![]() ![]() If setting your thermostat to somewhere in the 80s sounds too warm, then a good rule of thumb to follow is to turn your thermostat up 7 to 10 degrees from your normal setting for eight hours a day, so you can save up to 10% a year. It also suggests that the thermostat be set to 82 degrees Fahrenheit when sleeping and 85 degrees Fahrenheit when out of the house for maximum savings - recommendations that were met with scorn and disbelief on social media. Energy Star, a program of the US Environmental Protection Agency and the US Department of Energy, suggested that homes be kept at 78 degrees Fahrenheit when home during the day.

You can get ‘feels like’ temperatures on our five day forecast and on our Android and iPhone apps.For others, it might make more sense to turn the thermostat down during the daytime when they're at work. Using these facts we use a formula to adjust the air temperature based on our understanding of wind chill at lower temperatures, heat index at higher temperatures and a combination of the two in between. When humidity is high, the rate of evaporation and cooling is reduced, resulting in it feeling hotter than it actually is. This results in the cooling of the body as heat is carried away from it. When a human perspires, the water in their sweat evaporates. On warm days, wind chill becomes less significant. The exception to this rule, however, is when temperatures climb higher. On windy days the speed of moisture evaporation from your skin increases and serves to move heat away from your body, making it feel colder than it actually is. We calculate a ‘feels like’ temperature by taking into account the expected air temperature, relative humidity and the strength of the wind at around 5 feet off the ground (the typical height of a human face!), combined with our understanding of how heat is lost from the human body during cold and windy days. The ‘feels like’ temperature takes these factors into account and should allow users to make a better assessment of conditions outdoors.īut how do you actually calculate the ‘feels like’ temperature? Conversely on a humid day in summer it can feel uncomfortably hotter than the air temperatures would suggest on their own. It is our ‘feels like’ temperature that gives you a better idea about how the weather will actually feel when you step outdoors, where wind and humidity can make a big difference.įor example, in winter a strong wind can make you feel much colder than the measured temperature would indicate. The temperatures that you normally see on our website represent the temperature of the air, but this takes no account of how we actually experience the temperature. Have you ever stepped out of the house in the morning and thought, ‘I knew it would be cold, but perhaps not this cold!’ This article was updated on 17 March 2022 ![]()
