Weather in May

May sees a more substantial rise in temperature in Road Town, indicating the onset of the warmer months. This month offers longer periods of daylight, leading to an escalation of the usual tropical heat. However, the warm clime is balanced by the increasingly cooling winds in the evening. Despite being a pre-monsoon period, rainfall increases but fails to overshadow the predominant sunny conditions. The fluctuations of temperature in May are between 26.1°C (79°F) and 27.3°C (81.1°F), signaling the beginning of the tropical summer in Road Town.

Heat index

The heat index for May is calculated to be a tropical 30°C (86°F). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. 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.
