The climate in the Tuscan Maremma is characterized by the most complete variety, Mediterranean along the coast and more continental in inland areas. Temperatures and precipitations are influenced by the morphological conformation of the territory

The Maremma coast is characterized by a general mildness of the climate which diminishes as it proceeds towards the inland areas. We can however speak, for the whole of the Tuscan Maremma (Grossetana and Livornese), of a Mediterranean maritime climate, with mild and relatively rainy winters and cool, dry summers. The sea, with its mitigating action, determines these conditions: it is thanks to the sea, which is slow to warm up and cool down, that we owe the almost total absence of snowfall. In summer, the sea breezes help to soften the sultry summer days. Consequently, the temperature range between the cold and hot months is very low, of just 14 – 16 ° C: the average temperature of the coldest month – January – fluctuates between 4.8 ° C Massa Marittima and 9.4 ° C of Orbetello; that of the hottest month – July – between 22 ° C again in Massa Marittima and 25.3 ° C in Grosseto, the Maremma capital. Along the Maremma coast the thermometer rarely drops below zero on winter days and the maximum summer temperatures are around 33 ° C.

The average annual temperature in Maremma is about 16 ° C on the coast and undergoes a progressive decrease as it advances towards inland areas.

Inland, however, the climatic situation is different as the plain gives way to the hilly basin of the Metalliferous hills to the north, to the massif of Monte Amiata further south and the characteristic tuff gorges of the internal border of the Tuscan-Lazio Maremma: here the minimum temperatures of the coldest months are low and the summer maximums often touch the 40°C. The absence of high mountain groups in the hinterland means that the average rainfall in the coastal area even falls below 600 mm per year (Alberese). Further inland, the hills and the distance from the sea make this average rise to around 1000 mm. Especially during the summer months there is the lack of rainfall, which corresponds to an exactly low number of rainy days (0 in Orbetello, 1 in Suvereto, 2 in the other centers) and this constitutes an element favorable to seaside tourism, even if it represents a serious problem for agricultural crops that reach their maturity in the summer. The coastal strip of the Maremma LivorneseCosta degli Etruschi – is slightly more rainy, with average values between 600 and 700 mm per year, and a progressive increase in rainfall on the hills and mountains most exposed to the winds.
