March weather forecast
Campeche, Mexico

The weather in March features an interesting blend of heat and humidity. The increasingly warm atmosphere characteristic of Campeche is evident during this month. As daylight hours jump to 12 hours, March showcases a rainfall of only 10mm (0.39"), making it one of the drier months of the year. It leaves an expectation for an even warmer April, despite possible increase in rainfall.

Temperature

The start of March sees the average high-temperature at a hot 30.8°C (87.4°F), showing little difference from February's 29°C (84.2°F). Throughout March, an average low-temperature of 21.4°C (70.5°F) is experienced.

Heat index

March's mean heat index is appraised at a very hot 36°C (96.8°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

In Campeche, the average relative humidity in March is 67%.

Note: In March, the average maximum UV index of 7 translates into the following recommendations:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Be cautious! Sand and water surfaces make the Sun's UV rays more potent.
