    Regional Diversity

    Diving in Portugal is possible year-round, but the best conditions vary by region. The main season for the mainland and archipelagos is from June to October. In the Azores, July to September is the peak time for pelagic encounters. Madeira offers comfortable diving throughout the year, with the warmest water (22°C-24°C) occurring in late summer and autumn. Mainland visibility is generally best in the summer months.
