Islanders are being asked to use water sparingly, as reservoir levels remain below the ten-year average for this time of year, despite the recent rain.
Guernsey Water says the last 12 months have been exceptionally dry, with October rainfall 20% below the average.
Water levels subsequently dropped to 69% at end of last month - which is the lowest they have been all year.
Managing director, Steve Langlois says winter is usually the recharge period for them:
"Most people save money for a rainy day, well we save water for a sunny day.
That means of the winter period, when we refill our reservoir, is really important to us.
Normally we would expect the autumn rain to start and for levels to start to increase in October, but we haven’t seen that yet.
He added that small changes to everyday habits will aid the recovery of the island's water reserves:
We asked customers to use water wisely in the summer and we had a really good response, and I’d like to thank everyone that helped us out with that, but obviously, the focus is a bit different in the winter.
We’re asking Islanders to be more careful how to use water indoors now, in bathrooms and kitchens.
Around about 2/3s of water is used is in the bathroom, so that’s a really great place to start.
If you’ve got a dual flush, then use that and make sure everyone in the house knows how to do that.
Perhaps in the kitchen, if you got an eco setting on your dishwasher or washing machine, wait until it’s fully-loaded, and then use that setting.
You might even want to set a timer and use those between 11pm and 5am that would be more efficient and it’ll help save you money."
