Weather in July
Temperature
In July, the average high-temperature marginally rises from a warm 25.3°C (77.5°F) in June to a still moderately hot 29.5°C (85.1°F). In Nishiarai, the nighttime temperature averages to a still warm 23.3°C (73.9°F) during July.Heat index
In July, the average heat index is evaluated at a fiery hot 35°C (95°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

The month with the highest UV index is July, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the ordinary person.Note: The daily high UV index of 7 in July translates into this advice:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. 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.
