Maui in January

How January 2027 scores in Maui

• Overall score

  The main score for Maui in January 2027, from 1 to 10, where 10 is best for the visitor. Weather counts for 40%, crowds 25%, daylight 10% and uniqueness 25%. Air quality is shown on its own. How we score

  Overall: not shown. It needs weather and at least two of the other three aspects, and crowds and uniqueness are not measured for this month.

• Weather

  9/10 9/10 Ideal

  Weather 9/10: the average high is 82.2 °F with 61.5 mm of rain (1991–2020 normals, NOAA National Centers for Environmental Information (NCEI)). That high is inside the 70–86 °F comfort band, so only rain lowers the score.

  How this was scored

  • NOAA National Centers for Environmental Information (NCEI), KAHULUI AP, HI US (USW00022516), 1991–2020 normals (www.ncei.noaa.gov, checked 2026-10-17)
  • The data file read (www.ncei.noaa.gov, checked 2026-10-17)

  high 82.2 °F: no deduction; rain 61.468 mm: −1.23; 10 − 1.23 = 8.77 → 9

• Crowds

• Daylight

  6/10 6/10 Average

  Daylight 6/10: in January 2027 the sun is up for 11 h 2 min a day on average, from sunrise to sunset at 20.90° N, 156.43° W (NOAA solar equations).

  How this was scored

  • Destination point 20.90° N, 156.43° W, the weather station's published coordinates (www.ncei.noaa.gov, checked 2026-10-17)
  • Sunrise and sunset by the NOAA Solar Calculator equations, checked against NOAA's own Solar Calculator code (the US Naval Observatory's service didn't answer us) (gml.noaa.gov, checked 2026-10-17)

  mean of 31 days from sunrise to sunset: 11 h 2 min (11.03 h); 1 + 1.5 × (11.03 − 8) = 5.55 → 6

• Uniqueness

  Not measured

  Uniqueness: not measured. The County of Maui calendar didn't cover this month when it was checked. See How we score.

• Air quality

  10/10 10/10 Mostly good air

  Air quality 10/10: 88 of 92 measured days in January (2023–2025) were in EPA's Good range for fine particles (PM2.5 at 9.0 µg/m³ or less), at 2 monitors within 25 miles.

Maui through the year: scores out of 10, where 10 is best for the visitor; * marks a provisional score, explained on that month's page

Scores summarize official data with the method on How we score. They aren't a recommendation, and any given year can differ.

When to go

January is inside the peak whale season that NOAA's sanctuary gives as January through March, within a season that generally runs from November through April. NOAA's sanctuary page says the Great Whale Count takes place on Maui on the same dates as its Ocean Count, which is held on the last Saturday of January, February and March. The month is outside the official Central Pacific hurricane season, although the Central Pacific Hurricane Center says tropical cyclones can occur at any time. The State of Hawaii's holiday schedule lists New Year's Day and Dr. Martin Luther King, Jr. Day, so check how those holidays fall against your travel dates.
