Virgin Media O2 predicts network traffic drop during heatwave
June 27, 2025
As the UK readies for another spell of soaring temperatures, Virgin Media O2 is predicting network traffic to drop as Brits head outside to enjoy the sunshine.
Analysis of network traffic during the heatwave earlier this June shows that traffic dropped by over 7 per cent when the temperature hit 30°, as the nation clocked out of work to soak up the sun.
A nationally representative poll commissioned by Virgin Media O2 Business found that 41 per cent of UK workers admit to having called in sick to make the most of hot weather, with that figure soaring to 6-in-10 18–24 year-olds.
Forecasted highs of 35°C on June 30th have sent sun-lovers into planning mode, with the most popular heatwave activities including:
- Spending time in a park or garden – 77 per cent
- Taking a spontaneous trip to the beach or countryside – 65 per cent
- Eating out at a restaurant or café – 67 per cent
Suns out, laptops away: Network traffic slumps as Brits log off
The traffic dips have emerged from Virgin Media O2’s broadband network analysis, which is a reliable indicator of the connectivity habits of the British public. The data reveals a noticeable drop in traffic during the warmest weather, suggesting employees are stepping away from screens – whether officially on leave or not.
Gareth Lister, Director of Connectivity at Virgin Media O2, commented: “Whether they’re heading to the beach, the park or their back garden, our data shows people across the UK are making the most of the sunshine. Whatever the weather, and wherever people choose to work or unwind, we’ll be working to keep them connected.”
