My friend I see potential in your willingness to learn about the ancient Arab and Semitic world. But let me tell you this. There is snow in KSA too. The Arab world and KSA is very diverse. Also in terms of micro-climates. The mountainous parts of Hijaz (large parts of the region are mountainous) have even a very pleasant climate. Even summers in Hijaz and KSA are very pleasant if you like warmth which many people do. Personally I can't stand cold climates· Tai'f in Hijaz, lcoated 2000 meters above sea level, has a very nice climate all yaer long and snowfall in the winter. Even Jeddah along the beautiful tropical Red Sea always have mild winds that blow.
Punjab btw has a similar climate. Lahore is warmer than Sana'a for example. Much warmer. It depends where you go in the Arab world. But sure most of the climate is warm which is good. Or do you prefer Siberia?
Anyway you should visit the Arab world. It is a must to understand us as a people since you seem very interested. Met normal people from all segments, backgrounds. People are very hospitable. Arabian hospitality is world famous. People will invite you home. Go to Yemen and met poor people there. Go to Egypt do the same. Go to Qatar to see the differences and contradictions. Go to Libya etc. So much to see. Unfortunately a unstable region.
Anyway as I said you are welcome to visit Hijaz and I can show you around. I would like to met persons from this forum, LOL to see how they are in real life. I have grown up in Makkah and pilgrims from all over the world has been part of my upbringing and life in some extent. I have met old Western crippled pilgrims and devout Somalians all with the same goal - performing hajj.
