I am from Swakopmund on the West coast. The dz is about 5 km from town and busy 7 days a week.
Tsumeb isn't really the place to go because it only operates once in about 2 months, so you wouldn't be able to skydive whenever.
You should take my email adress and let me know when you want to come.
Lots of cool stuff to do here in Swakopmund, it's like the adventure capital of the world.
Let me know.
