Weather in September
Temperature
Fundación starts September with an average high-temperature of a still tropical 32.1°C (89.8°F), hinting at a minimal fluctuation from August. September is noted for a mean low-temperature of 21.5°C (70.7°F).Heat index
The heat index value during September is estimated at a blistering 41°C (105.8°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
