May weather forecast
Guanaja, Honduras

As the weather continues to warm, May marks the onset of higher humidity and rainfall with an accompanying increase in cloud coverage. This change in climate affects visibility slightly, despite it remaining relatively steady. Sea temperature continues to rise, reaching 28.3°C (82.9°F) in this month, providing excellent conditions for water-related recreational activities. A rise in temperature brings a new high of 28.6°C (83.5°F), but the increase in cloud cover and fresh winds make it bearable. Despite the increased rainfall, daylight hours, and sunshine remain fairly consistent, maintaining the balances struck in the previous month.

Heat index

In May, the average heat index is estimated at a hot 33°C (91.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Records show heat index calculations are tailored for shaded regions and mild 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 'apparent temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

Prevent overexposure. Protection from the sun's harmful effects is needed. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. Take caution! The UV rays from the Sun gain strength from sand and water reflections.
