Alberobello Climate Patterns

Alberobello has a Mediterranean climate modified by altitude, and it is noticeably fresher than the coast in both directions.

Summer

July and August are hot, with highs usually between 29 and 32°C, but the plateau is dry and airy and the nights cool off properly — often to the high teens, which the coastal towns do not manage. Combined with the thermal mass of the trulli themselves, this makes Alberobello a more comfortable place to sleep in August than anywhere on the Adriatic shore below it.

Winter

Winter is genuinely cool by Puglian standards. January highs sit around 10 to 12°C, frost is common on clear nights, and light snow falls most years — rarely enough to settle for long, but enough that photographs of snow on the cones turn up every few winters.

Rain

Around 600 millimetres a year, concentrated between October and March. It matters more here than the figure suggests, because the aquifer and the cisterns are the only water the plateau has.

Spring and autumn

The best of the year. April to early June is green, mild and full of flowering almond and cherry; September and October are warm and dry with the vintage under way in the valley.

Why the wine works

The gap between hot days and cool nights is wider up here than on the coast, and that swing is what keeps acidity in the Verdeca and Bianco d'Alessano grown in the valley. It is the reason this small upland pocket makes white wine at all in a region otherwise known for heavy reds.

Wind

The plateau is exposed and a breeze is normal, which takes the edge off the summer heat and sharpens the winter cold.
