Weather in July
Temperature
During July and August, Merlin registers its highest temperatures, averaging a high of 91.2°F (32.9°C).Heat index
The heat index value during July is appraised at a burning hot 116.6°F (47°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
Humidity
The average relative humidity in July is 78%.Rainfall
July is the month with the most rainfall. Rain falls for 19.4 days and accumulates 2.56" (65mm) of precipitation.Snowfall
In Merlin, snow does not fall in February through December.Daylight

Sunshine
In July, the average sunshine is 10.2h.UV index
The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.Note: A maximum high UV index of 7 in July translates into the following recommendations:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. 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. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
