The best time to visit Castro Verde is during the spring (April to June) and autumn (September to October) months.During these periods, the weather is pleasantly mild, with comfortable temperatures great for exploring the natural beauty of the Alentejo region. Spring brings blooming wildflowers, painting the landscape with colour, while autumn offers a golden hue to the plains and ideal conditions for outdoor activities. These seasons avoid the intense heat of summer and the cooler, wetter days of winter.For those interested in birdwatching, spring is particularly rewarding as it coincides with the breeding season of many species, including the Great Bustard, a highlight of the local wildlife. The milder temperatures also make walking and cycling through the Campo Branco (White Field) much more enjoyable.Travellers looking for a relaxed experience away from crowds will appreciate these shoulder seasons.
