The latest spring frost in Leeds between 1986 and 2003 hit on 28 April 1995, when the mercury dropped to -0.4°C. That is the last date you can expect a killer frost — after that, tender plants are safe.
But the most extreme cold recorded at Leeds Weather Centre during this entire period came much earlier in the year. On 11 February 1986, temperatures plunged to -8.5°C. That winter freeze is a reminder that while spring frosts are the gardener's concern, the deepest cold arrives well before the growing season begins.
For anyone planting tomatoes, dahlias, or runner beans in Leeds, the question of when the last frost will strike is not academic. A single night below zero can blacken tender shoots and undo weeks of careful cultivation. The data from the Met Office's Leeds Weather Centre station gives us a clear picture of what to expect — and when to stop worrying.
The frost window closes much earlier than many gardeners fear. Across the years analysed, the latest spring frost occurred on 28 April 1995, but that was the exception rather than the rule. In most years, the danger has passed by early to mid-April. The 1990 season saw its final frost on 9 April, with a minimum of -1.0°C. In 1986, the spring frost season finished on 7 April at -0.1°C.
Some years are dramatically kinder. In 1992, the last frost struck as early as 17 February, with a minimum temperature of -0.8°C. The following year, 1993, the final frost came on 27 March at -0.4°C. Even a mild winter like 1991 saw its last sub-zero reading on 19 February at -0.1°C.
The chart below shows the date of the last spring frost for each year in the record, alongside the temperature recorded on that day. Notice how the dates cluster in April — that is your planning window.
The chart shows the complete annual series. The table lists the most notable years; the full series comes from Met Office.
| Year | Last frost date | Minimum temperature (°C) |
|---|---|---|
| 1986 | 1986-04-07 | -0.1 |
| 1991 | 1991-02-19 | -0.1 |
| 1994 | 1994-04-11 | -1.3 |
| 1998 | 1998-04-16 | -0.3 |
| 2000 | 2000-04-15 | -0.2 |
| 2001 | 2001-04-21 | -0.2 |
| 2002 | 2002-03-12 | -0.1 |
Look at the pattern. The frost dates appear in two distinct clusters. The earliest finishes — 1991, 1992, 1993, 1997, 2002, and 2003 — all ended before April. But the majority of years pushed the last frost into April, with the 1988 and 1989 seasons ending on 24 and 26 April respectively. The 1995 record of 28 April stands as the single latest frost in the entire record.
What does this mean for your garden? If you plant tender annuals before mid-April, you are gambling with at least a 1.2-day monthly average frost risk. The table below shows the average number of days with frost for each month, calculated across the full period of records.
| Month | Average frost days |
|---|---|
| January | 6.0 |
| February | 6.3 |
| March | 3.4 |
| April | 1.2 |
| October | 0.9 |
| November | 2.7 |
| December | 5.8 |
These numbers tell a clear story. February is the frostiest month, with an average of 6.3 frost days — even frostier than January's 6.0. The coldest reading in the record, the -8.5°C of 11 February 1986, fits perfectly with this pattern. The deep winter cold is the real killer, but by April the risk is already fading to an average of just 1.2 frost days.
The practical gardening takeaway is this: for Leeds, the safe planting date for frost-sensitive plants is after 28 April, the latest frost ever recorded in this period. But in most years, you could plant in the third week of April without incident. The middle of May is always safe — by then, the average April frost day has long passed, and October's 0.9 average frost days are still months away.
The record also shows how mild some years were. The 1991 and 1992 seasons ended in February, meaning those years saw no frost at all after 19 February and 17 February respectively. Those are the years when a cold frame might never be needed. But 1995 stands as the warning: even in a relatively modern period, a frost can strike as late as the final days of April.
All data comes from the Met Office's Leeds Weather Centre station, covering the period from 1 November 1985 to 11 August 2004. This is the same official record used by the UK national meteorological service, held in the MIDAS archive. The frost definition used here is any day where the minimum temperature fell below zero degrees Celsius, between the months of January and June — the window that matters for spring planting.
For the Leeds gardener, the message is simple: watch the forecast after mid-April, but do not panic before early April. The chances of a frost after the 28 April record are effectively zero based on this data. And if you want to be extra cautious, wait until the first week of May — by then, the average April frost days have dwindled to nothing, and your tender plants can go in the ground with confidence.
