Lisboa Weather & Climate Guide 2026

When to visit Lisboa: real monthly data on temperature, rain, and crowds — not vibes.

Lisboa (Lisbon) is Portugal's sun-drenched capital, a city of seven hills overlooking the wide mouth of the Tagus River where it meets the Atlantic. One of Europe's oldest and most atmospheric capitals, Lisbon blends Moorish alleyways, Manueline monasteries, baroque palaces, and cutting-edge contemporary culture into a tapestry of faded grandeur and vibrant renewal. The city's golden Age of Discoveries legacy is visible in every azulejo-tiled facade, and audible in the mournful strains of fado drifting from Alfama's cobbled lanes.

Lisbon enjoys a warm Mediterranean climate (Köppen classification Csa) with over 2,800 hours of sunshine annually, making it Europe's sunniest capital. Summers are hot and dry (June–September), with temperatures regularly exceeding 30°C in July and August. Winters are mild and damp (November–February), with temperatures rarely dropping below 8°C. The Atlantic influence moderates extreme heat and occasionally brings storms in autumn and winter. Spring (March–May) and early autumn (September–October) offer ideal conditions with warm temperatures, minimal rain, and fewer crowds than the peak summer months.

Best time to visit

Recommendation

Best: March–June, September–October

Avoid: August (peak summer heat, maximum crowds, highest prices); January–February (wettest months, some closures)

Peak Season: July–August

Notes: May is widely considered the finest month to visit: wildflowers carpet Sintra's hills, temperatures are comfortable for walking, and the city is alive but not overwhelmed by tourists. September and October offer warm sea temperatures (around 20°C/68°F) at the Atlantic beaches, significantly thinner crowds, and lower hotel rates. June is popular for the Festas de Lisboa festivities around Santo António (June 12–13).
