In April, Dumara experiences a minor shift in meteorological conditions with average high-temperatures marked at a still tropical 30.3°C (86.5°F), closely mirroring the climate in March. April in Dumara sees the temperature falling to a mean low of 22.9°C (73.2°F).

Heat index

The average heat index in April is evaluated at an extremely hot 40°C (104°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
