Yorkshire Water is urging people to use water wisely as the region basks in tropical temperatures.
The water company says that reservoirs are only 75% full after one of the driest Mays on record, with no rain expected until June.
There has been a spike in demand and Yorkshire Water is wanting customers to help it maintain its water stocks by taking measures like having a four-minute shower instead of running a full bath.
But the company insists there will not be a hosepipe ban this summer.
A Yorkshire Water spokesperson said: "We’ve all been enjoying the lovely weather over the past few months and it’s definitely helped boost everyone’s morale during what is a really difficult time.
"However, this good weather has meant we haven’t had much rain over the past few months and the levels of water in our reservoirs are lower than they normally would be."
Water Saving Tips from Yorkshire Water
Turning off the tap when brushing your teeth
Have 4-minute showers instead of baths
Fill your watering can while the shower is warming up
We’re also seeing people use more water than they normally would. Life is very different at the moment and we’re spending more time at home and in our gardens watering plants, filling paddling pools and pressure washing outside areas. "We have a team of experts who have the ability to move water around our underground grid network to help us keep taps flowing but we need our customers to play their part too."
