The best time to visit Ciboure is during the late spring and early autumn months, specifically May, June, and September. These periods offer pleasant weather, fewer crowds, and a good balance for enjoying both the coast and the inland attractions.May and June are wonderful for experiencing the region as it awakens for summer. The days are long, the temperatures are mild, typically ranging from 15°C to 22°C, and the natural landscape is at its most verdant. It's an excellent time for coastal walks, exploring the local markets, and enjoying outdoor dining without the peak season rush. Couples will particularly appreciate the quieter, romantic atmosphere before the main holidaymakers arrive.September offers a delightful continuation of summer, often referred to as "Indian Summer." The sea remains warm enough for swimming, and the average temperatures hover between 18°C and 25°C. The summer crowds have thinned, making it an ideal time for exploring the charming streets of Ciboure and Saint-Jean-de-Luz at a relaxed pace.
