasant weather for sightseeing and excursions.
Should you prefer a quieter experience with fewer crowds, the shoulder seasons of spring (October-November) and autumn (April-May) also offer agreeable weather. While there might be a bit more rain, you'll find a more relaxed pace and still be able to enjoy many of Chonchi's attractions, including its charming stilt houses known as palafitos.
