The climate can be classified as Oceanic in the north and Mediterranean in the south. Portugal is one of the warmest European countries, the annual temperature averages in mainland Portugal are 13 °C (55 °F) in the north and 18 °C (64 °F) in the south. The Madeira and Azores Atlantic archipelagos have a narrower temperature range. Generally, spring and summer are sunny, whereas autumn and winter are rainy and windy. Extreme temperatures occur in Northeastern parts of the country in winter (where they may fall to -15 °C) and Southeastern parts in summer (where they can soar up to 45 °C). Sea coastal areas are milder, temperatures varying between -2 °C in the coldest winter mornings and 37 °C in the hottest summer afternoons. Absolute extremes registered so far have been -23 °C in Serra da Estrela and 48 °C in the Alentejo region.

Mainland Portugal is split by its main river, the Tagus. The northern landscape is mountainous in the interior areas, with plateaus indented by river valleys. The south, between the Tagus and the Algarve (the Alentejo), features mostly rolling plains and a climate somewhat warmer and drier than in the cooler and rainier north. The Algarve, separated from the Alentejo by mountains, enjoys a Mediterranean climate much like southern Spain. Snow falls occasionally (on some cold winter days) in the northern interior of the country, from October to May. However, it is a very rare event in the south. The coast registers snow usually once in five or six years.

The islands of the Azores are located in the Mid-Atlantic Ridge whilst the Madeira islands were formed by the activity of an in-plate hotspot, much like the Hawaiian archipelago. Some islands have had volcanic activity as recently as 1957. Portugal's highest point is Mount Pico on Pico Island. It is an ancient volcano measuring 2,351 m (7,713 ft). Mainland Portugal's highest point is Serra da Estrela, measuring 1993 m (6,558 ft).

Portugal's Exclusive Economic Zone, a seazone over which the Portuguese have special rights over the exploration and use of marine resources, has 1,727,408 km². This is the 3rd largest Exclusive Economic Zone of the European Union and the 11th in the world.

Conservation areas of Portugal include one national park (Parque Nacional), 12 natural parks (Parque Natural), 9 natural reserves (Reserva Natural), 5 natural monuments (Monumento Natural), and 7 protected landscapes (Paisagem Protegida), ranging from the Parque Nacional da Peneda-Gerês to the Parque Natural da Serra da Estrela to the Paul de Arzila.
