Travel is not necessarily recommended at this time, and flights may be prone to cancellation: please check with local authorities in both Cardiff and Tucson for travel alerts, and be sure to review the airline's cancellation policy and travel advisories before booking.

The rainfall in Cardiff is generally less than the rainfall in Tucson. This will continue over the next 10 days.
You can imagine temperatures to be in the 39 °C range in June. The weather in Tucson is generally hotter than Cardiff's. As flight availability is subject to become more limited as peak season approaches it is ideal to book in a timely manner.
