Climate

Portugal presents in general a mild climate, with medium daily temperatures between 8ºC to 18ºC in the winter and 16ºC to 30ºC in the summer. However, the differences between north and south, the coast and the interior areas are quite evident at certain periods of the year.
The north registers the highest precipitations and the lowest medium temperatures year-round and the interior areas the highest temperatures. The south side of Tagus River presents Mediterranean influences, having very hot and prolonged summers, and short winters with low rainfall. Madeira island has a typical Mediterranean climate with mild and pleasant temperatures year-round, whereas the Azores islands present a mild maritime climate with abundant rainfall.
