Weather in April
Temperature
During April, London observes a subtle ascent to a still moderately hot 27.4°C (81.3°F) from March's 27°C (80.6°F) in the average high-temperature. London experiences a minimal drop from daytime high temperatures, recording an average low-temperature of 26.2°C (79.2°F) throughout April.Heat index
In April, the heat index is computed to be a hot 31°C (87.8°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.

Shield from overexposure. Defense against sun-related harm is required.
