Sources and checks for this page
Live readings come from METAR reports from the aerodrome at Port Moresby Intl. Monthly means and every record on this page are computed from NOAA GHCN-Daily observations stored per station, per year, per month, and the capital list is GeoNames, CC BY 4.0. Nothing here is modelled, interpolated or estimated, and a month the archive never covered is left out rather than filled in. See how this is built.
4.7°F between November and July, the 200th widest swing among the 230 capitals ranked here. The big figure on each card is the average high for that month across the whole record; the two lines beneath it are the hottest and coldest days ever recorded in it.

What is the weather in Port Moresby right now?+−
82.4°F at Port Moresby Intl, measured at 23:00 local on Thursday, 12 November 2026. This is the live reading from the station this page reads, after our quality checks. It is an observation rather than a forecast: it says what the weather IS, not what it will be.
When did temperature records begin in Port Moresby?+−
The archive held here for Port Moresby, Papua New Guinea starts in 1970, which is 33 years of record, and 24,433 stored daily values, each one a maximum or a minimum.
Which station measures Port Moresby's temperature?+−
Port Moresby Intl (AYPY), 44 m above sea level. Every figure on this page comes from that one station rather than from a city-wide average, so it is a measurement at a known place rather than an estimate for an area.
How is the temperature measured and checked?+−
Readings arrive from METAR reports from the aerodrome and are quality controlled before they appear: a value outside a plausible range, or one that jumps further than air can move in the time between readings, is rejected rather than published. Every figure shows its source and the time it was observed.
Are there gaps in Port Moresby's record?+−
The record runs from 1970 to 2003, and it is not equally deep across the year: the thinnest of the 12 months has 33 years of readings behind its average and the fullest has 34. Gaps are left as gaps: a month the archive never covered is omitted rather than filled in, which is why some months on this page carry no record.
Is Port Moresby getting hotter?+−
In its hottest month it has. Across 33 Novembers between 1970 and 2002, the average November high at Port Moresby Intl has risen about 0.2°F per decade. That is a straight-line fit through this one station's record: it is not corrected for a station that moved or changed instrument, and it is a description of the readings rather than a climate attribution.
How does Port Moresby compare with other capitals?+−
It is the 44th warmest of the 230 capital cities with a full twelve months of record here, ranked on annual mean rather than on any single day, and 200th by the width of its annual swing. Santo Domingo, Panama City, Tarawa sit closest to it on that ranking.
Why is Port Moresby hotter in November than in January?+−
November averages a high of 90.3°F here and January 89.6°F, so the hottest part of the year arrives -10 months before midsummer and the afternoons are 0.7°F cooler by the time the sun is highest. The month cards above show the rise and the fall. These are temperature readings, so they show that shape rather than what causes it: nothing on this page measures cloud, rain or wind.
Commentary: Warm enough to make the shade worth considering.
