We don't know *where* you're hearing all this from--but it sounds like you need better resources.
Waikaloa has had some vog here and there-true. Is it constant and horrible-no.
The Kailua Kona and southern points do have some very bad vog.Edited: 22 May 2018, 19:15
I read it on a TA post earlier today. Travelers from CA cut their vacation short and said Kona airport is “bedlam” because others are trying to leave too. They posted that the air quality got better on May 17th and then worse on the 20th due to change in trade winds.
Well, you need to consider the source, as I mentioned. One person's panicked reaction and being at the airport when there are a bunch of flights leaving--not bedlam, just busy.
You can look at webcams and even check flight arrivals and departures. You can read more than the one OMG I AM GOING TO DIE I HAD TO LEAVE posts, or not.
Shea, KK, and many of us have tried very hard to present and offer reliable info and sources. I encourage you to read more critically and more of the current info threads.
KOA is normally very busy. Flights arrive and depart full.
Air quality is great today in Waikoloa Beach Resort. It's bright sunny skies. The weather and air are the best they've been in months. There were a couple of days last week that were voggy, but that's it. Here's a website that I've posted before that shows the wind patterns and levels of sulfur dioxide and other chemicals in the air. You can drag the screen to show the levels in other parts of the world. The air is likely much better here than where you live. https:/…42.119
