At this time, Cheapflights has noticed price decreases for many domestic flights due to COVID-19. Travel is not necessarily recommended at this time, and flights may be prone to cancellation: please check with local authorities in both Oxford and Florence for travel alerts, and be sure to review the airline's cancellation policy and travel advisories before booking.

You can imagine temperatures to be in the 33 °C range in July. The weather in Florence is generally hotter than Oxford's. As flight availability is subject to become more limited as peak season approaches it is ideal to book in a timely manner.
