Weather in April
Temperature
April's onset is marked by a subtle temperature increase, moving from a warm 83.3°F (28.5°C) in March to a tropical 90.1°F (32.3°C). Despite the drastic temperature difference, Rio Grande City records an average nighttime low of 68.4°F (20.2°C) throughout April.Heat index
The heat index in April is computed to be a torrid 98.6°F (37°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
