May in Portugal typically marks the transition from spring to summer, offering pleasant temperatures and sunshine across most of the country. While specific conditions will vary by region and elevation, generally, visitors can anticipate daytime highs ranging from the high teens to the low twenties Celsius, with cooler evenings. Coastal areas are often moderated by the Atlantic Ocean, leading to slightly lower temperatures than inland regions, which can experience warmer days. Rainfall becomes less frequent compared to the preceding months.

Packing appropriate clothing, booking accommodations with suitable amenities, and planning outdoor activities are all influenced by anticipated weather conditions. Historically, May has been a popular time to visit due to the agreeable climate combined with fewer crowds than the peak summer months.
