During March and April, Portugal transitions from winter to spring. Expect daytime temperatures to range from the mid-teens to low twenties Celsius (high fifties to low seventies Fahrenheit), with cooler nights. Rainfall decreases as spring progresses, though showers are still possible. Southern Portugal generally experiences warmer temperatures and more sunshine than the north.
These mild and increasingly sunny conditions make spring an ideal time to visit Portugal. The pleasant weather allows for comfortable exploration of historic cities, charming towns, and stunning coastal landscapes. Outdoor activities such as hiking, cycling, and watersports become more enjoyable. The spring season also coincides with the blossoming of wildflowers, adding vibrant colors to the countryside. Historically, this period also marked the beginning of the agricultural season, influencing cultural traditions and local festivals.
