Weather in April
Temperature
April tends to be the warmest month, with temperatures averaging a daily high of 29.6°C (85.3°F) and a low of 22.8°C (73°F).Heat index
April's average heat index is appraised at a hot 33°C (91.4°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Observations indicate that the heat index values are for shady locations with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
