Cambridge University Botanic Garden measured 38.7C (101.7F) on Thursday beating the previous UK record of 38.5C (101.3F), set in Kent in 2003.
A Met Office official was sent to check the equipment before verifying the new record on Monday.
Staff working at the garden on Thursday tweeted: “No wonder we all felt as if we’d melted.”
Daily temperatures have been measured by the weather station at the site in the south of the city since 1904.
Cambridge University Botanic Garden director, Beverley Glover, said: “We are really pleased that our careful recording of the weather, something that we’ve been doing every day for over 100 years at the Botanic Garden, has been useful to the Met Office in defining the scale of this latest heatwave.
“Our long history of weather recording is very important to researchers analysing climate change.
“However, we can’t help but feel dismay at the high temperature recorded and the implication that our local climate is getting hotter, with inevitable consequences for the plants and animals around us.”
In fact, Cambridge’s new record tells us very little about “climate change”, but an awful lot about the Urban Heat Island Effect, or UHI.

In late June, one of the most powerful icebreakers in the world encountered such extraordinarily thick ice on-route to the North Pole (with a polar bear specialist and deep-pocketed, Attenborough-class tourists onboard) that it took a day and a half longer than expected to get there.
A few weeks later, in mid-July, a Norwegian icebreaker also bound for the North Pole (with scientific researchers onboard) was forced to turn back north of Svalbard when it unexpectedly encountered impenetrable pack ice.
Apparently, the ice charts the Norwegian captain consulted showed ‘first-year ice‘ – ice that formed the previous fall, defined as less than 2 m thick (6.6 ft) – which is often much broken up by early summer.
However, what he and his Russian colleague came up against was consolidated first-year pack ice up to 3 m thick (about 10 ft). Such thick first-year ice was not just unexpected but by definition, should have been impossible.
Ice charts for the last few years that estimate actual ice thickness (rather than age) show ice >2 m thick east and/or just north of Svalbard and around the North Pole are not unusual at this time of year.
This suggests that the propensity of navigational charts to use ice ‘age’ (e.g. first-year vs. multi-year) to describe ice conditions could explain the Norwegian captain getting caught off-guard by exceptionally thick first-year ice.

There have been many attempts to get rid of the Medieval Warming Period and Little Ice Age, and here’s another one:
The science teams reconstructed the climate conditions that existed over the past 2,000 years using 700 proxy records of temperature changes, including tree rings, corals and lake sediments. They determined that none of these climate events occurred on a global scale.
As with the other failed attempts, this latest one claims that the MWP and LIA were only localised phenomena. But nothing could be further from the truth.
These three new studies rely on proxies, but time and again hockey stick studies based on proxies are proven to be fake, based on cherry picked proxies and dodgy statistics.
In fact, we have no need to rely on proxies, because the actual evidence of warm and cold periods is very real and substantial across the world.
We are all familiar with the evidence from Greenland ice cores, which clearly show both the MWP and LIA:
