Weather in May
Temperature
The transition from April to May brings a subtle temperature rise, with average high-temperatures increasing from 77.7°F (25.4°C) to a still warm 83.8°F (28.8°C). In Sweeny, the May nights cool down to an average low of 69.6°F (20.9°C).Heat index
For May, the heat index is computed to be a tropical 93.2°F (34°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
