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 Exeter and Nantucket 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, we recommend packing in preparation to handle common weather conditions. The rainfall in Exeter is typically greater than that of Nantucket. We can gather that this will continue over the next 4 days.
You can imagine temperatures to be in the 22 °C range in July. The weather in Nantucket is generally hotter than Exeter's. As flight availability is subject to become more limited as peak season approaches it is ideal to book in a timely manner.
