The highest temperature recorded during any summer at the measuring point closest to Birmingham was 34.7 °C, reached in 1990. That same summer also produced a seasonal average daily maximum of 21.9 °C.
Summer maximum temperature — Halesowen station, 1990
The point of measurement closest to Birmingham is the Halesowen station in West Midlands, standing at 153 m above sea level, roughly 13.3 km from the city. It is not a Birmingham station, and its records do not describe Birmingham's climate exactly — local differences in elevation, terrain and surroundings all shift what a thermometer reads. But it is the nearest long-running record available, and its June–August series covers the full summers from 1956 to 2003. Here is what it shows.
Across those 48 full summers, the seasonal average daily maximum ranged from 18.0 °C — recorded in both 1956 and 1972 — up to 23.5 °C in 1976. That 1976 figure stands as the warmest summer average in the Halesowen record, and its peak day hit 32.6 °C. It is worth pausing on 1976: an average daily maximum of 23.5 °C across an entire June, July and August is a genuinely exceptional run, and nothing else in this series comes close to it.
Yet the single hottest day did not fall in 1976. That came in 1990, when the mercury touched 34.7 °C. The same year's summer average was 21.9 °C, well above the cool years but several degrees below the 1976 average. So the two measures tell different stories: 1976 was the most consistently warm summer, while 1990 delivered the sharpest single spike of heat.
| Year | Average daily maximum (°C) | Highest temperature that summer (°C) |
|---|---|---|
| 1976 | 23.5 | 32.6 |
| 1983 | 22.9 | 32.1 |
| 2003 | 22.6 | 33.1 |
| 1975 | 22.4 | 32.6 |
| 1984 | 22.4 | 29.9 |
Two entries share fourth place in that list, both at 22.4 °C — 1975 and 1984. What stands out is how many of the warmest summers sit in the 1970s and 1980s, with 2003 the only entry from the final decade of the record. The 1990s were by no means uniformly hot: 1993 averaged 19.9 °C, and 1998 came in at 19.4 °C.
The table below lists each full summer in the record. Two years are absent from this series — 1995 and 2004 — because their records were incomplete, so they are not shown here as seasonal averages. A summer is defined here as June, July and August.
The chart shows the complete summer average daily maximum by year. The table lists the most notable years; the full series comes from Met Office.
| Year | Average daily maximum (°C) | Highest temperature (°C) | Days counted |
|---|---|---|---|
| 1956 | 18.0 | 25.0 | 92 |
| 1957 | 20.1 | 28.9 | 92 |
| 1958 | 19.0 | 26.1 | 92 |
| 1959 | 21.4 | 28.3 | 92 |
| 1960 | 19.7 | 28.3 | 92 |
| 1961 | 19.2 | 29.4 | 92 |
| 1967 | 20.3 | 28.3 | 91 |
Look at the 1960s: 1962 averaged 18.2 °C, 1963 reached 18.8 °C, and 1965 mustered 18.5 °C. Apart from 1961 (19.2 °C against a peak of 29.4 °C) and 1969 (20.6 °C with a peak of 30.1 °C), the decade rarely climbed above 20 °C in seasonal average. The 1950s opened with the joint-coolest summer of the whole record, 1956 at 18.0 °C and a peak of just 25.0 °C.
Contrast that with the closing years. The final decade's entries — 1994 at 21.5 °C, 1996 at 21.3 °C, 1997 at 21.5 °C, 1999 at 20.9 °C and 2003 at 22.6 °C — cluster noticeably higher than the 1960s. But the record also contains distinctly cool later summers: 1998 at 19.4 °C and 1993 at 19.9 °C, plus 1985 at 18.9 °C and 1988 at 19.2 °C. The trend is not a smooth climb; it is a series of warm years layered over a cooler baseline.
For context, the warmest summer averages anywhere in the UK station network sit a step above what Halesowen typically records. Heathrow, in Greater London, averages 22.3 °C across its 78 years of summer data — the highest in the country — with a mean summer temperature of 17.6 °C. Northolt, also in Greater London, follows at 22.2 °C over 74 years, and Santon Downham in Suffolk matches that 22.2 °C figure across 37 years. Cavendish, also Suffolk, averages 22.0 °C over 49 years.
London's St James's Park brings 110 years of records to its 21.9 °C summer average, and Hampton in Greater London reaches the same 21.9 °C across 42 years. East Bergholt in Suffolk averages 21.8 °C over 62 years, as does Aldenham School in Hertfordshire over 43 years and Writtle in Essex over 67 years. High Beach in Essex closes the list at 21.7 °C over 48 years.
The picture is clear: the warmest places in Britain for summer heat sit in the south-east, and Halesowen's 1976 average of 23.5 °C would top even Heathrow's long-term figure — a reminder that individual exceptional summers can outrun the regional averages entirely.
If you remember long, hot summers from your youth in Birmingham, the Halesowen record supports part of that memory and complicates another part. Summers like 1975 (22.4 °C average), 1976 (23.5 °C) and 1983 (22.9 °C) were genuinely outstanding. But the 1960s and much of the 1980s were far cooler than nostalgia tends to recall — 1962 averaged 18.2 °C, and 1985 came in at 18.9 °C. Meanwhile the 1990s delivered both the single hottest day of the record, 34.7 °C in 1990, and several summers that would have felt unremarkable.
Bear in mind that these are measurements from a single site at 153 m elevation, 13.3 km from Birmingham city centre. Urban heat, local topography and shelter all influence what a particular garden or street experiences on a given day. The station is the best long-run reference available for the area, but it is one point on the map, not the whole picture.
