What the weather is like
The Kīlauea summit area sits above 4,000 feet. It is cooler than the coast, mornings and evenings get cold (especially in winter), and rain is common. Kona can be hot and sunny the same morning, so pack for both. Mauna Kea is colder again: evenings at the visitor station can drop to about 30°F.
For today’s forecast, check the National Weather Service before you drive.

Keep a warm layer in the car for dusk, when the crater glow (if lava is active) is at its best. See lava viewing.
Mauna Kea summit or stargazing
- A real jacket
- Hat
- Long pants
- Closed-toe shoes
- Water in the car
Evenings at the visitor station can drop to about 30°F. Most tours lend parkas and gloves; check yours. Altitude can bring headaches, nausea and tiredness, so spend at least half an hour at the visitor station before going higher. More on Mauna Kea tours.
If you are on a tour
Ask what is included: some volcano tours include lunch, others stop at a bakery where you pay your own way. Bring a layer either way; the van is warm, the crater rim is not.
