May brings about a significant change in
Al-Qayrawan's weather, marking the transition towards a summer climate. As the amount of daylight further expands, the city becomes brighter and livelier. The decreasing humidity, coupled with a significant reduction in rainfall, signifies the beginning of the drier season. By now, the days have warmed considerably, with temperatures reaching up to 28.3°C (82.9°F) by the month end. Outdoor activities remain pleasant, however, the midday sun may start to feel sturdy.
Temperature
May's onset in Al-Qayrawan,
Tunisia, brings a rise in the average high-temperature, moving from a warm 23.3°C (73.9°F) in
April to a still moderately hot 28.3°C (82.9°F). Al-Qayrawan's May nights see a large temperature deviation, with temperatures resting at a low of 14.1°C (57.4°F).
Heat index
May's mean heat index is appraised at a tropical 30°C (86°F). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
