日照

Less sunshine: according to a meteorological report, sunshine hours in eastern and northern Japan during the first half of August were 30 to 50% below the yearly average, as most days were cloudy or rainy. In Tokyo, it rained on all 17 days from August 1st to 17th:

北日本や東日本の太平洋側で、8月前半の日照時間が平年の30%〜50%ほどだった。

The same word came up earlier — see the July 2019 entry, about central Tokyo's lowest average daily sunlight in 31 years.
