Hingis set to take court for first time in two years
But the Swiss star said the tropical temperature in Thailand was "a shock to my body because back in Switzerland the temperature is minus 10."
Leading the field of entrants in Pattaya is world No. 11 ranked Vera Zvonareva of Russia. Seeded second to fourth are Marion Bartoli of France, Conchita Martinez of Spain, and American Mashona Washington.
The 20-year-old Zvonareva is pitted against Argentina's Maria Emilia Salerni in the first round, while Bartoli has a comfortable opening match against wild card Ayu Fanti Damayanti of Indonesia. Veteran Martinez will play a qualifier while Washington will encounter Ukraine's Alyona Bondarenko.
Jelena Dokic, the former No. 4 ranked player who slipped to 126 this week, also joins the action and will play Anne Kremer of Luxembourg in the first round.
Hingis beat Weingartner in 1999 and 2002.
