Weather in May
Temperature
May experiences an average high-temperature of a still warm 27.8°C (82°F), barely different from April's 28.8°C (83.8°F). Ngola encounters an average temperature dip to a still warm 25.7°C (78.3°F) throughout May, subtly lower than its daytime maximum.Heat index
In May, the heat index is appraised at a hot 32°C (89.6°F). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
