Weather in May
Temperature
May's commencement is accompanied by an average high-temperature of a still tropical 33.1°C (91.6°F), diverging marginally from April's 33.3°C (91.9°F). In the month of May, Astillero's average low-temperature falls to a warm 26.4°C (79.5°F).Heat index
May's average heat index is appraised at a scorching 43°C (109.4°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
