There is never a bad time to visit the United Kingdom, but for the most reliable weather come during the summer months (June-August) when the days are long and warm. Temperatures have been known on occasion to nudge 30°C (86°F), sometimes higher, but the threat of rain is ever present - pack waterproofs as well as the sunscreen. The southeast of England is generally sunnier and warmer than the rest of the United Kingdom, but resorts along the coast get crowded during the summer.

The United Kingdom is arguably at its most beautiful during the autumn months (September-November), when rural landscapes take on brown, red and pink hues as the leaves lose their pigment. Scotland and the north of England bear the brunt of winter (November-March), but snow occasionally blankets much of the United Kingdom bringing with it travel chaos. The mercury has been known to dip to -10°C (14°F), but those kind of temperatures are rare.

Waterproofing throughout the year. Warm clothing is advisable at all times, and is essential for any visits to upland areas.
