Weather in January
Temperature
January is Wonocolo's coldest month, registering average high temperatures of 29.9°C (85.8°F) and lows of 23.3°C (73.9°F).Heat index
The heat index in January is calculated to be a sweltering 39°C (102.2°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. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
