Weather in June
Temperature
In June, the average high-temperature increases from a moderately hot 76.5°F (24.7°C) in May to a hot 86.9°F (30.5°C). During the month of June, the temperature in Grayson falls to an average of 69.4°F (20.8°C).Heat index
For most parts of June, the heat index is computed to be a fiery hot 100.4°F (38°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. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Ward off overexposure. Defence against solar harm is crucial. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
