Weather in March
March sees a slight decline in temperatures and rainfall in comparison to February. As the month progresses, there is a gradual transition from the intense tropical monsoon climate towards a milder climate. The residual monsoonal influence continues to provide substantial rain, although the intensity decreases. The efficacy of air conditioning increases with a noticeable decrease in humidity towards the later part of the month. The climate sets the backdrop for dazzling sunsets over the ocean and the Great Barrier Reef.Temperature

During March, the heat index is calculated to be a tropical 33°C (91.4°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
