Weather in January
Temperature
The initiation of January records an average high-temperature of a warm 29.4°C (84.9°F), displaying a near consistency with the previous month. A slight dip in temperature to a still moderately hot 25.3°C (77.5°F) marks the average nights during January.Heat index
For most parts of January, the heat index is calculated to be a torrid 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
