Weather in June
Temperature
The shift into June records an average high-temperature of a still hot 31°C (87.8°F), subtly varied from May's 31.8°C (89.2°F). The average low-temperature, in June, is a pleasant 22.8°C (73°F).Heat index
For most parts of June, the heat index is evaluated at a fiery hot 39°C (102.2°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
Humidity
The average relative humidity in June is 74%.Rainfall
June is the month with the least rainfall. Rain falls for 14.7 days and accumulates 29mm (1.14") of precipitation.Daylight
With an average of 12h and 36min of daylight, June has the longest days of the year.On the first day of June, sunrise is at 05:50 and sunset at 18:22. On the last day of the month, sunrise is at 05:55 and sunset at 18:29 +0530.
Sunshine
The month with the most sunshine is June, with an average of 11h of sunshine.UV index
The months with the highest UV index are March through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for ordinary individuals.Note: An average maximum UV index of 7 in June leads to these recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
