Umbrellas and water are the order of the day for Emma Julian and Andrew Smith, who are at Wimbledon after flying in from the US.
They've been queuing since 5.30am to get into the SW19 venue, and it's been sunny all morning.
"We did not expect it to be like this," said Emma.
Megan and her friends showed up even earlier, just before 5am.
As excited as they are to be there, they feel more could have been done by the organisers to protect visitors from the heat.
"The queues for water are ridiculously long," they said.
"But it is all worth it to go in."
Mya Jones, however, may be among the most committed tennis fans there today.
Flying in from New York City, she's number 83 in line to enter tomorrow - and she's sleeping out in the open there to claim her spot first thing.
"It's elegant, and it encompasses all the wonderful things about tennis you want," she said, when asked why she loves Wimbledon.
Wimbledon's chief executive, Sally Bolton, said there were more than 100 water points around the ground and a "significantly sized medical team" to help where needed.
"We're not used to these sort of temperatures but we're absolutely ready for it and actually delighted that it's sunny and not wet like it was last year," she added.
Alzheimer's Society is urging the public to check in on friends and family living with dementia.
In this spell of hot weather, the charity has shared a list of tips to support them:
From UVA to UVB and SPF, there are a few things to untangle to understand why a good sunscreen is vital.
Here's our to break it down for you...
By Thomas Moore, science correspondent
June is supposed to be pleasantly mild and balmy. But this is the second scorcher of the summer already. So, what's going on?
It has a lot to do with the jet stream.
Normally, high altitude winds sweep eastwards across the UK - right now it's formed a huge wave from south to north.
That's sucked hot air from North Africa up to Europe.
And it's going nowhere fast, almost locked in place beneath what's called a heat dome.
High air pressure has formed a lid over the continent.
It squeezes down on the air closer to the surface, increasing temperatures鈥� and stops it escaping.
It's like a pressure cooker.
Dry soil issues
The southeast of the UK catches the edge of the high temperature zone.
In southern and central Europe, it's much hotter, with temperatures into the mid-40s.
That's 10 or more degrees hotter than normal for this time of year.
And the "hot blob" is only slowly moving east.
Normally, moisture evaporating from the soil would cool the air.
But it has been dry for so long that the ground is baked, and the heat is unrelenting.
Danger warnings
Climate change is making heatwaves in June much more likely.
According to the World Weather Attribution Service, before the industrial age the southeast of England could expect to have three consecutive days above 28C once every 50 years.
Now, it's one in every five years. So, a heatwave is 10 times more likely.
Those able to cool off in a lido or on a beach may wonder what all the fuss is about.
But for vulnerable people, these high temperatures are potentially life-threatening.
As I found out in a heat chamber a few years ago, even in healthy people the body's core temperature can quickly climb to levels that are akin to having a fever.
What about temperatures for the rest of the summer?
The Met Office's long-range forecast shows a high probability of above-normal temperatures through to September, particularly in the southeast of England.
There will be a lot of variability from week to week, but heat tends to build through July, the month that set the UK record of 40.3C in 2022.
The summer heat is something we will all have to get used to.
It's great to have time off work - if you're lucky enough - to enjoy the weather.
And according to a poll commissioned by Virgin Media O2, many Britons are willing to call in sick to catch the rays.
The survey suggests 41% of UK workers have admitted to pulling a sickie just so they can make the most of the sun.
This figure is even higher among 18-24-year-olds - six in 10.
It's expected to be even hotter in parts of the UK tomorrow...
It's Wimbledon's hottest opening day on record, according to the Met Office's provisional data.
A temperature of 29.7C has been recorded at nearby Kew Gardens, which is higher than the previous Wimbledon opening high of 29.3C.
The UKHSA and Met Office have said amber alerts now apply to the following areas until 9am on Wednesday:
The alert had initially covered London, the East Midlands, the South East and the East of England only, and this was in place until 6pm tomorrow.
An amber alert was previously issued for all regions in England on 19 June, and this was the first time it had been used since September 2023.
Early warning
Heat health alerts are co-developed by the UKHSA and the Met Office.
They provide an early warning system to the public and authorities when temperatures spike to possibly dangerous levels.
Alerts are colour-coded (yellow, amber and red) to reflect the level of expected impact (green means there is no alert).
The image below shows how the current alerts look when mapped out.

Scottish Lassie asked for a forecast for Scottish towns today, with temperatures rising everywhere.
Much of the attention is on the South East of England today because of the heat health alerts.
But that doesn't mean it's cold in Scotland, despite a much cooler start this morning (see our 7.51 post).
The Met Office map (see below) shows Edinburgh is set for 22C at 12pm, and Glasgow 21C.
Aberdeen should expect temperatures of 20C at midday, while Dundee can expect 23C - seemingly among the hottest places in Scotland today.
We'll bring you more updates from across the UK throughout the day.
Swimmers are cooling off at Sea Lanes Brighton on the south coast, where temperatures could rise to 28C.
Over in SW19 - where the tennis at Wimbledon begins today - crowds have been lying in wait for the gates to open.
And in Maidenhead, some early risers headed out on to the river for some morning exercise.
A range of guidance is available for people keen to shield their pets from the potential dangers of the current heatwave.
For starters, don't keep them in the car, where the heat can soar to dangerous temperatures in minutes - potentially causing animals irreversible organ damage or death.
The humidity is also a factor, according to the Humane Society Veterinary Medical Association.
Dr Barry Kellogg, from the group, explained: "Animals pant to evaporate moisture from their lungs, which takes heat away from their body.
"If the humidity is too high, they are unable to cool themselves and their temperature will AG百家乐在线官网rocket to dangerous levels - very quickly."
The organisation says taking a dog's temperature can help, and this should not exceed 40C.
If it does, here's what to do:
The Humane Society also advises pet owners to limit exercise on hot days, and points out fans are not as effective on animals as humans.
It suggests providing ample shade and water.
And, it says, a cooling body wrap, vest or mat can help pets - as can a cool bath if your dog does not find them stressful.
