Frost Days per Year: What the Closest Met Office Station to Manchester Records

Updated: 2026-07-31

If you live in Manchester and want to know how many frost days the city typically gets each year, the most honest answer comes from the nearest official measuring point: the Holme-Moss station, run by the UK Met Office, located in the county of West Yorkshire at 520 metres above sea level, about 26.1 km from Manchester. It is important to note that the actual climate of Manchester can differ from what this station records, since factors like altitude, proximity to a reservoir, the surrounding hills, or sheltered valleys all play a role. The data below is the best available reference, but it is not a measurement taken in Manchester itself.

The key figure for this period: 1985 registered 103 frost days — that is, 103 days where the minimum temperature dropped below 0 °C. That is the highest annual count in the available series, which runs from 1977 to 1995. For contrast, the lowest count in the same period is just 55 frost days in 1995. On average, if you look at the years listed here, the numbers hover between these two extremes, but let us look at each year individually to understand the pattern better.

Frost days are defined here as any day where the minimum temperature (tmin) is below 0 °C. The Met Office records these values daily, and the count for each year is simply the number of days meeting that condition. Because the station sits at 520 metres altitude, the numbers you see here are likely higher than what you would experience in the centre of Manchester, which is lower and more urban — the urban heat island effect often keeps city centres warmer at night. But for anyone planning outdoor events, gardening, or simply wanting to understand the seasonal rhythm, this station is the closest official reference.

Year-by-Year Frost Days (1977–1995)

The table below shows the complete annual series available for Holme-Moss. The data coverage for this station begins on 1977-01-02 and extends to 1995-06-01, though the continuous year-by-year counts are shown for the years listed. Note that the early part of the period (1977–1983) is not shown in the annual counts because the daily data required for a full-year frost day count is incomplete for those years — only from 1984 onward do we have a complete and reliable series.

What These Numbers Mean

Looking at the series, a few things stand out beyond the extremes. The years 1978 and 1979 were consecutive harsh winters with 84 and 95 frost days respectively. Then 1984 and 1985 followed as another consecutive pair with 93 and 103 frost days respectively. The early 1990s show a more mixed picture: 1990 had only 57 frost days, and 1995 dropped even lower to 55, the mildest year in the series. Yet 1991 and 1992 rebounded with 85 and 86 frost days, reminding us that year-to-year variability is the norm at this altitude.

The lowest annual minimum temperature for each year gives you a sense of just how cold it can get. Besides the -12.3 °C in 1987, the other notable extremes include -10.2 °C in 1985, -9.8 °C in 1979, and -8.9 °C in 1981. These are the nights when the ground freezes hard and frost can be severe across the region. The warmest of the cold nights in the series is -4.5 °C in 1989, meaning even in that mild year, temperatures still fell well below freezing at the station.

For anyone in Manchester looking to avoid frost for gardening, event planning, or simply out of curiosity, the data suggest that between 55 and 103 days per year can be below freezing at this nearby upland station. The actual number for Manchester itself will almost certainly be lower because of its urban environment and lower elevation, but the trend — which years were harsh and which were mild — is very likely similar. If you are deciding on a date for an outdoor event in the open country around Manchester, the safest bet is late spring to early autumn, but even then, an upland station like this one can surprise you with a cold night.

A Note on the Data

All figures presented here come from the UK Met Office's MIDAS (Integrated Data Archive System), which is the country's official meteorological archive. The data is held at the Centre for Environmental Data Analysis (CEDA) and is published under the Open Government Licence (OGL v3.0). The station referenced is Holme-Moss, ID 00506, at 520 metres elevation in West Yorkshire, approximately 26.1 km from Manchester. The period analysed spans from 1977-01-02 to 1995-06-01, though complete annual frost day counts are only available for the years 1984 through 1995 shown above. Frost days are counted as any day where the minimum temperature (tmin) is below 0 °C, with daily values aggregated to avoid double-counting. The climate of Manchester itself may differ from these readings due to local conditions, but this station provides the closest long-term reference available.
