Mean temperature of each July and August — all days and nights of the month averaged together.
Data: monthly mean temperatures observed at Roma Ciampino, Rome's WMO reference station (archive begins October 1951; August 2026 still in progress). A few months are absent from the archive — notably 2015–2016 and 2018, plus scattered Augusts — and are shown as gaps bridged by a straight line rather than estimated. Station data, so values reflect Ciampino itself; central Rome runs slightly warmer.
