In Lampang, September's average high-temperature stands at a still hot 32.8°C (91°F), closely related to the preceding month. Lampang encounters a steady low-temperature average of 23.5°C (74.3°F) throughout the month of September.

Heat index

The heat index in September is calculated to be a blazing hot 49°C (120.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
