The first month of the summer, June, is a hot month in Houston, Texas, with average temperature fluctuating between 91°F (32.8°C) and 75.4°F (24.1°C).

Temperature

In June, the average high-temperature is essentially the same as in May - a tropical 91°F (32.8°C). The average low-temperature, in June, is 75.4°F (24.1°C).

Heat index

In June, the average heat index is appraised at a blistering 111.4°F (44.1°C). Beware - heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel', 'felt air temperature', 'apparent temperature', or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional factors like activity, clothing, metabolic differences, and differences in body mass, height, and shape affect individual temperature impact. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 99.5°F (37.5°C) to 100.9°F (38.3°C), thermal conditions are potentially life-threatening.

Humidity

The average relative humidity is 73%.

Rainfall

In Houston, it is raining for 17.2 days, with typically 3.27" (83mm) of accumulated precipitation. In Houston, during the entire year, the rain falls for 180.5 days and collects up to 35.35" (898mm) of precipitation.

Snowfall

February through November are months without snowfall.

Daylight

June has the longest days of the year, with an average of 14h of daylight.

Sunshine

In June, the average sunshine is 10.4h.

UV index

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from the exposure to the Sun's UV rays for average individuals.
Note: In June, the average maximum UV index of 7 translate into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. 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. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun.
