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 Southampton and Basel 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.
We forecast the temperature to be around the 26 °Cs in July, on average. The temperature in Basel is generally hotter than in Southampton. Book flights in a timely manner in correlation to your departure date.
