How Long Is Golden Hour? We Measured It for 27 Cities

This was originally published on the LK Forge blog, where the charts are interactive and every city links to its live local time.

Golden hour is almost never an hour. Photo apps and calendars round it to a flat 60 minutes, but that number isn't measured — it's a convenience. Using the NOAA solar-position algorithm, we computed the real duration — sun between +6° and the horizon, evening — for 27 cities across three dates in 2026. It's shorter than advertised almost everywhere, and it never reaches an hour.

The numbers

The 60-minute golden hour is a myth. At the March equinox not one of these 27 cities reaches 45 minutes — the average is about 30.2 minutes.

Golden hour gets longer as you leave the equator

Sorted by absolute latitude, the equinox golden hour lengthens almost monotonically from the equator to the highest-latitude city in the set — Singapore at 24 minutes up to Berlin at 39.6 minutes.

Shortest at the equinox, longest in winter — and the swing grows with latitude

Near the equator the swing is barely there: Singapore moves from about 24 minutes at the equinox to 26 at either solstice, under three minutes across the whole year. London, at 51.5°N, swings much further — about 39 minutes at the equinox stretching to roughly 55 minutes at the December solstice. Sydney sits in the southern hemisphere, so its calendar flips: golden hour peaks at Sydney's own winter solstice in June (about 34 minutes), not in December. The pattern holds throughout this dataset — higher latitude means a bigger seasonal swing.

Why latitude decides golden-hour length

Near the equator the sun drops toward the horizon almost vertically, so it crosses the +6°→0° elevation band quickly — golden hour in Singapore lasts about 24 minutes at the equinox and barely moves across the year. Toward the poles the sun descends at a shallower angle, so the same band takes longer to cross. London's equinox golden hour runs about 39 minutes, stretching to roughly 55 minutes at the December solstice; Berlin, at a similar latitude, peaks near 58 minutes in December — the longest in this dataset.

The low winter sun is why the winter solstice produces the longest golden hour of the year in this dataset, not midsummer — a small margin near the equator, where the seasonal swing is barely a minute, but a gap of several minutes at higher latitudes, like London's roughly 55 minutes in December against 47 in June. Even so, every city here — up to Berlin's 52.5°N — stays under an hour. Golden hours that genuinely exceed 60 minutes need latitudes above roughly 60°N, places like Reykjavík or Anchorage, beyond the reach of this 27-city set.

Reproduce it yourself

The harness is deterministic and public. It's one script — the NOAA low-precision solar-position algorithm — run against the same 27 cities and three dates (March equinox, June & December solstices, 2026), printing golden hour as the time the sun spends between +6° elevation and the horizon, evening.
