Solid start by Oliver Tarvet as we remain on serve in the first set.

He was breezing to a love hold on his first serve but Leandro Riedi fought back to deuce. Tarvet, though, dug in to fend off a potential break and hold.

He’s getting good support too from the crowd, who are occasionally glancing to the sky and willing the odd cloud floating by to provide some respite from the sun. Sadly they have been in short supply.

The first opportunity passes by as Sonay Kartal puts a forehand long and that is swiftly followed by another stray stroke from the Briton as Jelena Ostapenko gets back to deuce.

It’s taken Sonay Kartal a few games to settle but she’s finally on the board in set one.

A few brilliant shots in there, including a gorgeous forehand which prompted ‘oooohs’ from the crowd.

It’s still so hot here, though, in the heat that I feel like shouting ‘oooh’ every time there is a tiny breath of wind.

This is much better from Sonay Kartal.

The 23-year-old has settled and has two breaks points.

While us Brits get into a lather over the heat, it's easy to forget the world's leading stars are well used to playing in sticky conditions.

Melbourne can be scorching during the Australian Open, while New York gets incredibly humid during the US Open.

And, with outdoor tennis needing decent weather to function, most stops on the global tours are held in warm climates which have the capacity to encounter heatwaves.

So regulating body heat - staying hydrated with water and electrolytes, using ice towels - is something the players are well used to doing.

Sonay Kartal has come out fighting.

The Briton draws a cheer from the crowd when a disguised forehand nestles into the corner for 40-0.

Jelena Ostapenko responds by slamming a winner straight off Kartal's serve.

But Kartal does get the hold and is on the board.

The first change of the ends offers Sonay Kartal and Jelena Ostapenko the opportunity to get some much-needed shade.

Kartal has an ice towel around her neck and shoulders and is protected from the sun by an umbrella.

It's also a great opportunity to reset after a difficult opening three games.

Sonay Kartal and Jelena Ostapenko met earlier this month at Eastbourne with the Latvian winning 6-3 7-6 (7-2).

It's already looking ominous for Kartal against the 2017 French Open champion.

Ostapenko smashes a volley to earn another hold to 15.

After a nervy start, Sonay Kartal is starting to settle in and defends the first two break points with authority.

Jelena Ostapenko seals the break at the third time of asking, though, when Kartal is chasing a drop shot and returns wide.

Sonay Kartal has a huge task on her hands in trying to overcome 20th seed Jelena Ostapenko.

The Briton, in her first service game, is already defending three break points.

The team and I were debating last night whether it's better to be on court early or later with this heat.

Temperatures are already into the late 20's and that is set to continue throughout the day, hitting around 32C mid-day. And it doesn't let up throughout the evening, expectation is that it will still be around 28C at 21:00 BST.

Briton Sonay Kartal will be hoping to avoid those soaring temperatures as she features on Court 3 against Jelena Ostapenko now.

Jelena Ostapenko wraps up a pretty comfortable hold to 15 with a booming forehand winner.

Action is slowly starting to get under way across the Wimbledon grounds.

Sonay Kartal and Jelena Ostapenko are up and running on court three with the Latvian serving first.

If you want to keep tabs on all the British players at Wimbledon this year, it may need to be a multi-screen experience.

There are 23 Britons competing in the men's and women's singles at the All England Club - the most since 1984.

Seven of the British contingent have qualified directly through their world rankings, with players inside the top 100 guaranteed a spot.

It is only the second time this has happened since 2016.

United States-based college student Oliver Tarvet came through the qualifying tournament, while a further 15 players were handed wildcards.

With 14 singles players inside the top 200 - also the most since 1984 - British tennis looks far healthier than it has in previous years.

Everyone loves an underdog story and there’s none bigger from a British perspective here at Wimbledon than Oliver Tarvet.

The world number 719 came through qualifying to secure his place in the main draw - becoming the first male British qualifier for Wimbledon since Alexander Ward in 2017.

He’s got plenty of interest here with crowds gathered around Court 4 for his opener against fellow qualifier Leandro Riedi.

The brollies are up at Wimbledon but it’s for a very different reason than usual.

The green and purple signature umbrellas are being used by fans to get a bit of shade.

Those, along with fans, papers and anything that can be wafted to create a bit of a breeze are the go to accessories.

After I spotted the collection of Spanish bucket hats sat around laughing together, I approached Jorge, Luis, Jose, Eduardo and his son, also Eduardo.

"I think I know who you're here for, then?" I said. "Sinner!" came the collective reply, followed by more laughter.

Of course, they are here to see one man, Carlos Alcaraz. Do they think he'll win it again this year? "Of course" they again tell me in unison.

"We were here last year to watch him in the first round, so he has to win this year as well. Our motivation for queueing was to see him play on Centre Court on the opening day," says Jorge, who is from Madrid.

For most of them this is their third or fourth year of embracing the queue and they managed to get themselves in the top 140 - so a centre Court seat for Alcaraz will be theirs.

"It's an incredible experience, very unique, obviously, camping here just to get tennis tickets I think is something that you can only do here in Wimbledon," says Jorge.

"At the beginning, the first time I came, I thought it was crazy. Then I decided to do it thinking, ‘oh, my God, this is crazy’. And then since we did it, we can't stop. We love it because just you find people, I mean, you meet people from everywhere and it's just great experience. So we love it."

Plenty of familiar faces are back at the All England Club for this year's Wimbledon Championships, including Rufus the American Hawk.

Rufus, who is preparing for his 17th year on patrol at Wimbledon, is responsible for scaring away pigeons and keeping the courts pest-free.

In second place in this year's queue, but having to cover a fair bit more ground to get there than Vicki and Nigel in front of them, are Linda and her friend Aleta from Houston in the United States.

They also arrived on Friday having flown overnight, dumping their bags at their accommodation before rushing to the queue to make sure their long journey was rewarded with a Centre Court ticket.

"I did it last year and I was number five. If you're going to fly that far, you want to make sure you get a really wonderful ticket!" said Linda.

"I just thought it was so much fun [last year]. The day I got home to the United States, I booked my Airbnb for this year. One of our other teammates [from our tennis club] is here as well, they’re like 680th.

"This is, like, the most gentile festival you can ever come to. It makes you love England. Everyone is so polite. Everyone is so nice. You guys queue so well. Everybody's been so kind. I just fell in love with it when I came here, I was going to come by myself if nobody else could join me."

Aleta was able to join Linda, with this her first trip to Wimbledon - and anywhere in Europe for that matter.

"I'm loving it. I'm scared to fly. This is my first time on a long distance flight and I've always wanted to come to Europe. I like old things, and I got to see the tower of London and some history. The ticket is affordable to get in for the match too, compared to the US Open or other slams.

"Everybody's just civilised and it's just nice, it's just so great. We’ve met a lot of nice people in the queue and yeah I would definitely come back again."

From Glastonbury to Wimbledon, it has been a good few days for anyone in the tent business.

Plenty of happy campers have been patiently waiting for the first day of Wimbledon to get under way.
