At 7:03 am, Salma al Habsi turns the bathroom tap to the blue “C” — cold. She waits. The pipe rattles, and then steaming water gushes out. Curious, she places a kitchen thermometer beneath the stream. The reading shocks her: 47°C.
“I can’t wash my face, and I can’t bathe my younger brother without mixing in chilled water from the fridge,” she says. “From May onward, the cold tap is hotter than my shower in January.”
Across Oman, the arrival of summer overturns one basic expectation — that cold water should flow from the tap. From Muscat to Sur, households are learning to adapt to a seasonal reality where “cold” often means hot, and sometimes dangerously so.
The reason sits silently atop thousands of homes: rooftop plastic water tanks, often holding between 1,000 and 2,000 litres, exposed to relentless desert heat.
“Most homes store municipal water in rooftop tanks,” explains Tamjid Hassan, a plumber in Al Amerat with over a decade of summer repair experience. “When temperatures outside touch 48°C, the tank surface can reach nearly 70°C. The water inside absorbs heat for hours.”
By midday, water flowing into homes can range between 45°C and 55°C, often hotter than a regular shower setting. Pipes running along exterior walls and ceilings intensify the problem before the water reaches taps.
For many families, daily routines now revolve around beating the heat.
In Al Seeb, housewife Sawsan al Ajmi has learned to adjust. “I once tried washing lettuce and it wilted instantly,” she says with a laugh. “Now I fill containers early in the morning and keep them indoors. That becomes our cold water for the day.”
For 68-year-old Shamsa al Musallami, mornings are the only safe window for chores. “Laundry, dishes, bathing — everything happens before 8 am,” she says. “After 10 am, both taps feel hot.”
Health experts warn that the issue is more than an inconvenience. Water temperatures of around 50°C can cause burns, especially among children and older people who may not expect hot water from a tap marked cold.
Parents are advised to test water temperatures before bathing children and to avoid assuming the blue tap is safe during the summer months.
As Oman’s summer intensifies, adapting to hot taps has become less of an inconvenience and more of a seasonal survival skill — one measured not in degrees outside, but in the temperature of the water flowing at home.
HOW FAMILIES COPE
Store water early: Fill containers before 8 am when tanks are coolest.
Shade rooftop tanks: Reflective paint or simple coverings can reduce heat build-up.
Test before use: During afternoon hours, assume both taps may run hot.
Mark taps: Some households even place red tape over “cold” taps to remind children.
