Weather in May
Temperature
May introduces a minor temperature shift, with average high-temperatures adjusting from April's 76.8°F (24.9°C) to a still warm 82.8°F (28.2°C). Throughout the month of May, Fernandina Beach observes an average nighttime temperature of 69.4°F (20.8°C).Heat index
The heat index for May is evaluated at a tropical 87.8°F (31°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
