Temperature

Playa Rancho Luna's May reports an average high-temperature of a still tropical 30.3°C (86.5°F), exhibiting a minor difference from April. During May, the nighttime temperature averages to a moderately hot 23°C (73.4°F).

Heat index

The heat index in May is computed to be a torrid 37°C (98.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

The average relative humidity in May in Playa Rancho Luna is 76%.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
