Weather in March
Temperature
Observing a slight rise in March, the average high-temperature shifts from February's moderately hot 75.4°F (24.1°C) to a still warm 82°F (27.8°C). In the month of March, McAllen records a consistent average low-temperature of 63.1°F (17.3°C).Heat index
In March, the heat index is evaluated at a hot 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
