Question: Does vog reach every main island in the State of Hawaii?vog-01

Answer: Yes. Although volcanic emissions from the Kilauea volcano (located on the Big Island) and wind patterns are unpredictable, I can provide a basic understanding of how each of Hawaii's main islands are affected by that substance:

Vog is common in these locations:

  • Big Island - West

Vog is uncommon in these locations:

  • Big Island - East
  • Lanai
  • Mauai
  • Molokai
  • Oahu

Vog rarely reaches these locations:

  • Kauai
  • Niihau

Vog is uncommon or rare in those locations because Hawaii's normal northeast trade winds either blows Kilauea's vog out to sea, and/or to the western part of the Big Island, but abnormal prolonged periods of southerly winds can blow that substance to the rest of the island chain.
