Latitude & Daylight at Taipeh

Taipeh sits at latitude 25.0°. At this latitude, daylight varies from approximately 13.6h in summer (solstice) to 13.6h in winter — a seasonal swing of 0.0h. The sun reaches a maximum altitude of 88.4° at summer solstice and a minimum of 41.5° at winter solstice. This mid-latitude profile is what shapes Taipeh's unique sunrise, sunset, and golden hour patterns year-round.

Taipei liegt nahe des Wendekreises des Krebses auf 25°N — dem Breitengrad, an dem die Sonne zur Juni-Sonnenwende genau 90° Höhe erreicht und zur Mittagszeit keinen Schatten wirft. Das Nationalmuseum für Naturwissenschaften der Stadt betreibt ein spezielles Sonnenobservatorium, das den Zenitdurchgang der Sonne verfolgt, und das Wendekreis-Wahrzeichen in Chiayi zieht jedes Jahr im Juni Tausende Besucher an, um das 'No-Shadow-Day'-Phänomen zu beobachten.

Golden Hour Photography at Taipeh

Golden hour at Taipeh occurs when the sun sits between −4° and 6° above the horizon, producing soft, warm, directional light ideal for portrait and landscape photography. At Taipeh's latitude, morning golden hour typically starts in the hour after sunrise and lasts approximately 28–40 minutes. Evening golden hour mirrors this before sunset. The longer twilight at this latitude gives photographers more time to capture the 'magic hour' compared to equatorial locations where the sun sets more steeply.

Taipei auf 25°N erlebt einen relativ bescheidenen saisonalen Tageslichtunterschied von 3,5 Stunden zwischen Sommer und Winter — der geringste unter den ostasiatischen Hauptstädten. Diese Äquatornähe bedeutet, dass die Goldenen Stunden der Stadt das ganze Jahr über konstanter sind als in höheren Breiten, wobei die Sonne in steileren Winkeln auf- und untergeht und klare, dramatische Schatten in Taipeis enger Gassenkultur erzeugt.

UV Exposure & Sun Safety at Taipeh

UV radiation at Taipeh peaks when the sun is highest in the sky — around solar noon. At 25.0° latitude, peak UV levels vary significantly by season: summer months see UV indices of 6–9 (high), while winter months typically register 1–3 (low). The World Health Organization recommends sun protection when UV index exceeds 3. At Taipeh's latitude, this threshold is exceeded for approximately 6–8 months per year, making sun awareness a year-round consideration for outdoor workers and athletes.

How We Calculate Solar Data for Taipeh

All solar calculations for Taipeh use the Jean Meeus Chapter 25 solar position algorithm with bisection iteration, accurate to ±1 minute for dates between 1901–2099. Sunrise and sunset times define the moment the upper limb of the sun appears on the horizon, accounting for atmospheric refraction. Daily data is calculated client-side from Taipeh's coordinates (25.0°, 121.6°) — zero server processing means your location data never leaves your device.
