Lisbon: 11 days.
Porto's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Porto's climate will still be more like its own today than any other large city's. The nearest other is Lisbon (Portugal).
+1.2°C
Mean temperature over the year
+1.8°C
Highest in the warmest month
+0.7°C
Lowest in the coldest month
-9%
Precipitation over the year
Under high emissions, the nearest is Lisbon (Portugal), and only in part.
Its own climate today is 1.9 σ away. How close the match is: 4.0 σ to the climate of Lisbon today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 2 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Where else Porto stands out
