June weather forecast
Kemah, TX

June, the first month of the summer in Kemah, is a tropical month, with temperature in the range of an average high of 88°F (31.1°C) and an average low of 78.1°F (25.6°C).

Temperature

June's arrival brings a modest temperature shift, moving from a warm 82.2°F (27.9°C) in May to a tropical 88°F (31.1°C). In June, Kemah reports a consistent average low-temperature of 78.1°F (25.6°C) during the nights.

Heat index

In June, the average heat index is calculated to be a very hot 102.2°F (39°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in June is 75%.

UV index

The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for the average person.
Note: The daily high UV index of 7 in June translates into this advice:
Shun overexposure. Protection from sun ravages is indispensable. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Be alert! The reflection of water and sand augments UV radiation intensity.
