Weather in April
Temperature
Apalen's warmest month, April, registers temperatures that range from a high of 34.9°C (94.8°F) to a low of 23.4°C (74.1°F).Heat index
In April, the heat index is appraised at a life-threatening hot 48°C (118.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.The metrics for the heat index are tailored for both shady environments and light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 quite important for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
