Quick answer: The best time to visit Portugal is spring (April–June) and autumn (September–October) — warm, sunny and less crowded than peak summer.
Portugal is a year-round destination, but the shoulder seasons give the best balance of weather, prices and crowds.
Spring (Apr–Jun) — best overall
Warm days, wildflowers and fewer crowds, ideal for cities and the coast.
Summer (Jul–Aug) — beaches & heat
Hot and busy, especially the Algarve; book ahead and expect peak prices.
Autumn (Sep–Oct) — great value
Warm sea, the wine harvest and the best surf, with thinner crowds.
Winter (Nov–Mar) — mild & cheap
Mild and rainy in the north; the Algarve and Madeira stay pleasant and quiet.
