, the first month of the rainy (monsoon) season in Mumbai
, is still a hot month, with temperature in the range of an average low of 26°C (78.8°F) and an average high of 32.1°C (89.8°F).
In June, the average high-temperature is almost the same as in May
- a still hot 32.1°C (89.8°F). In Mumbai, in June, the average low-temperature is 26°C (78.8°F).
The average heat index in June is estimated at an extremely hot 44.7°C (112.5°F). Beware
: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'felt air temperature', 'real feel', 'feels like', or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like activity, metabolic differences, clothing, and wind affect individual temperature impact. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.
In June, the average relative humidity is 80%.
In Mumbai, during 14.5 rainfall days, 523.1mm (20.59") of precipitation is typically accumulated. Throughout the year, there are 78.9 rainfall days, and 2258mm (88.9") of precipitation is accumulated.
June is the month with the warmest seawater, with an average sea temperature of 30°C (86°F).Note
: The surface water temperatures above 30°C (86°F) are arguably considered as unpleasant for swimming, and any intense water activity, as the refreshing effect of water is missing.
With an average of 13h and 16min of daylight, June has the longest days of the year in Mumbai.
On the first day of the month, sunrise is at 6:00 am and sunset at 7:12 pm. On the last day of June, in Mumbai, sunrise is at 6:04 am and sunset at 7:20 pm IST.
The average sunshine in June is 5h.
, with an average maximum UV index of 12, are months with the highest UV index. A UV Index reading of 11, and higher, represents an extreme health hazard from unsafe exposure to UV radiation for average individuals.Note
: The daily maximum UV index of 12 in June interpret into the following advice:
Take all necessary precautions, as unprotected skin can burn in minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
