April ushers in the first tangible signs of the torrid summer in
Sharjah. Rising temperatures characterize this month, dropping the chance of any significant rainfall drastically, as evinced by April's average rainfall of just 8mm (0.31"). The sunny weather ensures maximum visibility and longer hours of daylight, ideal for tourists aiming to experience Sharjah's beauty. It is a stark contrast from the slightly cooler, rainier
March. The consistent rise in temperature sets the stage for an exceedingly hot
May.
Temperature
Sharjah's weather shows a temperature rise with the arrival of April, moving from a warm 28.8°C (83.8°F) in March to a tropical 34°C (93.2°F). Sharjah sees a major change from daytime highs, with the nighttime temperature dipping to a comfortable 18.3°C (64.9°F) on average during April.
Heat index
The heat index value during April is estimated at a scorching 41°C (105.8°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Note: An average UV index of 12 in April transforms into this advice:
Utilize all vital precautions. Guarding against sun harm is non-negotiable. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses. Sunscreen with an SPF of 30 or higher should be applied generously and frequently reapplied even on cloudy days, especially after each swim or outdoor workout. Take note! The UV strength of the Sun elevates when reflected off water and sand.
