September weather forecast
Río Alejandro, Panama

Entering September, the atmospheric shift in Río Alejandro has hints of the drying period approaching days. Despite September being within the monsoon season, the city experiences reductions in average rainfall and relative humidity. The leisurely winds coupled with the decline in number of sunniest days are characteristic of the slowly changing climate. The wind speed further decreases to 7.3km/h (4.5mph) from 7.8km/h (4.8mph) in August, suggesting calmer afternoons. A subtle transformation ensues, paving the path for alluring climatic novelties in the upcoming months.

Temperature

The commencement of September records an average high-temperature of a still warm 28.7°C (83.7°F), barely varying from August's 28.5°C (83.3°F). Río Alejandro, during September nights, experiences a subtle shift to a low average of 25.1°C (77.2°F) from the day's heat.

Heat index

For most parts of September, the heat index is evaluated at a torrid 35°C (95°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
