Abstract EN

This study aimed to analyze the temporal and spatial variation of thermal comfort levels in the Kingdom of Saudi Arabia using the Temperature Humidity Index (THI).

The study used climate data for (22) climate stations of the General Authority for Meteorology and Environmental Protection for the period from 1985-2010AD.

The study showed that there was a variation in the levels of thermal comfort between the study stations, which varies monthly and from station to another.

The study revealed that March is the best month of the year, followed by November and October, while the summer months of June, July, and August are months of the year with climate and thermal discomfort because of the high temperatures in most of the stations.

The study showed that the mountain station of Abha is the best station for the study of thermal comfort, followed by the stations of Ta’if and Al-Bahah.

Jazan coastal station is the highest stations under thermal stress due to the high temperature and relative humidity, followed by the Makkah Al-Mukarramah and Dhahran stations.
