{{See also|Climate of Porto}}
Porto features a [[Mediterranean climate|warm-summer Mediterranean climate]] ([[Köppen climate classification|Köppen]]: ''Csb''), with influences of an [[oceanic climate]] (''Cfb''), common in the north of the [[Iberian Peninsula]].<ref>{{Cite book |url=https://books.google.com/books?id=0GNLDwAAQBAJ&q=oceanic+climate+influence+cfb+portugal&pg=PA14 |title=Passive Energy Strategies for Mediterranean Residential Buildings: Facing the Challenges of Climate Change and Vulnerable Populations |last1=Monge-Barrio |first1=Aurora |last2=Gutiérrez |first2=Ana Sánchez-Ostiz |date=9 February 2018 |publisher=Springer |isbn=9783319698830 |language=en |access-date=19 October 2020 |archive-date=2 October 2024 |archive-url=https://web.archive.org/web/20241002234750/https://books.google.com/books?id=0GNLDwAAQBAJ&q=oceanic+climate+influence+cfb+portugal&pg=PA14#v=snippet&q=oceanic%20climate%20influence%20cfb%20portugal&f=false |url-status=live }}</ref> As a result, its climate shares many characteristics with the warm, dry Mediterranean climates of southern Europe and the wet marine west coast climates of the North Atlantic, providing it warm, dry summers and mild, rainy winters. Cool and rainy days can, occasionally, interrupt the sunny weather. These occasional summer rainy periods may last a few days and are characterized by showers and cool temperatures around {{cvt|20|°C|0|abbr=on}} in the afternoon. The annual precipitation is high and concentrated in the winter months, making Porto one of the wettest major cities of Europe. However, long periods with higher temperatures and sunny days are frequent even during the rainiest months.

Summers are typically sunny, with average temperatures between {{cvt|16|and|26|°C|0|abbr=on}}, but can rise to as high as {{cvt|38|°C|0|abbr=on}} during occasional heat waves. During such heatwaves, the [[humidity]] remains quite low. Nearby beaches are often windy and usually cooler than the urban areas. Summer average temperatures are a few degrees cooler than those expected in more continentally Mediterranean-influenced Portuguese cities because of the oceanic influence.

Winter temperatures typically range between {{cvt|6|°C|0|abbr=on}} early in the morning and {{cvt|15|°C|0|abbr=on}} in the afternoon, but rarely drop below {{cvt|0|°C|0|abbr=on}} at night. The weather is often rainy for long stretches, although prolonged sunny periods do occur.
