Weather in May
Temperature
May commences with an average high-temperature of a still moderately hot 81.9°F (27.7°C), showing little deviation from April's 78.4°F (25.8°C). Maintaining close parity with daytime warmth, the average nocturnal temperature during May stays at a pleasant 73°F (22.8°C).Heat index
May's average heat index is evaluated at a tropical 87.8°F (31°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Factoring in the heat index, values are geared towards shaded areas with light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
