Solar evidence pack
This audit ties the page to a retained city route, exact coordinates, local timezone, a full-year daylight curve, twilight thresholds, and peer-city comparisons.

Practical read
Photography
1h 27m golden hour today
Best annual golden-hour day: Dec 21 — 1h 28m. Blue-hour total today: 18m.
Astronomy
365 true-darkness days
Longest astronomical-night entry: Jan 12 — 9h 45m. Use local cloud cover and moon phase separately.
Outdoor routine
12h 29m daylight today
Sunrise 6:30 AM and sunset 7:00 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.
Seasonal planning
0h 45m annual swing
June average 12h 30m; December average 11h 45m. This is the year-scale gap to check before travel or outdoor scheduling.
Travel comparison
10 retained peer curves
Lagos's closest daylight-pattern peers here include Singapore (0h 9m annual swing), Nairobi (0h 9m annual swing), Bangkok (1h 37m annual swing), Lima (1h 25m 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 includes
Latitude, longitude, solar elevation thresholds, atmospheric-refraction sunrise/sunset convention, Africa/Lagos 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 Africa/Lagos 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.
14h+ daylight days
0
Days at or above fourteen hours of sun.
10h-or-less days
0
Short-day entries at ten hours or below.

Year-round photographer planning
Combined morning + evening windows, computed for every UTC day of the year.
Twilight phases reference
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
Reference fields include Lagos's route, coordinates, timezone, daylight extremes, twilight windows, white-night counts, peer curves, evidence checks, and calculation boundaries.
Frequently asked questions
These are selected by latitude and annual daylight swing, not by the generic city list, so the comparison is tied to Lagos's actual solar profile.
