Question 1

How many hours of daylight does Port Moresby get today?

Accepted Answer

Port Moresby currently gets approximately 11 hours and 58 minutes of daylight today. This varies throughout the year — days are longest around the summer solstice (June in the Northern Hemisphere, December in the Southern Hemisphere) and shortest around the winter solstice. Because Port Moresby is near the equator, day length stays relatively consistent, typically between 11 and 13 hours. Our calculations use the SunCalc astronomical library for accuracy within 1–2 minutes.

Question 2

What time does the sun rise in Port Moresby?

Accepted Answer

Sunrise times in Port Moresby change throughout the year based on the Earth's axial tilt and the city's position at 9.4° latitude. Use the table above to see today's exact sunrise time, as well as dawn (civil twilight) and other twilight phases. The earliest sunrise typically occurs around the summer solstice, while the latest sunrise happens near the winter solstice. Near the equator, sunrise times vary by less than an hour across the year. All sunrise calculations are based on NOAA solar position algorithms via the SunCalc library.

Question 3

What time does the sun set in Port Moresby?

Accepted Answer

Sunset times in Port Moresby vary by season due to the Earth's orbital mechanics and the city's latitude of 9.4°. Check the table above for today's exact sunset time, including dusk and twilight phases. The latest sunset typically occurs a few days after the summer solstice, while the earliest sunset happens a few days before the winter solstice. Near the equator, sunset times remain fairly consistent throughout the year, typically varying by less than an hour.

Question 4

How does day length change throughout the year in Port Moresby?

Accepted Answer

Port Moresby is located near the equator at 9.4° latitude, so day length varies relatively little throughout the year — typically between about 11 and 13 hours. The sun rises and sets at roughly the same time year-round, and twilight transitions are short and abrupt compared to higher latitudes. This consistency makes Port Moresby one of the more predictable locations for planning outdoor activities. The slight variation that does occur peaks around the equinoxes in March and September.

Question 5

What is civil twilight in Port Moresby?

Accepted Answer

Civil twilight in Port Moresby is the period when the sun is between 0° and 6° below the horizon. During civil twilight, there is enough natural light for most outdoor activities without artificial lighting. It occurs just before sunrise (dawn) and just after sunset (dusk). Near the equator, civil twilight is relatively short, typically lasting only 20–25 minutes. The exact duration for Port Moresby is shown in the twilight data table above.

Question 6

What are the different twilight phases?

Accepted Answer

There are three twilight phases, each defined by the sun's angle below the horizon. Civil twilight (0°–6°) is the brightest phase, with enough light for outdoor activities without artificial lighting. Nautical twilight (6°–12°) is dimmer but still allows sailors to see the horizon for celestial navigation. Astronomical twilight (12°–18°) is nearly dark, with only the faintest glow on the horizon, and most stars become visible. Below 18° is considered full astronomical night. The duration of each phase varies by latitude and season — our data table above shows all twilight phases for Port Moresby.

Question 7

When is the longest day in Port Moresby?

Accepted Answer

The longest day in Port Moresby occurs around the summer solstice. For Port Moresby in the Southern Hemisphere, the longest day is around December 21–22. On this date, Port Moresby experiences its earliest sunrise and near-latest sunset of the year. Near the equator, the longest day is only slightly longer than the shortest, differing by about 1–2 hours. The shortest day (winter solstice) occurs approximately six months later.

Question 8

Does daylight saving time affect sunrise and sunset times in Port Moresby?

Accepted Answer

Port Moresby does not observe daylight saving time, so sunrise and sunset times change only due to natural seasonal variation throughout the year. The gradual shift in sunrise and sunset times follows a smooth curve driven by the Earth's axial tilt and orbital position. This makes it easier to predict sunrise and sunset patterns in Port Moresby compared to cities that observe DST, where clock changes create abrupt jumps in the schedule.
