Weather in December
Temperature
December's onset records an average high-temperature of a still tropical 31.8°C (89.2°F), a near match to November's 33.1°C (91.6°F). Ondobe's average low-temperature is measured at a moderately hot 23.3°C (73.9°F) during December.Heat index
The heat index value during December is evaluated at a tropical 33°C (91.4°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
