For the best weather and to experience Alcobaça at its most pleasant, the ideal time to visit is during spring (April to June) or early autumn (September to October).During these months, you'll find comfortable temperatures, typically ranging from 15°C to 25°C, with less rainfall than in winter. This makes it great for exploring the Alcobaça Monastery and the town's other historical sites on foot, as well as enjoying outdoor dining.Couples looking for a romantic and relaxed trip will particularly appreciate late spring, when the gardens are in bloom and the days are long, allowing for leisurely strolls and evening meals. The town is generally less crowded than in the peak summer months, offering a more intimate experience.Families travelling with children might find early autumn appealing. The weather is still warm enough for comfortable sightseeing, and the summer crowds have thinned out, making visits to popular attractions more manageable.
