Weather in February
Temperature
Dumai observes an average high-temperature of a still tropical 31.5°C (88.7°F) in February, barely different from 30.6°C (87.1°F) in January. In Dumai, the expected average low-temperature for February is a warm 23.9°C (75°F).Heat index
In February, the average heat index is calculated to be an extremely hot 42°C (107.6°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

The month with the least rainfall in Dumai is February, when the rain falls for 18.7 days and typically collects 52mm (2.05") of precipitation.Sea temperature

The months with the highest UV index are January through September and November, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV rays for the ordinary person.Note: In February, the maximum UV index of 7 suggests this advice:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Watch out! Reflections from sand and water can surge UV radiation exposure.
