You must defeat the 4th Gym Leader in Lavaridge Town, when you come out of the gym, May, (Or if your playing as a girl, Brenden), will come out of the building to the right, and walk over to you, they will then give you the Sand Goggles, and it will allow you to go through the sandstorm into the desert.
Hope this helped :)

There is a constant sandstorm on route 228 on Pokemon Diamond. It is not possible to ever remove this sandstorm.
to get past the wailmer go to mt. pyre (if not already done) then goto mt. chimney
