Increasing trends were observed in case of annual total cooling degree-days (CDD) and industrial degree-days over the period of study at all base temperatures. Furthermore, well-defined seasonal trends were seen with increasing values from January to July and then decreasing towards the end of the year. The heating degree-days (HDD) analysis indicated slight heating during January to March and in December. The annual total HDD showed decreasing trends at both base temperatures. It is worth mentioning that the rate of increase of annual CDD was found to be decreasing with decreasing latitude on the Red Sea coast from Al-Wejh to Gizan with an exception at Yanbo, where it was higher than at Al-Wejh. On the other hand, the rate of decrease of annual HDD was found to be decreasing with decreasing latitude on the Red Sea coast from Al-Wejh to Gizan. The seasonal and annual values of cooling degree-days were found to be comparable with corresponding values for stations like international airports in Kuwait, Bahrain, Qatar, Musqat, and Cairo with similar types of climatic conditions.
