Heat Index Calculator
Get the 'feels like' heat index from air temperature and humidity using the National Weather Service equation — the apparent temperature in °F and °C, plus its heat-risk category
Humidity Comfort Calculator
Turn temperature and relative humidity into a dew point and a plain-language comfort level, from dry to oppressive, so you know exactly how muggy and sticky the air feels
Sunrise & Sunset Calculator
Estimate day length, sunrise, and sunset in solar time from your latitude and the day of the year — see how the summer sun stretches daylight at your latitude

UV Index Calculator
Enter a UV index value for its WHO category and action band, with links to the official WHO and EPA guidance and the daily UV forecast
Heat & the Elements Museum
Wander an immersive museum of the sun, the heat, and the ways we keep cool — the blazing star at the centre of it all and the seasons it drives, the science of temperature, humidity, and heatwaves, the long human story of ice, shade, and air conditioning, and the deserts and scorching places of the world, each in its own gallery, so you can get to know the forces behind every sweltering day: how heat works, why it matters, and how we've learned to live with it and beat it.
