Weather in January
Temperature
January's climate shows a minor adjustment in average high-temperatures to a still moderately hot 28.5°C (83.3°F) from December's 28.3°C (82.9°F). The nights of January cool down to an average low of 27.6°C (81.7°F), subtly lower than daytime highs.Heat index
During January, the heat index is calculated to be a hot 33°C (91.4°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
