April in
Doha signals the swift transition from moderate to sweltering conditions. The increasing temperatures mark the drop of the mild weather curtain, paving the way for the year's excessively hot period. The comfortable sea temperatures of around 23.7°C (74.7°F) render the city's coasts inviting for potential swimmers seeking solace from the increasing heat. With daylight prolonging to nearly 13 hours, the days start to get longer, evidencing the approach of summer. Anticipation for
May's weather should be geared towards an extreme upward curve in temperatures and a significant drop in atmospheric humidity.
Temperature
April marks a rise in the average high-temperature in Doha, moving from
March's warm 26.8°C (80.2°F) to a hot 31.9°C (89.4°F). Throughout the month of April, Doha expects an average low of 20.6°C (69.1°F).
Heat index
During April, the heat index is calculated to be a fiery hot 35°C (95°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
Humidity
In Doha, the average relative humidity in April is 52%.
Rainfall
In April, the rain falls for 1.4 days. Throughout April, 9mm (0.35") of precipitation is accumulated. Throughout the year, there are 8.8 rainfall days, and 75mm (2.95") of precipitation is accumulated.
Sea temperature
In Doha, the average seawater temperature in April is 23.7°C (74.7°F).
Note: Think about diving into 23.7°C (74.7°F) waters. Factors like your sensitivity to cold, the brightness of the sun, wind conditions, and the day's warmth play a role. For reference, Olympic swimming competitions use waters between 25°C (77°F) and 28°C (82.4°F).
Daylight
In April, the average length of the day is 12h and 46min.
On the first day of April, sunrise is at 05:24 and sunset at 17:50. On the last day of the month, sunrise is at 04:58 and sunset at 18:04 +03.
Sunshine
In April, the average sunshine is 9.1h.
UV index
April through
August, with an average maximum UV index of 12, are months with the highest UV index in Doha. A UV Index value of 11, and more, symbolizes an extreme health hazard from exposure to the Sun's UV rays for average individuals.
Note: The average daily UV index of 12 in April transforms into the following instructions:
Practice every precaution of necessity, unprotected skin and eyes might burn in minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Ensure the liberal application and reapplication of a broad-spectrum SPF 30+ sunscreen after each outdoor activity or swim, and every two hours. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
