What should I pack for a trip to Lisbon?
Packing recommendations depend on the season of your visit. Based on the climate data, pack lightweight, breathable clothing if visiting during the warm months (July is hottest at 22.7°C). For cooler months, bring layers and a warm jacket (January averages 11.6°C). A waterproof jacket or umbrella is recommended year-round as Lisbon receives 590.0mm of annual precipitation. Sun protection is important, especially during months with high UV index.
Lisbon's hills plus humidity make packing an art form. I showed up in July in linen — big mistake, the UV hits 9 and the city is essentially a suntrap. Pack breathable layers, a wide-brim hat, and the strongest SPF you own. My ideal window is mid-September to mid-October: 24°C, fewer crowds, and the Tagus breeze actually feels good. Skip February — it's wetter than you'd think. Tram 28 in summer is a sweatbox; ride it in November instead, when it's 16°C and the queues vanish.
