City solar dossier

Nairobi daylight facts that are not generic

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

Coordinate model

Nairobi is computed at 1.29°S, 36.82°E in Africa/Nairobi. The coordinate, not the country or timezone alone, controls the curve.

Annual daylight spread

0h 9m between May 15 (12h 3m) and Jan 1 (12h 12m).

Local-date snapshot

Today resolves to sunrise 6:11 AM, solar noon 12:16 PM, and sunset 6:21 PM.

Photographer signal

golden hour today 1h 23m; blue hour today 17m; longest golden-hour day Jun 21 — 1h 27m

Darkness and white-night risk

365 days include astronomical darkness; 0 civil white-night days and 0 astronomical white-night days are modeled in 2026.

Practical read

How to use this solar profile

Photography

1h 23m golden hour today

Best annual golden-hour day: Jun 21 — 1h 27m. Blue-hour total today: 17m.

Astronomy

365 true-darkness days

Longest astronomical-night entry: Mar 31 — 9h 36m. Use local cloud cover and moon phase separately.

Outdoor routine

12h 10m daylight today

Sunrise 6:11 AM and sunset 6:21 PM are the practical day-boundaries for school runs, work windows, and outdoor activity.

Seasonal planning

0h 9m annual swing

December average 12h 12m; May average 12h 3m. This is the year-scale gap to check before travel or outdoor scheduling.

Travel comparison

10 retained peer curves

Nairobi's closest daylight-pattern peers here include Singapore (0h 9m annual swing), Lagos (0h 45m annual swing), Lima (1h 25m annual swing), Bangkok (1h 37m 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, Africa/Nairobi 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/Nairobi can still have different daylight and twilight curves because the coordinate pair, especially latitude, drives the result.

Seasonal daylight fingerprint

How daylight changes through 2026

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.

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 Nairobi 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

Nairobi, Kenya is modeled at 1.29°S, 36.82°E in Africa/Nairobi. That coordinate pair drives every bar in the 2026 daylight curve.

Seasonal swing

The longest day is Jan 1 at 12h 12m; the shortest is May 15 at 12h 3m. The yearly range is 0h 9m, which makes this a low-variation tropical daylight profile.

Latitude context

Nairobi sits in the Southern Hemisphere tropical 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 12h 11m, Mar 15 12h 7m, Jun 15 12h 3m, and Sep 15 12h 6m. These anchors help readers see the shape of the year without reading all 365 bars one by one.

Today and twilight

Today in Nairobi, sunrise is about 6:11 AM, sunset about 6:21 PM, solar noon 12:16 PM, and daylight totals 12h 10m. Civil twilight runs 5:49 AM to 6:42 PM; golden hour windows are 5:58 AM to 6:39 AM and 5:52 PM to 6:34 PM.

Golden hour planning

Today's combined morning + evening golden hour totals 1h 23m. The longest combined golden hour day of 2026 is Jun 21 — 1h 27m. The shortest non-zero day is Mar 20 — 1h 20m. Year-round average is 1h 24m per day across days where a golden-hour window exists.

Twilight ladder

Nautical twilight today: 5:24 AM to 7:07 PM. Astronomical twilight today: 4:59 AM to 7:32 PM. The single longest stretch of true astronomical darkness in 2026 occurs on Mar 31 — 9h 36m. 365 days in 2026 include at least some astronomical darkness.

Seasonal momentum

Fastest daily daylight gain: Jul 28 (+1m from the previous day). Fastest daily daylight loss: Jan 6 (-1m from the previous day). Closest 12-hour balance: May 15 at 12h 3m (+3m from 12h). Average-month anchors: December average 12h 12m is brightest, while May average 12h 3m is shortest. 0 days reach 14h+ daylight; 0 days stay at 10h or less.

Blue and civil light

Today's combined blue hour totals 17m. The longest combined blue-hour day is Dec 21 — 17m. Blue-hour average is 17m per usable day. The longest civil-twilight-only day is Dec 21 — 45m. Civil twilight averages 43m 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.
