One of my players is playing some kind of wind-based oracle, who can adjust existing wind speed. Therefore, I needed a mechanism to determine the current wind speed on any given day. I created the chart below using some historical wind data from an airport in Egypt, and the wind categories used in Pathfinder.
It might make significant winds a bit more common than they actually are in Egypt, but they are still pretty rare.
I post it below in the unlikely event someone else needs this obscure information...
Roll d1000.
001-774 = Light Winds
775 - 874 = Moderate Winds
875-949 = Strong Winds
950-975 = Severe Winds
976-999 = Severe winds + dust storm
1000-1024 = Windstorm + dust storm
1025 – 1027 = Windstorm + Greater Dust storm
1028-1029: Hurricane Force Winds + greater dust storm
1,030 = Tornado force winds + greater dust storm
Monthly Effects
Add 10 in March, April, May and August
Add 20 in June and July
Time Effects
Add 10 between 5-8 PM
Functionally, if your first d10 rolls a 1-6 you don't even need to reference this table, we know it is light winds.
