Its actually just as easy to get dehydrated (maybe even more so ) in extreme cold weather.
Cold Weather Increases Risk Of Dehydration
I have never seen data to suggest that DVT's are more prevalent in either extreme hot or cold climates.
The "classic" risk factors for clot formation are encompassed by Virchow's Triad which include stasis (slowing of blood flow), vascular wall injury and hypercoagulable states.

Dehydration probably does influence clot formation although there has only been one or two studies looking directly at this phenomenon.
Just because someone lives in a hotter climate does not necessarily correlate with dehydration any more than living in a cold climate.
There is no data to suggest people are suffering DVT's at a higher rate in warmer climes than more temperate climes.
This table shows that DVT incidence pretty well mirrors population trends not climate
