Weather in January
Temperature
January's presence records an average high-temperature of a still warm 28.9°C (84°F), closely mirroring December's climate. In Semampir, the average nighttime temperature during January is a still warm 23°C (73.4°F).Heat index
The heat index value for January is appraised at a fiery hot 35°C (95°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
