Tama kayo it's the climate causing it....(this is how the lightning is formed ....its one huge static charge)...why don't you ground yourself...try holding a metal post or water pipe na nakaconnect sa ground.....but don't just touch it lightly kasi tatalon lang ang kuryente na pa rang lang what you're experiencing na....you should grab it....the static charge will "drain".....try searching also a popular science site, ang alam ko me solution na dyan (clothes na ang fabric can "resist" static electricity charging)

my 2 cents.
