Porto Weather Summary
Porto has an Atlantic climate — more rain than Lisbon, mild winters, warm summers. The Douro Valley (1–2 hours east) has a drier, more continental climate. June to September is Porto's driest and warmest period. The grape harvest season (September–October) is the best time for Douro Valley wine tours — the vineyards are at their most beautiful and the quintas are in full harvest mode.
When Are Porto Hotels Cheapest?
November through March offers 40–60% lower hotel prices than peak summer. April and October are 20–30% below peak. Book 2–3 months ahead for July and August.
