April weather forecast
San Sebastian, Venezuela

April, the same as March, in San Sebastian, Venezuela, is another hot spring month, with an average temperature fluctuating between 30.9°C (87.6°F) and 21.1°C (70°F).

Temperature

The transition from March to April brings an average high-temperature of a still hot 30.9°C (87.6°F), barely different from March's 32.3°C (90.1°F). Throughout April, the temperature falls to an average low of 21.1°C (70°F).

Heat index

April's heat index is calculated to be a fiery hot 36°C (96.8°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

UV index

The months with the highest UV index are February through April, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for ordinary individuals.
Note: The maximum daily UV index of 7 during April translates into the following directions:
Resist overexposure. Safeguarding from solar damage is indispensable. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
