What time does the sun rise in レイキャビク today?

Today's sunrise and sunset times for レイキャビク are calculated using your device's location or the coordinates you enter. The times depend on レイキャビク's latitude (64.1°) and the current date. Solar Insight Pro uses the USNO algorithm accurate to ±1 minute. Enter レイキャビク 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 レイキャビク?

Golden hour at レイキャビク 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 レイキャビク's latitude (64.1°), golden hour lasts approximately 60–90+ 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 レイキャビク's latitude affect daylight hours?

レイキャビク at latitude 64.1° experiences significant seasonal variation in daylight. Summer days reach approximately 20.5h of daylight at the solstice, while winter days drop to approximately 20.5h — a 0.0h difference between seasons. The sun's maximum altitude ranges from 49.3° in summer to 2.4° in winter. This polar pattern is why レイキャビク has such pronounced seasonal changes in sunrise and sunset times compared to locations near the equator.

How accurate are sunrise times for レイキャビク?

Sunrise and sunset calculations for レイキャビク 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 レイキャビク's precise coordinates (64.1°, -21.9°).

How Solar Calculations Work at レイキャビク's Latitude

Latitude & Daylight at レイキャビク

レイキャビク sits at latitude 64.1°. At this latitude, daylight varies from approximately 20.5h in summer (solstice) to 20.5h in winter — a seasonal swing of 0.0h. The sun reaches a maximum altitude of 49.3° at summer solstice and a minimum of 2.4° at winter solstice. This polar profile is what shapes レイキャビク's unique sunrise, sunset, and golden hour patterns year-round.

レイキャビクは2026年8月12日の皆既日食の皆既帯の真っ只中に位置します——中心線上にあるわずか2つの首都（グリーンランドのヌークと共に）の一つです。北緯64.1度では、この都市の極端な季節的薄明により、食の太陽はUTC約17:30に低く空に懸かり、アイスランドの火山景観を背景に永遠の夏の黄昏の中で日食を撮影する貴重な機会となります。

Golden Hour Photography at レイキャビク

Golden hour at レイキャビク occurs when the sun sits between −4° and 6° above the horizon, producing soft, warm, directional light ideal for portrait and landscape photography. At レイキャビク's latitude, morning golden hour typically starts in the hours after sunrise (when sun rises) and lasts approximately 60–90+ 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.

北緯64.1度のレイキャビクは世界最北の首都であり、5月下旬から8月上旬まで白夜を経験し、6月の夏至前後には市民薄明が一晩中続きます。この極端な緯度は、地球上で最も長い夏のゴールデンアワーを生み出します——太陽が完全に沈むことなく地平線をかすめる中、最大3時間にわたる柔らかな琥珀色の光が続きます。

UV Exposure & Sun Safety at レイキャビク

UV radiation at レイキャビク peaks when the sun is highest in the sky — around solar noon. At 64.1° latitude, peak UV levels vary significantly by season: summer months see UV indices of 2–4 (low-moderate), while winter months typically register 0 (none). The World Health Organization recommends sun protection when UV index exceeds 3. At レイキャビク's latitude, this threshold is exceeded for approximately 2–4 months per year, making sun awareness a year-round consideration for outdoor workers and athletes.

How We Calculate Solar Data for レイキャビク

All solar calculations for レイキャビク 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 レイキャビク's coordinates (64.1°, -21.9°) — zero server processing means your location data never leaves your device.
