The situation around Monticiano

Rain on a good share of the days around Siena over the last seven days. 3BMeteo tops the 14-day ranking for the Monticiano area, but by a minimal margin of under 3 points over the second-placed service. On temperatures alone, however, Meteo.it is more accurate in the provincial capital's data. Little wind: light breezes on most days. Yesterday's report card reshuffled the order: the week's No. 2 finished No. 1. The top-ranked service is the same in nearby municipalities too (Murlo, Chiusdino). A curious detail: yesterday the service ranked last overall was among the two most accurate on the provincial capital's report card.
