- Two-day release

- NPS limits you to one sunrise reservation per 3-day period, so you cannot hold a backup morning in the same stretch.
- Reservations are not refunded or exchanged for weather, and the reservation holder must be present with ID.
- Calling or visiting in person will not get you a reservation.
Dates are computed from NPS’s rule (about 60 days ahead, plus a portion 2 days ahead, both at 7:00 a.m. HST). Recreation.gov shows the exact opening for your date. NPS sunrise page →
How often is it clear?

Plan the morning
Your sunrise morning, in order
- Summit entry window opens
Vehicles entering the Summit District between 3:00 and 7:00 a.m. need a sunrise reservation.
- The sky starts to glow
Civil twilight. Be parked and bundled up before this; the color build-up is often the best part.
- Sun clears the horizon
Sunrise bearing — from the summit.
- Reservation window ends
Entry rules go back to normal after 7:00 a.m.
The road climbs a long series of switchbacks to the summit. Most visitors from the Kahului and south-shore resort areas allow roughly two hours of driving, and less from Upcountry. Parking is limited to designated lots and closes when full, and the entrance gate is about 30 minutes from the summit, so arrive early. Check road and parking notices on the NPS page before leaving.

Dress for winter
The National Park Service warns that summit temperatures can drop below freezing around dawn, and wind makes it feel colder. Bring a warm jacket, hat and gloves, long pants and closed shoes, even if the beach you left was 78°F.
Expect thin air
At 10,023 feet, the air holds roughly 30 percent less oxygen than at sea level. Walk slowly, drink water, and watch for headache, dizziness or nausea. People with heart or lung conditions, and anyone pregnant, should talk to a doctor before going.
Bring something to sit on
Many visitors wait 30 to 60 minutes in the cold before the sun appears. A blanket, a thermos and a small flashlight make the wait far more comfortable.
If it is clouded in
Your plan B on the same road
Go lower, not home
NPS points to Leleiwi and Kalahaku overlooks as the quieter alternatives to the summit at dawn. They sit lower on the same road, so conditions there can differ from the summit. Nothing here predicts that, so look at the sky as you climb.
Decide where you are driving from
Allow about two hours from Kahului and the south-shore resorts. Summit sensors count from eight hours before sunrise, so check this page when you wake and again before you leave the hotel, not at the gate.
Know what you cannot change
The reservation is not refunded or exchanged for weather, and only one is allowed per 3-day period. If the call is poor, the choice is between going anyway for the crater at daylight or keeping the morning free.
Where the clouds are
Moisture compared with the summit
The summit of Haleakalā stands 10,023 feet above the Pacific on the rim of a crater roughly seven miles long. It often sits above Maui’s low trade-wind cloud, but not every morning. Generic “cloudy” forecasts describe the lowlands. What matters up here is the humidity at three heights: below the summit, at summit level, and above it. Cloud that sits below you becomes a glowing sea; cloud at summit level means fog and wind.

Are the clouds mainly below the summit?
INSUFFICIENT EVIDENCE
This inference is intentionally cautious. Cloud below summit elevation does not guarantee a clear summit.
This component uses the vertical moisture profile as context. It is never a guarantee of being above the clouds.
What could go on
What each call means, and what flips it
Good odds of a clear sunrise
Dry air at summit level and a dry, steady summit reading. Small cap clouds can still form, so it is not a guarantee.
Flips if: summit humidity climbs quickly, or a wind or winter warning is issued.
Could go either way
Humidity at the summit is moving fast, or the forecast and the summit sensors disagree. The view now may not be the view at sunrise.
Resolves when: the trend settles. Recheck shortly before you leave.
Plan for fog, cloud or rain
Moist air at summit level, a wet summit reading, or a high-impact warning. Reservations are not refunded for cloud, so decide with this in mind.
Flips if: the air dries out and the summit trend improves before sunrise.
Not enough evidence
Key data is missing, stale or too far ahead of sunrise to count. The tool abstains rather than guess.
Resolves when: summit readings fall inside the eight-hour decision window before sunrise.

Ticket availabilityNot claimed
NPS releases reservations up to 60 days ahead and a portion two days ahead at 7:00 a.m. HST. If the call is poor, lower viewpoints on the same road, such as Leleiwi Overlook or the Haleakalā Visitor Center, can still be worth the drive. Confirm on the NPS page what your reservation covers.
For the curious and the cautious
The evidence behind the call
Everything above comes from these sources, using vertical GFS moisture, measured summit humidity and trend, hazards, access, sunrise geometry and live imagery. Each row shows what kind of evidence it is and how fresh it is.
LOADINGCurrent evidence
Retrieving source data and timestamps.
Safety
Hazards can override visibility
- Checking active NWS alerts for the summit point.
An active high-impact wind or winter warning is a hard decision gate even if the visibility signal is otherwise favorable.
Live spatial evidence
Haleakalā all-sky camera
Checking whether the newest LCO image is fresh enough to use.
Imagery corroborates the decision only when freshness can be verified. A stale camera is explicitly excluded.

- Loading sources…
Generic total-cloud wording is context only. It does not select FAVORABLE, CHANGING, UNFAVORABLE or UNCERTAIN.
How to use this result
Use the call, confidence and freshness together
Recheck close to departure. FAVORABLE is not a guarantee, CHANGING means conditions may not persist, and UNCERTAIN means the evidence is not strong enough to justify confidence.
The questions visitors actually ask
How to read Haleakalā sunrise weather
Will Haleakalā sunrise be cloudy?
A sea-level or generic total-cloud forecast is not enough. Haleakalā reaches 10,023 feet, so the important question is whether moisture and cloud are at summit level, below it, or changing toward it.
Can the summit be clear when an app says “cloudy”?
Yes. Low marine cloud can cover much of Maui while the summit sits above that layer. This tool therefore uses the vertical atmospheric profile and summit observations rather than total cloud percentage as the core signal.
Will I definitely be above the clouds?
No. The above-cloud component is experimental. Local cap cloud, fast transitions and small-scale cloud can obscure the summit even when the broader moisture layer is lower.
How cold and windy can sunrise be?
The page shows the NWS near-sunrise temperature and wind, plus a calculated wind-chill. Haleakalā National Park warns that summit conditions can change rapidly and can be below freezing around dawn.
Do I need a reservation?
For vehicle entry to the Summit District from 3:00–7:00 a.m. HST, NPS requires a sunrise reservation. This tool links to the official booking page but does not invent live ticket availability.
What if the summit is clouded in?
The reservation is not refunded for cloud. Lower viewpoints on the same road can sit below the cap cloud, and daylight views of the crater can still be striking. Check the call again before you leave the car.
When should I check this page?
Summit sensors only count toward the call within eight hours of sunrise. Check the evening before for the forecast picture, then again before you leave for the mountain.
What does LOW confidence mean?
It means key evidence is missing, stale, contradictory, or near an operating threshold. LOW confidence does not get silently converted into a favorable answer.
Method boundary
No sunrise score. No beauty prediction. No guaranteed horizon.
The decision engine uses deterministic rules. A dry 700 hPa profile can support a favorable call, but it cannot overrule a wet or rapidly changing summit observation. Boltwood sky-minus-ambient temperature is supporting evidence only. Camera and satellite-style spatial evidence are corroboration, not ground truth. When evidence is missing or contradictory, the valid answer is UNCERTAIN or CHANGING.
