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.
