November initiates the departure from the monsoon season, with reduced rainfall and humidity levels. The plummet in rainfall averages to 51mm (2.01"), trending towards the drier season. Despite the seasonal shift, the temperature remains consistently warm as daylight hours slightly decrease. The transition fosters inviting sea conditions for enthusiasts.
Temperature
In November,
Rayong experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 32.3°C (90.1°F) in
October to a still tropical 32.6°C (90.7°F). Nighttime temperature lowers to an average of 23.3°C (73.9°F) in November.
Heat index
The heat index value for November is estimated at a blistering 44°C (111.2°F).
Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
In terms of the heat index, values are set with light wind and shade conditions in mind. 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 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
Humidity
The average relative humidity in November is 74%.
