Yes: Hot weather results in vasodilation of veins, and one can see more swelling. Check your compression hose which often lasts about 3-4 months, and if they are easy to put on, it's probably time to get new ones.

Yes: Not unusual with increased arterial blood flow and some venous obstruction producing edema . The Coumadin (warfarin) does not affect edema just reduces clotting progression.

Leg swelling: After a DVT can certainly be worse in hot weather, as drs. Wright and isobe said. A very common cause of swelling after a DVT is post thrombotic syndrome. This is improved by wearing 30-40 mm hg knee graduated compression stockings daily for two years after your dvt.
Dr. Norman Chideckel

Dvt: Yes is not uncommon for increased humidity to increase swelling of a lower extremity. I would recommend that she place the compression stocking on the leg prior to the leg being dependent to obtain the maximum benefit. This is assuming that the leg swelling is improved with leg elevation.
