Practical read
How to use this solar profile
Photography
4h 13m golden hour today
Best annual golden-hour day: Jan 21 — 7h 1m. Blue-hour total today: 41m.
Astronomy
220 true-darkness days
Longest astronomical-night entry: Dec 21 — 12h 56m. Use local cloud cover and moon phase separately.
Outdoor routine
7h 34m daylight today
Sunrise 9:24 AM and sunset 4:58 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.
Seasonal planning
17h 2m annual swing
June average 20h 51m; December average 4h 22m. This is the year-scale gap to check before travel or outdoor scheduling.
Travel comparison
10 retained peer curves
Reykjavík's closest daylight-pattern peers here include Anchorage (13h 55m annual swing), Stockholm (12h 32m annual swing), Tromsø (24h annual swing), Moscow (10h 33m annual swing).
Civil-light risk
65 civil white-night days
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, Atlantic/Reykjavik 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 Atlantic/Reykjavik can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.

White-night counts
65 days without civil-twilight bound, 111 without nautical-twilight bound, 145 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.

What the Reykjavík 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
Reykjavík, Iceland is modeled at 64.15°N, 21.94°W in Atlantic/Reykjavik. That coordinate pair drives every bar in the 2026 daylight curve.
Seasonal swing
The longest day is Jun 20 at 21h 9m; the shortest is Dec 20 at 4h 7m. The yearly range is 17h 2m, which makes this a polar/extreme daylight profile.
Latitude context
Reykjavík 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 5h 25m, Mar 15 11h 42m, Jun 15 21h 2m, and Sep 15 13h 4m. These anchors help readers see the shape of the year without reading all 365 bars one by one.
Today and twilight
Today in Reykjavík, sunrise is about 9:24 AM, sunset about 4:58 PM, solar noon 1:11 PM, and daylight totals 7h 34m. Civil twilight runs 8:29 AM to 5:53 PM; golden hour windows are 8:49 AM to 10:56 AM and 3:26 PM to 5:32 PM.
Golden hour planning
Today's combined morning + evening golden hour totals 4h 13m. The longest combined golden hour day of 2026 is Jan 21 — 7h 1m. The shortest non-zero day is Sep 20 — 3h 4m. Year-round average is 3h 54m per day across days where a golden-hour window exists.
Twilight ladder
Nautical twilight today: 7:31 AM to 6:51 PM. Astronomical twilight today: 6:35 AM to 7:46 PM. The single longest stretch of true astronomical darkness in 2026 occurs on Dec 21 — 12h 56m. 220 days in 2026 include at least some astronomical darkness. 65 civil-twilight white-night days in 2026 (the sun stays above -6° all night). 145 astronomical white-night days (the sun never reaches -18°), so true darkness disappears for that stretch.
Seasonal momentum
Fastest daily daylight gain: Jan 28 (+7m from the previous day). Fastest daily daylight loss: Jul 22 (-7m from the previous day). Closest 12-hour balance: Sep 25 at 11h 59m (-1m from 12h). Average-month anchors: June average 20h 51m is brightest, while December average 4h 22m is shortest. 154 days reach 14h+ daylight; 137 days stay at 10h or less.
Blue and civil light
Today's combined blue hour totals 41m. The longest combined blue-hour day is May 19 — 2h 52m. Blue-hour average is 49m per usable day. The longest civil-twilight-only day is May 19 — 4h 51m. Civil twilight averages 2h 4m 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.

- Today, the evening golden hour in Reykjavík runs 3:26 PM to 5:32 PM; the morning window is 8:49 AM to 10:56 AM. Combined total today is 4h 13m. Across 2026, the longest combined golden-hour day is Jan 21 — 7h 1m.
- When does civil twilight start and end in Reykjavík?
- Civil twilight in Reykjavík today runs 8:29 AM to 5:53 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 Reykjavík?
- Reykjavík's longest stretch of true astronomical darkness in 2026 is Dec 21 — 12h 56m. Astronomical twilight ends when the sun reaches -18° elevation; only beyond that do deep-sky targets become observable.
- Are there white nights in Reykjavík?
- 65 days without a civil-twilight bound, 111 without a nautical-twilight bound, 145 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.
Comparable daylight curves
These are selected by latitude and annual daylight swing, not by the generic city list, so the comparison is tied to Reykjavík's actual solar profile.
