The superb location of Château Latour, just 300 metres from the Gironde river, gives it its special character and tempers any extreme weather conditions, particularly spells of severe cold or frost, as for example in 1991.
There are two factors that have a benign influence: • the proximity of the Atlantic, bringing the mildness of an ocean climate. • the immediate proximity of a large mass of water in the form of the estuary, protecting against the possible cold spells early in the growth cycle and also enabling earlier ripening of the grapes that can be valuable as the harvests approach. The climate in the Médoc is very variable, which is why each vintage is so different; however, in general terms, the climate may be characterized as follows: • a mild, wet winter with some cold spells, • the spring usually has two phases, the first cold and damp, the second warmer but often rainy, • a hot summer, frequently rainy until mid-July and then drier. Day and night time temperatures are generally more contrasted in August, thereby accelerating the ripening of the grapes while preserving their aromatic freshness, • the beginning of the autumn is usually sunny with cooler temperatures.
