October marks the beginning of a transitional period in
Phitsanulok's weather landscape. While there is still significant rainfall at 163mm (6.42"), it is distinctly less than that recorded in the previous month. This reduction in precipitation accompanied by steady temperature ranges symbolize the drawdown of the monsoon season. Slight changes in the length of daylight hours further hint at the impending season change. The city starts to dry out gradually, preparing for the upcoming dry months.

Phitsanulok's October average high-temperature settles at a still hot 32.4°C (90.3°F), showing a near match with the preceding month. In October, the nighttime temperature lowers to an average of 24.1°C (75.4°F).
Heat index
The heat index for October is evaluated at a burning hot 45°C (113°F).
Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
