Weather in May

May's onset brings a subtle temperature rise, moving from 25°C (77°F) in April to a still warm 28.4°C (83.1°F). The temperature during May nights demonstrates a small drop from the daytime highs, settling to an average of 24.8°C (76.6°F).Heat index
Throughout May, the heat index is calculated to be a hot 34°C (93.2°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating.
