For January, the heat index is appraised at a hot 34°C (93.2°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
