Weather in January
Temperature
A slight uplift of average high-temperatures is noted in January, with temperatures adjusting from a warm 28.9°C (84°F) in December to a tropical 32°C (89.6°F). Despite a significant deviation from daily highs, January sees an average nighttime temperature of 18.8°C (65.8°F).Heat index
January's heat index is appraised at a hot 34°C (93.2°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. 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. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
