Temperature

The shift from April to May introduces a subtle increase in the average high-temperature, moving from 30.8°C (87.4°F) to a still tropical 34°C (93.2°F). Throughout May, Gio Nhan's nights cool down to an average of 24.8°C (76.6°F).

Heat index

For May, the heat index is estimated at a blazing hot 49°C (120.2°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Understanding the heat index involves considering values for shaded locales with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

In May, the average relative humidity is 74%.
