Some parts of the UK may see a hosepipe ban put in place amid reports of a heatwave, will Glasgow be affected?

More nice weather could be on the horizon for Glasgow amid rumours of another heatwave in August, following the record breaking temperatures in July.

The potential for more hot weather, and the lack of rainfall has forced water companies across the UK to issue hosepipe bans in order to conserve water.

So, will there be a hosepipe ban put in place for Glasgow?

What is the threshold for a heatwave in the UK?

The UK Met Office website states that for a heatwave to be declared a threshold must be met.

The UK heatwave threshold is described on the Met Office website as: “when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.”

The initial heatwave thresholds were calculated based on the 1981-2010 climatology of daily maximum temperature at the midpoint of the meteorological summer (15 July). In 2022, the Met Office updated the threshold.

The threshold for a heatwave temperature differs by county, with some areas in the southeast having a threshold of 28°C, while areas to the north and west have a threshold of 25°C.

What is a hosepipe ban?

A hosepipe ban restricts usage of water in outdoor activities like filling up swimming pools, watering plants and washing cars.

  • Watering a garden using a hosepipe  
  • Cleaning a private motor-vehicle using a hosepipe 
  • Watering plants on domestic or other non-commercial premises using a hosepipe 
  • Cleaning a private leisure boat using a hosepipe  
  • Filling or maintaining a domestic swimming or paddling pool 
  • Drawing water, using a hosepipe, for domestic recreational use 
  • Filling or maintaining a domestic pond using a hosepipe 
  • Filling or maintaining an ornamental fountain 

Is there a hosepipe ban in Glasgow?

While the country has seen record temperatures in recent weeks there are no plans for an immediate hosepipe ban in Glasgow or Scotland as a whole.

Scottish Water have said that there are no plans to apply restrictions such as hosepipe bans in Scotland, but have asked that people use water as efficiently as possible.

The main parts of the UK that a ban has been put in place are in the South of England for places like Isle of Wight, Kent and Sussex.
