75.6°F at Honiara, measured at 05:00 local on Friday, 13 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 Honiara?+−
The archive held here for Honiara, Solomon Islands starts in 1952, which is 73 years of record, and 11,608 stored daily values, each one a maximum or a minimum.
Which station measures Honiara's temperature?+−
Honiara (WMO 91517), 55 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 WMO SYNOP bulletins 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 Honiara's record?+−
The record runs from 1952 to 2025, and it is not equally deep across the year: the thinnest of the 12 months has 9 years of readings behind its average and the fullest has 16. 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 Honiara getting hotter?+−
In its hottest month it has. Across 13 Januarys between 1993 and 2025, the average January high at Honiara has risen about 0.5°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 Honiara compare with other capitals?+−
It is the 29th 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 226th by the width of its annual swing. Port-au-Prince, Kingston, Bandar Seri Begawan sit closest to it on that ranking.
When is Honiara hottest?+−
January, averaging 90.1°F across the record, with August the coolest at 88.7°F. That is a swing of 1.4°F across the year.
