Considerations

Rain occurs 10 days of the month with sudden afternoon downpours lasting 30-45 minutes - can disrupt outdoor plans between 2-5pm daily

Essential Tips

What to Pack

Waterproof jacket with breathable lining - May's 89mm (3.5 inches) of rain comes in sudden 30-45 minute bursts, not all-day drizzle

Comfortable waterproof walking shoes with good grip - Porto's cobblestones become slippery when wet from frequent showers

Layered clothing for 9°C (16°F) temperature swings - t-shirt and light sweater combination works for 11°C (52°F) mornings to 20°C (68°F) afternoons

Compact umbrella that fits in day bag - essential for sudden afternoon downpours while exploring outdoor attractions

SPF 50+ sunscreen despite variable weather - UV index reaches 8 and Portuguese Atlantic light reflects strongly off white buildings

Light scarf or windbreaker - Atlantic winds create wind chill effect along Douro riverfront and Foz coastal areas

Quick-dry fabric clothing - 70% humidity means cotton takes hours to dry if caught in rain

Portable phone charger - frequent weather app checking and GPS use during route changes drains batteries faster

Cash in small denominations - traditional markets and tascas often don't accept cards, especially during busy spring season

Comfortable day pack with water-resistant zippers - protects electronics and documents during unexpected weather changes

Insider Knowledge

Locals call May 'Maio das Rosas' and time outdoor activities between 10am-2pm when rain is least likely - restaurants open terrace seating during these prime hours

Book dinner reservations for 7:30pm instead of 8:30pm in May - restaurants fill up earlier as tourists avoid later outdoor dining due to temperature drops

Use the 'Via Navegável do Douro' water taxi during rain - costs same as metro (€1.60) but provides covered transport with scenic views when weather turns

Shop at Rua de Santa Catarina covered galleries during afternoon rain hours - local boutiques offer better prices than tourist-focused shops and provide weather shelter

Avoid These Mistakes

Assuming rain means staying indoors all day - May showers are brief and intense, then sun returns creating perfect post-rain photography light

Booking only morning activities - afternoon rain (2-5pm) actually creates ideal timing for port wine cellars, museums, and covered market visits

Packing summer clothes expecting warm weather - 11°C (52°F) evening temperatures require layers even when days reach 20°C (68°F)
