Pretty concerned about recent Vog on Kona side Big Island

Question

I'm scheduled to stay on the big island later this week, and I have health issues and won't do well in the vog. I'm heartbroken to see that it has been all along Kona side to Kohala coast. Purple air shows me it's a little better than yesterday, but what should I do as a backup plan if it picks up again? Try to go to another island last minute? I'm going to Hawaii to be outside and take in the ocean air. Thanks for any suggestions!

Answer

I completely understand your concern — vog (volcanic smog) on the Kona side can be a real challenge, especially for anyone with respiratory or heart issues. The situation can change quickly depending on wind direction, but there are some practical steps and backup plans you can consider to protect your health and still enjoy your trip.

Monitoring & Immediate Precautions

Keep an eye on real-time air quality maps such as PurpleAir and Hawaii’s vog information sites. They give hour-by-hour updates of particulate matter and sulfur dioxide levels.
If the vog is high, try to stay indoors in places with filtered air (your hotel or rental with AC and air purifiers). Avoid outdoor activities in affected areas until the air clears.
Carry masks rated for fine particulates (like N95 or KN95), which can help reduce exposure when outside.
Check local forecasts — the wind can shift the vog, sometimes within hours, so mornings may be clearer than afternoons.

Alternative Activities / Locations on the Big Island

Consider spending more time on the eastern side (Hilo side) of the island. The trade winds usually keep Hilo and Puna areas less affected than Kona and Kohala.
Visit higher elevation areas like Mauna Kea or Waimea, where the air can be clearer, though check for local advisories before driving up.
Indoor or low-exposure activities: botanical gardens, museums, cultural centers, and shopping areas with air-conditioned environments.

Island Hopping / Backup Plans

If vog levels remain high and your health is at risk, you could consider flying to another island. Maui and Kauai generally have clearer air when Kona is affected, but check local air quality reports before booking last-minute flights.
Inter-island flights are frequent but can be expensive if booked last minute. Have a backup plan for accommodations and rental cars if you decide to move islands.

Medical & Safety Tips

Bring any necessary medications and inhalers; consider consulting your doctor before traveling if your heart or lungs are sensitive to air pollution.
Have an emergency plan if symptoms worsen: know the locations of the nearest urgent care or hospital facilities on the Big Island.

Ultimately, the Kona coast is lovely when the air is clear, but vog can fluctuate. By monitoring air quality, planning indoor or wind-protected activities, and keeping inter-island options in mind, you can still enjoy your Hawaii trip while minimizing health risks.
