Sources and checks for this page
Live readings come from METAR reports from the aerodrome at Guernsey Arpt. 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.
19.6°F between August and February, the 100th 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 Saint Peter Port right now?+−
51.8°F at Guernsey Arpt, measured at 12:20 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 Saint Peter Port?+−
The archive held here for Saint Peter Port, Guernsey starts in 1959, which is 67 years of record, and 47,589 stored daily values, each one a maximum or a minimum.
Which station measures Saint Peter Port's temperature?+−
Guernsey Arpt (EGJB), 102 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 Saint Peter Port's record?+−
The record runs from 1959 to 2026, and it is not equally deep across the year: the thinnest of the 12 months has 65 years of readings behind its average and the fullest has 67. 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 Saint Peter Port getting hotter?+−
In its hottest month it has. Across 67 Augusts between 1960 and 2026, the average August high at Guernsey Arpt 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 Saint Peter Port compare with other capitals?+−
It is the 202nd 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 100th by the width of its annual swing. Saint Helier, Brussels, Prague sit closest to it on that ranking.
