This July was the driest on record for some English regions and the driest for England overall since 1935, with just 35% of average rainfall.
That, coupled with continued dry forecasts, is expected to push some areas of the country to formally declare a drought after a meeting of the National Drought Group, which is due to begin on Friday morning.
Sky News said these could apply to several different regions, citing an unnamed source in the Department for Environment, Food and Rural Affairs. The government said no decisions had yet been taken.
Any declaration would be regional and would not automatically trigger specific government interventions. However, it could cause local water companies to enact new restrictions for households or businesses to preserve supplies.
Several water companies have already announced restrictions on water usage. A ban on hoses and sprinklers for South East Water customers comes into effect on Friday, and Thames Water, which supplies 15 million people around London, said it was also planning restrictions.
