Weather in July
Temperature
Halley witnesses the warmest weather in July, with temperatures averaging a high of 92.7°F (33.7°C) and a low of 72.1°F (22.3°C).Heat index
In July, the heat index is appraised at a blazing hot 113°F (45°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.The standards for the heat index are set for locations in shade and under light breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. 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 particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
Humidity
In July, the average relative humidity is 69%.Rainfall
In Halley, during July, the rain falls for 14.2 days and regularly aggregates up to 2.52" (64mm) of precipitation. Throughout the year, there are 138.1 rainfall days, and 30.71" (780mm) of precipitation is accumulated.Snowfall
May through October are months without snowfall.Daylight
In Halley, the average length of the day in July is 14h and 14min.On the first day of July, sunrise is at 6:13 am and sunset at 8:40 pm. On the last day of the month, sunrise is at 6:32 am and sunset at 8:26 pm CDT.
Sunshine
In July, the average sunshine is 10.8h.UV index
The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.Note: The daily high UV index of 7 during July translates into the following recommendations:
Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
