Porto climate — 2,500 sunshine hours, Atlantic mild
Porto has an Atlantic climate: mild winters (9-12°C), warm but not hot summers (20-22°C), and rain concentrated from November to March. The city gets about 2,500 sunshine hours per year — more than London or Amsterdam, less than Lisbon or Malaga. Summers are cooler than southern Portugal because the Atlantic keeps temperatures in check. You’ll rarely see 35°C here.
The trade-off is winter rain. November through February averages 12-15 rain days per month. Pack a waterproof jacket if you’re coming between October and March. The upside: winter rents drop 20-30% and the city empties of tourists.

Best months for remote workers
May through September is prime time. Temperatures stay between 16-22°C, rain days drop to 2-9 per month, and daylight stretches past 21:00 in June and July. You can work from outdoor terraces, walk along the Douro after work, and hit Foz do Douro beach on weekends.
June and September are the sweet spot. Warm enough for outdoor living (19-20°C), but tourist crowds are thinner than July-August. Accommodation is 15-20% cheaper than peak summer. September still has 8.5 hours of sunshine per day.
July and August bring the warmest weather (21-22°C) but also peak tourism. Ribeira and Rua das Flores get packed. Prices jump for short-term rentals. If you come in peak summer, book accommodation in Bonfim or Campanhã — locals live there, tourists don’t.
October through April is off-season. Rain picks up, temperatures drop, but the city is quiet and rents are low. Good months if you prefer indoor-focused work and don’t mind grey skies. Porto’s coworking spaces and cafes stay busy year-round.
What to pack
May-September: Light layers. A cotton hoodie for cooler evenings near the river. Porto gets breezy off the Atlantic even in summer — 25°C in Bonfim can feel like 20°C in Foz do Douro. Sunscreen for outdoor work sessions.
October-April: Waterproof jacket (not an umbrella — Porto wind destroys umbrellas). Warm layers for 10°C mornings. Waterproof bag or sleeve for your laptop — you’ll get caught in rain walking between cafes.
Year-round: Good walking shoes with grip. Porto is built on hills and the cobblestones get slippery when wet. Calçada portuguesa (traditional stone pavement) is beautiful but treacherous in rain.
