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 Cardiff and Tours for travel alerts, and be sure to review the airline's cancellation policy and travel advisories before booking. For more information, please view our post on what to know about COVID-19 (coronavirus) and travel.
When travelling, it's generally smart to pack in preparation for rain or any other conditions that may arise. The rainfall in Cardiff is roughly less than Tours. You can assume this to be the case over the next 10 days.
With an average temperature of 26 °C, peak weather can be found in July. As a traveller, expect to see changes in flight prices during that period. The temperatures in Tours are hotter than in Cardiff.
