Weather in May
Temperature
The advent of May signifies a minor shift to an average high-temperature of a still warm 28.8°C (83.8°F), aligning closely with April. A mild drop to an average of 25.3°C (77.5°F) marks the nights during May.Heat index
The heat index in May is estimated at a tropical 34°C (93.2°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Remember that heat index calculations are made for conditions in the shade with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
