The graphs are updated every 6 hours and are designed to give an indication of the likely weather conditions for astronomical observation.
Low wind speeds and high pressure favor a calmer atmosphere, facilitating the use of higher magnification eyepieces, which are well-suited for planetary observation.
Conversely, low pressure and windier conditions may favor a clearer but more turbulent atmosphere, potentially making the use of a low-powered eyepiece a better option.
