Weather in April
Temperature

In April, the heat index is computed to be a blistering 41°C (105.8°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
