For most visitors, the best time to visit Comillas is during the late spring and summer months, particularly from June to September, when the weather is at its most pleasant.
During these months, you'll find warm, sunny days great for enjoying the town's beaches, like Playa de Comillas, and exploring its architectural gems. The temperatures are generally comfortable, making it ideal for walking around and visiting attractions such as El Capricho de Gaudí or the Palacio de Sobrellano. This period also sees the town at its liveliest, with more restaurants and shops open.
Families often find July and August particularly appealing due to the longer daylight hours and warmer sea temperatures, which are great for swimming and building sandcastles. The town also hosts various local events and festivals during the summer, adding to the holiday experience.
Couples looking for a slightly quieter, yet still warm, experience might prefer June or September. The weather is still excellent, but there are fewer crowds, allowing for more relaxed visits to sights and more intimate dining experiences.
