Weather in July
Temperature
In West Salem, the highest average temperatures are observed in July, with a high of 84.7°F (29.3°C) and a low of 67.6°F (19.8°C).Heat index
In July, the heat index is evaluated at a very hot 96.8°F (36°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
