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).

  • Sendai, Miyagi: average high 28.2 °C, 10.9 rainy days; August was 10.5% of Miyagi's year.
  • Morioka, Iwate: average high 28.4 °C, 11.2 rainy days; August was 11.3% of Iwate's year.

  • Niigata: average high 30.8 °C, 10.0 rainy days; August was 11.5% of Niigata's year.

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 Akita in August.
