Golden hour and sea temperature
Evening golden hour is our calculation for the 15th of each month of 2026: the time the sun takes to go from 6° above to 4° below the horizon (there is no official definition). The sea figure is the 1991–2020 average sea surface temperature at the open-sea point nearest the weather station (NOAA OISST).

The quietest and busiest months
In 2025, February was Tokyo's quietest month (7.3% of the year's guest nights): average high 10.9 °C, average low 2.1 °C, 56 mm of rain. December was the busiest (9.1%): average high 12.0 °C, average low 3.8 °C, 58 mm of rain. The figures do not show that the weather makes a month busier or quieter, so we do not say it does.
Similar weather, quieter: ideas for December
December was Tokyo's busiest month in 2025 (9.1% of its guest nights). These places had an average high within 2 °C and rainy days within 3 of Tokyo's in December, in a different prefecture, and December took a smaller share of its 2025 guest nights than December did of Tokyo's:
- Tsu, Mie: average high 12.0 °C, 5.5 rainy days; December was 8.5% of Mie's year.
- Kobe, Hyogo: average high 12.0 °C, 5.7 rainy days; December was 8.5% of Hyogo's year.
- Hiroshima: average high 12.1 °C, 5.7 rainy days; December was 8.1% of Hiroshima's year (quieter than average).
- Okayama: average high 11.7 °C, 5.0 rainy days; December was 8.2% of Okayama's year (quieter than average).
- Tokushima: average high 12.5 °C, 5.4 rainy days; December was 7.8% of Tokushima's year (quieter than average).
Weather: 1991–2020 averages at each city's weather station (World Meteorological Organization normals in Europe, Japan Meteorological Agency in Japan); a rainy day has at least 1 mm of rain. “Quieter” compares a month with the rest of that place's own year. Try another month or place. All quieter alternatives to Tokyo in December.
What these figures are
One weather station stands for Tokyo; places nearby can differ, especially by height or distance from the sea. For the full picture of Tokyo, including regions and holidays, see our Tokyo page; for other places, the visual guides and golden hour by place.
