An often unpredictable British summer seemed to grace south-west London with good weather on Tuesday as a variety of well-known individuals gathered for another day of Centre Court excitement at Wimbledon. 

After a weekend marked by sporadic rain and occasional sunny spells, the weather was kind to the newest group of celebrity spectators at the event. Among them were actress Sienna Miller, mezzo-soprano Katherine Jenkins, and former Chelsea and England football captain John Terry. 

Miller, 43, led the way in a vibrant floral patterned minidress as she arrived on the arm of partner Oli Green. 

Clearly anticipating the day’s events, the actress smiled brightly while entering the venue alongside Oli, who was equally sharp in a navy blue suit. 

Accompanied by filmmaker husband Andrew Levitas, Welsh singer Jenkins, 45, looked radiant in a pastel pink summer dress with a distinctive cinched waistline.

With a floral print and short-sleeve detail, the floor-length outfit ensured she stood out while mingling with fellow guests at SW19 on Tuesday. 

Joining his wife, Levitas, 47, looked appropriately dapper in a three-piece single-breasted suit and polished black dress shoes.

Elsewhere, retired footballer Terry, 44, opted for a smart casual blazer and jeans while attending the event alongside his rather more glamorous wife, Toni. 

The mother-of-two, 44, looked stunning in a white lace summer dress with a plunging neckline as she posed alongside her husband. 

Also in attendance, Mark Rylance was also dressed for the occasion in an olive green suit, off-set with a smart beige waistcoat and oxblood leather shoes. 

Completing the look with a raffish hat, the celebrated actor, 65, appeared to be in high spirits while posing for photos alongside artist and documentary photographer Lisa Barnard.  

Spectators and players alike should expect a torrid time at the south-west London venue over the coming week, after a yellow heat health alert was issued for the southern half of England, with temperatures once again set to soar.

The alert, issued by the UK Health Security Agency (UKHSA), will be in place for seven days from 10:00am on July 8 and covers London, the East Midlands, West Midlands, East of England, South East and South West.

“Significant impacts” are likely across health and social care services due to higher temperatures over the period, with the Met Office warning some areas will reach heatwave criteria and possibly see temperatures in the lows 30s by the end of the week.

It comes after two amber heat health alerts were issued in consecutive weeks at the end of June amid two separate heatwaves.

The UK saw its hottest day of the year so far when 34.7C was recorded at St James’s Park in central London on July 1, while the capital also experienced the hottest start to Wimbledon on record.

Provisional Met Office figures also showed England had its warmest June on record last month.

An official heatwave is recorded when areas reach a certain temperature for three consecutive days, with thresholds varying from 25C to 28C in different parts of the UK.
