I'm planning to visit Luang Prabang in early March, but am a bit concerned by reports of smoky air during this period. These reports are very mixed, however, with some travelers not bothered by it at all. I know this topic has been asked about in the past, but not since 2009, so I am wondering if anyone knows how the smoke factor was last March. The alternative plan is to travel longer in Vietnam and try to get to Luang Prabang in a better season in the future. Sorry to ask, but any advice?
