The best time to go to Callosa De Segura is during the spring (April to June) and autumn (September to October) months.During these periods, the weather is pleasantly warm and sunny, with average temperatures ranging from 68°F to 77°F (20°C to 25°C). This makes it ideal for exploring the town's historical sites, like the Church of San Martín and the Hermitage of San Roque, and for enjoying outdoor activities in the surrounding Sierra de Callosa mountains without the intense heat of summer. Couples and solo travelers will appreciate the comfortable conditions for walking through the town's narrow streets and enjoying outdoor dining.The summer months (July and August) can be very hot, with temperatures often exceeding 95°F (35°C), which might be less comfortable for extended sightseeing. However, if you enjoy very warm weather and spending time by a pool, this could still be an option.
