Temperatures have remained around the low 20C's on Saturday after pushing 30C for much of last week.
Sunday is set to be another warm and sunny day with temperatures reaching 24C in some places and the good weather is set to continue until at least Wednesday.
There is a risk of a few scattered shows and thunderstorms in the southwest on Monday.
Following some confusion NI Water have moved to clarify misconceptions around the hosepipe ban.
"The hosepipe ban, for now, applies to domestic usage only. Business customers currently are not impacted as it is recognised they rely on water use for their livelihood and may already have water efficient systems in place eg, metering or water re-cycling systems," an NI Water spokesperson said.
"However, saying that, if any business can conserve water then please do so, every drop counts! We have already seen some businesses committing to turn off their sprinklers and only washing the windscreens, mirrors, lights and number plates of their vehicle fleets which is beneficial to the wider community.
Despite the many comments on how much rain we experience in Northern Ireland, we want to be clear that at the minute, we have plenty of untreated water (from previous rainfall stored in natural loughs and behind dams etc), the problem is the sheer amount of water people are using at the tap.
"Customers are using the water faster than we can treat it and get it into supply, please only use what you need to! We may be surrounded by water, but did you know that despite our planet being covered in water, only 1% of it is actually drinkable!"

The public are being asked to only use water if absolutely necessary.
"The hosepipe ban does not apply to the use of watering cans however, please consider that plants do not need watered every day or you could use some water saving crystals to retain the moisture or you could use the dish water from the sink! Consider putting hanging baskets etc into the shade for a day or two," the spokesperson said.
"Be water wise around peak times: 7 - 9am and 5 - 8pm are the peak times for showering and bathing. Please consider taking a shower instead of a bath. Please turn off the tap when you are brushing your teeth or shaving."
If the ban is ignored it could lead to a total loss of water supply for some households.
"We would hope that people will voluntarily work with us to reduce their water usage over the coming days. A loss of water supply for households is a completely avoidable situation, however, if people continue to use water at the current rate, the loss of supply could become a reality," the spokesperson said.
"Unnecessary use of water i.e. washing cars, watering lawns etc, is putting the water supply of your own household and that of your neighbours at risk.
"If everyone simply uses the water they actually need, there will be plenty for everyone. By following the simple guidelines, this will negate the need to prolong the hosepipe ban with associated penalties."
