Weather in September
Temperature
Montejo signifies an average high-temperature of a still hot 31.8°C (89.2°F) in September, closely mirroring the 32.8°C (91°F) of August. The temperature dips to an average of 23°C (73.4°F) during September nights.Heat index
In September, the average heat index is calculated to be a life-threatening hot 45°C (113°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
Humidity
In September, the average relative humidity is 84%.Rainfall
September is the month with the most rainfall. Rain falls for 25.4 days and accumulates 140mm (5.51") of precipitation.Daylight

The months with the highest UV index are April through September, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: In September, the average maximum UV index of 7 translates into the following recommendations:
Shield from overexposure. Defense against sun-related harm is required. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
