, with peak temperatures often exceeding 100°F (37.8°C). The daylight lasts for 15 hours in the majority of the state with intense sunshine.

Peak summer is as good a time as any for beachwear, but do not forget the sunscreen. Delaware sees thronging summer crowds due to significant temperature differences between the coast and interior.
