The rainy season (25°C, 90%) has a gap of 1.3°C and is slower still. In the sun, solar radiation warms the fabric, so this calculation no longer holds and summer can catch up. Wind replaces the moist air at the surface and can change the speed several-fold. The most water vapour air can hold just under doubles (1.7–2 times) for every 10°C rise.

|本文=How fast laundry dries depends not on the temperature or the humidity alone but on the gap between the two thermometers of a psychrometer (the difference from the wet-bulb temperature). In the shade or indoors, a dry, clear winter day (5°C, 40% humidity, a gap of 4.4°C) dries laundry faster than a muggy summer day (30°C, 80% humidity, a gap of 2.9°C).
|なぜ=Wet fabric loses heat as its water evaporates and cools to the wet-bulb temperature, below the air temperature. The drying force is the difference in water vapour between this cooled surface and the air, so even when it is hot, the difference is small if the humidity is high.
|ジャンル=生活・家事
|ファクト度=A
|ファクト度の根拠=The principle that a drying object stays at the wet-bulb temperature was confirmed in university lecture notes (secondary), and the figures were calculated with the psychrometer formula. No measurements comparing laundry drying across seasons were found, so not rated S
|ネタ度=S
|ネタ度の根拠=Shows with numbers that the intuition "laundry dries faster in summer" is reversed in the shade
|便利度=A
|便利度の根拠=Useful when choosing the day or place to hang laundry, and for putting air flow on laundry dried indoors
|検証ステータス=根拠あり
|根拠1URL=https://mail.rpaulsingh.com/lectures/drying_time.pdf
|根拠1要約=Lecture notes by Professor R. Paul Singh (food engineering, UC Davis). During the constant-rate drying period, the product temperature stays at the wet-bulb temperature of the surrounding air

|根拠2要約=Lecture notes from RGPV, a state technical university in India. When radiant heat reaches the drying object, its temperature rises above the wet-bulb temperature (why sun-drying falls outside the calculation)

|根拠3URL=https://www.jma.go.jp/jma/kids/kids/faq/a5_25.html
|根拠3要約=FAQ for children by the Japan Meteorological Agency. The laundry index seems to be calculated from temperature, humidity, wind speed, solar radiation and so on; it is calculated by private weather companies, not the agency, so the formula is not published
