May, the last month of the spring in Atlantis, is also a moderately hot month, with temperature in the range of an average high of 81.3°F (27.4°C) and an average low of 75.7°F (24.3°C).

Temperature

May's onset brings an average high-temperature of a still moderately hot 81.3°F (27.4°C), showing a minute difference from April's 79.2°F (26.2°C). A slight dip in temperature to a still warm 75.7°F (24.3°C) marks the average nights in Atlantis during May.

Heat index

The heat index value during May is calculated to be a hot 86°F (30°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
