Goiânia, marking a transition from the rains. With only 119mm (4.69") of rainfall scattered over 8 days, it's the first significant drop in the year. Furthermore, April welcomes longer hours of sunshine, 7.6 hours in total, but slightly less daylight time than in
March - 11.7 hours. The relative humidity begins to wane, leading to cooler evenings. Anticipate a more drastic drop in humidity and rainfall levels as the next month approaches.
Temperature
The commencement of April introduces an average high-temperature of a still hot 30°C (86°F), closely mirroring the preceding month. Goiânia's temperature in April lowers to a consistent average of 18.5°C (65.3°F) during the nights.
Heat index
The heat index value for April is computed to be a sweltering 35°C (95°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. 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 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
