May weather forecast
Nam Tau, Cambodia

Weather in May witnesses significant changes, with temperatures fluctuating between 26.5°C (79.7°F) and 34.5°C (94.1°F), and rainfall registering a peak at 110mm (4.33"), spread over 23.2 days. The increased rainfall and subsequent rise in relative humidity to 71%, highlight the heavy monsoon month. As the cloud cover thickens, the intensity of sunshine hours decreases to 10.3 hours daily; however, it's still relatively high given the extent of rainfall. With an average wind speed of 6.7km/h (4.2mph), Nam Tau continues to experience mild breezes amidst the vibrant, tropical vegetation. Outdoor enthusiasts should be prepared for potential rain-related disruptions and remember to carry suitable rain gear.

Temperature

With the transition into May, Nam Tau notes an average high-temperature of a tropical 34.5°C (94.1°F), closely resembling April. Nam Tau, during the nights of May, experiences an average temperature drop to a moderately hot 26.5°C (79.7°F).

Heat index

The heat index in May is estimated at a life-threatening hot 49°C (120.2°F). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. 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. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Humidity

In May, the average relative humidity is 71%.

Rainfall

In May, the rain falls for 23.2 days. Throughout May, 110mm (4.33") of precipitation is accumulated. In Nam Tau, during the entire year, the rain falls for 224.1 days and collects up to 1267mm (49.88") of precipitation.

On the first day of May, sunrise is at 05:44 and sunset at 18:22. On the last day of the month, sunrise is at 05:37 and sunset at 18:30 +07.

Sunshine

In Nam Tau, the average sunshine in May is 10.3h.

UV index

In May, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for ordinary individuals.
Note: In May, the maximum UV index of 7 suggests this advice:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
