理解する "Feels Like" Temperature
Weather apps often show a "feels like" or "apparent" temperature that differs from the actual temperature. This accounts for:
- Wind Chill: Wind makes cold temperatures feel colder by stripping heat from your body faster
- Heat Index: Humidity makes hot temperatures feel hotter because sweat doesn't evaporate as efficiently
Example: An actual temperature of 30°C (86°F) with high humidity might have a "feels like" of 38°C (100°F).
