Weather in May
Temperature
A minor adjustment in Astillero's average high-temperature is noted with the start of May, touching a still hot 33.1°C (91.6°F) from April's 33.3°C (91.9°F). Throughout May, the temperature tends to fall to a consistent average low of 26.4°C (79.5°F).Heat index
Throughout May, the heat index is appraised at an extremely hot 43°C (109.4°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
