Lāhainā Noon and Sky Gate by Isamu Noguchi

A unique public sculpture by an American modern master combined with a rare solar event makes for an inspiring viewing event in Honolulu just twice a year.

Lāhainā Noon’s “Cruel Sun”

A special event occurs every year in the tropics where the sun’s rays strike down from directly overhead. Walls and flag poles stop providing shade, and Punxsutawney Phil would definitely not see his shadow. The scientific term for the location where this happens is called the subsolar point.

Hawaiʻi, the only state located in the tropics, has given this phenomenon the nickname “Lāhainā Noon”, with Lāhāina translating literally to ‘cruel sun’ in Hawaiian.¹ In Honolulu, this solar event occurs twice in 2026 on May 26th, 12:28 pm, and on July 16th, 12:37 pm.³

Sky Gate by Isamu Noguchi

Isamu Noguchi completed the public sculpture Sky Gate in 1977. This curvy 24′ high sculpture made from industrial materials lies on the lawn next to the Frank F Fasi Municipal Building. (650 S King St, Honolulu, HI 96813). Noguchi designed Sky Gate as a portal linking the earth and cosmos. Noguchi also described the sculpture as “an evocation to the skies of Hawaiʻi”.² It’s beautiful geometric lines and central location truly make it a focal point of the Civic Center Lawn.

Lāhainā Noon x Sky Gate

Now at Lāhainā Noon, something very peculiar happens at Sky Gate. The typically curvy shadows of the sculpture create a perfect circle lining the concrete base that lies beneath it. A small crowd typically gathers each year for this biannual celestial event. If you’d like to see this in person, check out the info listed below.

• Address: 558 S King Street, Honolulu, HI 96813
• Parking: South King Street has metered parking close to the sculpture, and there’s a nearby municipal parking lot at 346 Alapai St, Honolulu, HI 96813
• 2026 Date/Time: May 26th, 2026 12:28 pm, and July 16th, 2026 12:37 pm.³

At the end of last year, curiosity struck and I revisited Sky Gate. In particular, I wanted to see what the shadow looked like when the sun’s angle was much lower. In mid-November, the circular shadow turned into almost a perfect rounded square.

Both shapes are quite striking when looking at what’s creating the shadow. The forethought to produce these in the only state where this is possible is quite astonishing. In my mind, it’s no wonder that Isamu Noguchi is considered a true modern master.

3. Lāhainā Noon falls on different days in different years. To calculate it yourself for any location in the tropics, you’ll want to go to the NOAA Solar Calculator. Drag the red pin to the location you’re trying to calculate for, and adjust the Day/Month/Time to get elevation (bottom right box, under Az/El) to as close to 90 as possible. For example, Sky Gate in 2025 (Latitude = 21.304451, Longitude = -157.85551) appears to land on May 26, 2025 12:28pm and July 15, 2025 12:37pm.
