The hottest day ever recorded at Leeds Weather Centre came on 2 August 1990, when the thermometer reached 34.4°C — the station's absolute maximum temperature. That same year, the city saw 6 days above 28°C, and the mercury topped 23°C on 35 separate occasions.
That 34.4°C reading remains the standout extreme for the 1985–2004 period analysed here, a figure that puts even the warmest summers of the early 2000s in the shade.
The Met Office's official station at Leeds Weather Centre (network ID 00523 in the national MIDAS archive) provides a continuous daily record from 1 November 1985 through 11 August 2004. Using this near-20-year series, we can answer a simple but telling question for anyone living in or visiting Leeds: how many genuinely hot days arrive each year?
For this analysis, three thresholds matter:
The full annual breakdown below shows how wildly these counts can swing from one summer to the next.
Five dates stand out as the most extreme of the whole period, all above 31°C:
| Date | Maximum temperature |
|---|---|
| 2 August 1990 | 34.4°C |
| 3 August 1990 | 34.2°C |
| 9 August 2003 | 31.8°C |
| 18 June 2000 | 31.7°C |
| 2 August 1999 | 31.4°C |
Notice how the top two belong to the same heatwave of early August 1990 — the only time the station saw consecutive days above 34°C in this record. The summer of 2003, famous for the European heatwave, contributes the third spot with 31.8°C, while June 2000 shows that extreme heat can strike before the school holidays even begin.
Here is the complete annual count of days exceeding 28°C at Leeds Weather Centre. The table also includes the year's highest temperature and, for context, the number of days at or above 26°C and 23°C:
The chart shows the complete annual series. The table lists the most notable years; the full series comes from Met Office.
| Year | Days >28°C | Days ≥26°C | Days ≥23°C | Annual max temp |
|---|---|---|---|---|
| 1985 | 0 | 0 | 0 | 16.0°C |
| 1989 | 8 | 17 | 41 | 31.1°C |
| 1990 | 6 | 14 | 35 | 34.4°C |
| 1995 | 16 | 26 | 46 | 31.1°C |
| 1999 | 4 | 15 | 38 | 31.4°C |
| 2000 | 3 | 5 | 22 | 31.7°C |
| 2003 | 9 | 15 | 43 | 31.8°C |
The extremes of the series are striking. 1995 stands apart with 16 days above 28°C — more than double any other year in the period. That same year delivered 26 days at or above 26°C and 46 days at or above 23°C, making it the benchmark hot summer of the late 20th century in Leeds.
At the other end, 1985 recorded zero days at any of the three thresholds, with a highest temperature of just 16.0°C — a year that never even came close to what most residents would call a warm day. The year 2004 likewise shows zero days above 23°C, though the station record ends in August of that year, so the count only reflects part of the summer.
Extreme heat in Leeds is not spread evenly through the year. Looking at the average number of days above 28°C per month (computed across the full period), August is clearly the peak month:
| Month | Average days >28°C |
|---|---|
| May | 1.0 |
| June | 1.5 |
| July | 2.3 |
| August | 3.3 |
| September | 1.0 |
August alone averages more than three days of extreme heat per year, far ahead of July's 2.3 days. The record-breaking heat of 2–3 August 1990, followed by the 31.8°C of 9 August 2003, confirms that early-to-mid August is the window when Leeds is most likely to roast. Interestingly, May and September each average exactly 1.0 days — extreme heat can arrive right at the fringes of summer, but it never does so consistently.
For anyone living in Leeds, these numbers translate into an expectation of roughly 3 to 4 truly hot days per year in an average summer — but with enormous variation. The leap from 1 day above 28°C in 1986 to 16 days in 1995 shows that "typical" weather is almost a fiction in this city. The 1990 heatwave, with its two consecutive days above 34°C, remains the kind of event that happens once in a generation: nothing in the subsequent 14 years of this record came close.
The 1985–2004 series reveals no steady upward march, but rather a pattern of intense episodic heat. Years like 1989, 1990, 1995, 1999, and 2003 cluster as the hot ones, while 1985, 1993, 1998, and 2004 stayed resolutely cool. The 2003 summer, which featured 9 days above 28°C, shows that even without surpassing 32°C, an extended warm spell can dominate a season.
These counts come straight from the Met Office's national weather station network, archived in the MIDAS system and accessible to the public under the Open Government Licence. The Leeds Weather Centre record, spanning from 1 November 1985 to 11 August 2004, is a reliable, quality-checked series that excludes provisional or inconsistent readings.
Whether you're planning an outdoor wedding, deciding when to schedule a festival, or simply curious about how today's summers compare to those of your childhood, this annual count of extreme heat days gives you the ground truth. The answer to "how many extreme heat days does Leeds get?" is not a single number but a spectrum: from zero in cool years like 1985, to a remarkable 16 days in 1995, with a long-term monthly peak in early August.
