What time does the sun rise in ポルト today?

Today's sunrise and sunset times for ポルト are calculated using your device's location or the coordinates you enter. The times depend on ポルト's latitude (41.2°) and the current date. Solar Insight Pro uses the USNO algorithm accurate to ±1 minute. Enter ポルト as your location above and select today's date to see the exact sunrise, sunset, solar noon, golden hour, and blue hour times.

When is golden hour in ポルト?

Golden hour at ポルト occurs during the first hour after sunrise and the last hour before sunset, when the sun sits between −4° and 6° above the horizon. At ポルト's latitude (41.2°), golden hour lasts approximately 28–40 minutes. During summer months, the longer twilight at this latitude extends the golden hour window compared to equatorial locations. Open the Photography Mode tab to see countdown timers for the next golden hour and blue hour windows.

How does ポルト's latitude affect daylight hours?

ポルト at latitude 41.2° experiences significant seasonal variation in daylight. Summer days reach approximately 15.0h of daylight at the solstice, while winter days drop to approximately 15.0h — a 0.0h difference between seasons. The sun's maximum altitude ranges from 72.3° in summer to 25.4° in winter. This mid-latitude pattern is why ポルト has such pronounced seasonal changes in sunrise and sunset times compared to locations near the equator.

How accurate are sunrise times for ポルト?

Sunrise and sunset calculations for ポルト use the Jean Meeus Chapter 25 solar position algorithm, verified against the USNO Astronomical Almanac. Accuracy is ±1 minute for dates between 1901–2099. The algorithm accounts for atmospheric refraction (34 arcminutes at the horizon) and uses ポルト's precise coordinates (41.2°, -8.6°).

How Solar Calculations Work at ポルト's Latitude

Latitude & Daylight at ポルト

ポルト sits at latitude 41.2°. At this latitude, daylight varies from approximately 15.0h in summer (solstice) to 15.0h in winter — a seasonal swing of 0.0h. The sun reaches a maximum altitude of 72.3° at summer solstice and a minimum of 25.4° at winter solstice. This mid-latitude profile is what shapes ポルト's unique sunrise, sunset, and golden hour patterns year-round.

Golden Hour Photography at ポルト

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

UV Exposure & Sun Safety at ポルト

UV radiation at ポルト peaks when the sun is highest in the sky — around solar noon. At 41.2° 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 ポルト'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 ポルト

All solar calculations for ポルト 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 ポルト's coordinates (41.2°, -8.6°) — zero server processing means your location data never leaves your device.
