When does civil twilight start and end in London?

Civil twilight in London today runs 6:25 AM to 5:02 PM. It's the period when the sun is between -0.833° and -6° elevation; the brightest stars become visible at the dusk boundary.

What is the longest astronomical-night day of the year in London?

London's longest stretch of true astronomical darkness in 2026 is Dec 21 — 12h 2m. Astronomical twilight ends when the sun reaches -18° elevation; only beyond that do deep-sky targets become observable.

Are there white nights in London?

0 days without a civil-twilight bound, 0 without a nautical-twilight bound, 59 without an astronomical-twilight bound. On those days the sun never falls low enough for the named phase to occur, so true darkness disappears for that stretch of 2026.

City solar dossier

London daylight facts that are not generic

These rows bind the page to London's coordinates, local timezone, annual daylight spread, twilight availability, and peer-city curve rather than a reusable sunrise template.

Coordinate model

London is computed at 51.51°N, 0.13°W in Europe/London. The coordinate, not the country or timezone alone, controls the curve.

Annual daylight spread

8h 48m between Dec 18 (7h 50m) and Jun 17 (16h 38m).

Local-date snapshot

Today resolves to sunrise 7:01 AM, solar noon 11:44 AM, and sunset 4:26 PM.

Practical read

How to use this solar profile

Photography

2h 25m golden hour today

Best annual golden-hour day: Dec 21 — 2h 54m. Blue-hour total today: 27m.

Astronomy

306 true-darkness days

Longest astronomical-night entry: Dec 21 — 12h 2m. Use local cloud cover and moon phase separately.

Outdoor routine

9h 25m daylight today

Sunrise 7:01 AM and sunset 4:26 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.

Seasonal planning

8h 48m annual swing

June average 16h 33m; December average 7h 55m. This is the year-scale gap to check before travel or outdoor scheduling.

Travel comparison

10 retained peer curves

London's closest daylight-pattern peers here include Amsterdam (9h 7m annual swing), Berlin (9h 11m annual swing), Vancouver (8h 4m annual swing), Paris (7h 56m annual swing).

Civil-light risk

Full civil-twilight bound all year

Civil twilight uses -6°. White-night counts matter because dawn/dusk phases stop behaving like ordinary morning/evening windows.

Calculation boundaries

What this model can and cannot promise

What this model includes

Latitude, longitude, solar elevation thresholds, atmospheric-refraction sunrise/sunset convention, Europe/London local formatting, and a 365-day sweep for 2026.

What this model excludes

Mountains, skyline obstruction, sea horizon differences, weather, smoke, cloud cover, local legal definitions, aviation rules, and observer elevation.

When to verify elsewhere

Use official observatory, aviation, maritime, legal, or local almanac sources for high-stakes operations; this page is designed for planning, comparison, and general reference.

Why city pages differ

Two cities in Europe/London can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.

Seasonal daylight fingerprint

These values are derived from the same 365-day curve: threshold counts, fastest day-to-day change, the closest 12-hour balance, and monthly daylight averages.

White-night counts

0 days without civil-twilight bound, 0 without nautical-twilight bound, 59 without astronomical-twilight bound. On those days the sun never gets low enough for the named phase to occur, so true darkness disappears for that stretch.

Twilight phases reference

What each phase means

Solar elevation thresholds used on this page. All angles are measured from the true horizon at the city coordinate.

Sunrise / sunset · -0.833°
The sun's upper edge crosses the horizon. The negative value is atmospheric refraction (~34') plus the apparent solar disc radius (~16') — what almanacs call "official" sunrise/sunset.
Golden hour · 6° to -4°
Warm, low-angle light photographers and cinematographers plan around. Two windows per day — one in the morning, one in the evening.
Blue hour · -4° to -6°
Sky takes on deep, even blues; useful for cityscape photography because artificial lights and ambient sky balance.
Civil twilight · -6°
Brightest natural objects are still visible; outdoor activities don't need artificial light. Used in many legal definitions of dawn/dusk.
Nautical twilight · -12°
Horizon is just visible at sea, allowing celestial navigation; named for sailors taking sextant fixes.
Astronomical twilight · -18°
Sky is dark enough for deep-sky observation. After astronomical dusk and before astronomical dawn is when astrophotographers shoot.

Solar planning depth

What the London daylight curve means

This section turns the chart into readable planning context: latitude, seasonal range, monthly checkpoints, and how the curve should be used.

Solar fingerprint

London, United Kingdom is modeled at 51.51°N, 0.13°W in Europe/London. That coordinate pair drives every bar in the 2026 daylight curve.

Seasonal swing

The longest day is Jun 17 at 16h 38m; the shortest is Dec 18 at 7h 50m. The yearly range is 8h 48m, which makes this a large seasonal daylight profile.

Latitude context

London sits in the Northern Hemisphere high-mid latitude band. Latitude is the main reason two cities in the same timezone can have very different sunrise, sunset, and day-length patterns.

Monthly anchors

Useful checkpoints in this curve: Jan 15 8h 21m, Mar 15 11h 50m, Jun 15 16h 37m, and Sep 15 12h 40m. These anchors help readers see the shape of the year without reading all 365 bars one by one.

Today and twilight

Today in London, sunrise is about 7:01 AM, sunset about 4:26 PM, solar noon 11:44 AM, and daylight totals 9h 25m. Civil twilight runs 6:25 AM to 5:02 PM; golden hour windows are 6:39 AM to 7:51 AM and 3:36 PM to 4:48 PM.

Golden hour planning

Today's combined morning + evening golden hour totals 2h 25m. The longest combined golden hour day of 2026 is Dec 21 — 2h 54m. The shortest non-zero day is Mar 22 — 2h 9m. Year-round average is 2h 27m per day across days where a golden-hour window exists.

Twilight ladder

Nautical twilight today: 5:45 AM to 5:42 PM. Astronomical twilight today: 5:07 AM to 6:21 PM. The single longest stretch of true astronomical darkness in 2026 occurs on Dec 21 — 12h 2m. 306 days in 2026 include at least some astronomical darkness. 59 astronomical white-night days (the sun never reaches -18°), so true darkness disappears for that stretch.

Seasonal momentum

Fastest daily daylight gain: Jan 31 (+4m from the previous day). Fastest daily daylight loss: Aug 2 (-4m from the previous day). Closest 12-hour balance: Sep 25 at 12h 1m (+1m from 12h). Average-month anchors: June average 16h 33m is brightest, while December average 7h 55m is shortest. 131 days reach 14h+ daylight; 111 days stay at 10h or less.

Blue and civil light

Today's combined blue hour totals 27m. The longest combined blue-hour day is Jun 21 — 39m. Blue-hour average is 30m per usable day. The longest civil-twilight-only day is Jun 21 — 1h 36m. Civil twilight averages 1h 16m where both dawn and dusk edges exist.

Sunrise and sunset are approximations for planning and comparison. For legal, aviation, photography, or scientific use, verify with a local almanac or official observatory source.
