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 Belfast and Syros 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.
With an average temperature of 28 °C, peak weather can be found in August. As a traveller, expect to see changes in flight prices during that period. The temperatures in Syros are hotter than in Belfast.
