Weather in April

April sees Campeche transitioning steadily into its hottest month. The increase in temperature and humidity makes the heat of the Mexican city quite palpable. Watch out for the highest relative humidity of the year 66%, as the temperature can rise high. April ushers in the anticipation of the looming wet season with increased rainfall, which fully arrives in coming months.

Temperature

The transition from March to April brings an average high-temperature of a still hot 33°C (91.4°F), barely different from March's 30.8°C (87.4°F). Throughout April, Campeche experiences a low-temperature average of 23.6°C (74.5°F).

Heat index

In April, the average heat index is computed to be a scorching 42°C (107.6°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The least humid month is April, with an average relative humidity of 66%.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Attention! The combination of sand and water reflections enhances UV ray intensity.
