How daylight hours swing across the UK year

London sits at 51.5° north. That latitude guarantees a 9-hour gulf between the June and December daylight totals. The UK stretches from Cornwall to Shetland, so the further north you go, the more extreme the swing. Even within England, the difference is sharp.

The UK’s westernmost point (Belleek, County Fermanagh) and easternmost point (Lowestoft, Suffolk) have a solar time difference of about 32 minutes, yet they share the same clock. That is why the sun can feel “late” to rise in the west and “early” to set in the east.

Shortest day: December solstice in London

The winter solstice in 2026 falls on 21 December.

  • Sunrise: 08:03
  • Sunset: 15:53
  • Daylight: 7 hours 50 minutes

The sun barely climbs above the horizon. For comparison, Edinburgh gets about an hour less daylight on the same date. Reduced winter daylight is linked to Seasonal Affective Disorder (SAD), a type of depression that follows the seasonal light pattern. Some workplaces provide light boxes during the darker months.

Longest day: June solstice in London

The summer solstice in 2026 falls on 21 June.

  • Sunrise: 04:42
  • Sunset: 21:21
  • Daylight: 16 hours 39 minutes

That is more than twice the daylight of December. Scotland experiences even lighter summer evenings, and much darker winter mornings, than southern England.

How BST shifts sunrise and sunset on the clock

British Summer Time (BST) moves the clock forward by one hour from the last Sunday in March to the last Sunday in October.

In 2026: - BST starts: Sunday 29 March (clocks go forward at 01:00 to 02:00) - BST ends: Sunday 25 October (clocks go back at 02:00 to 01:00)

The shift pushes both sunrise and sunset one hour later on the clock. Lighter evenings, later sunrises. In winter, GMT (UTC+0) keeps the sun rising at a reasonable hour: 08:03 instead of 09:03.

Regional variation: Scotland vs southern England daylight

Scotland sits at roughly 56-60° north. In summer, the far north gets nearly 19 hours of daylight, with twilight lasting most of the night.

Southern England (London, Brighton, Cornwall) gets about 8 hours in winter and 16.5 hours in summer. The difference matters for outdoor events, school runs, and commute safety. Farmers and outdoor workers in Scotland often oppose permanent BST because of dark winter mornings. Livestock routines are tied to solar time, not clock time.
