The best time to visit Oliveira is during the cooler, drier months from April to September.
This period avoids the intense heat and heavy rainfall of the summer months (December to February), making it much more comfortable for exploring the town and surrounding area. You'll find pleasant temperatures and plenty of sunshine, superb for outdoor activities and sightseeing.
Couples looking for a relaxing getaway will appreciate the mild weather, which is ideal for strolling through the town's historic centre, visiting local churches, and enjoying the natural beauty of the region without the discomfort of high humidity or frequent downpours.
Families travelling with children will also find these months more suitable.
