Diu's temperatures peak on average in May, reaching 36°C (96.8°F) at their highest and 27.5°C (81.5°F) at their lowest.

Heat index

The average heat index in May is computed to be a life-threatening hot 48°C (118.4°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Note: An average maximum UV index of 8 in May leads to these recommendations:
Always be careful, as unprotected skin and eyes might burn in no time. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Always opt for UVA and UVB-resistant sunglasses on radiant days. Notice! Sand and water reflections contribute to a stronger UV exposure.
