Latitude & Daylight at A Coruña

A Coruña sits at latitude 43.4°. At this latitude, daylight varies from approximately 15.2h in summer (solstice) to 15.2h in winter — a seasonal swing of 0.0h. The sun reaches a maximum altitude of 70.1° at summer solstice and a minimum of 23.2° at winter solstice. This mid-latitude profile is what shapes A Coruña's unique sunrise, sunset, and golden hour patterns year-round.

A Coruña sits directly on the centerline of the August 12, 2026 total solar eclipse — the longest totality (1 minute 58 seconds) of any major city in the path. The city's Tower of Hercules, a UNESCO World Heritage Roman lighthouse dating from the 1st century, has watched over this Atlantic coastline for nearly 2,000 years and will witness the Moon's shadow sweep across the Bay of Biscay.

Golden Hour Photography at A Coruña

Golden hour at A Coruña occurs when the sun sits between −4° and 6° above the horizon, producing soft, warm, directional light ideal for portrait and landscape photography. At A Coruña'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.

At 43.4°N on Spain's northwestern Atlantic coast, A Coruña's sun path is shaped by the Cantabrian Sea: summer sunsets linger past 10 PM over the water, creating extended golden hours that attract photographers to its glass-fronted Paseo Marítimo — the longest seaside promenade in Europe at over 13 km.

UV Exposure & Sun Safety at A Coruña

UV radiation at A Coruña peaks when the sun is highest in the sky — around solar noon. At 43.4° 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 A Coruña'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 A Coruña

All solar calculations for A Coruña 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 A Coruña's coordinates (43.4°, -8.4°) — zero server processing means your location data never leaves your device.
