Temperature values

The temperature value in white is the air temperature in your chosen units.

The temperature value in blue and surrounded by a blue dashed line is the feels like temperature which takes into account wind speed to give a more representative indication of how the temperature will feel. For example if the temperature is 0 C it will be much colder with a wind speed of 25mph than with a wind speed of 10 mph

e.g. air temperature 12°C, feels like 10°C would be displayed as follows:
12°C
10°C

Wind symbols

The number inside of the circle indicates the wind speed in your choosen units and the arrow points in the direction that the wind is blowing

e.g.
Wind
12 mph wind from the south
if your choosen wind speed units were mph this would indicate a mean speed of 12mph, coming from the south.

Solar UV symbols


The strength of the sun's ultraviolet (UV) radiation is expressed as a 'Solar UV Index', a system developed by the World Health Organization. These Met Office forecasts include the effects of:
  • the position of the sun in the sky;
  • forecast cloud cover;
  • ozone amounts in the stratosphere.

The solar index does not exceed 8 in the UK (8 is rare; 7 may occur on exceptional days, mostly in the two weeks around the summer solstice). Indices of 9 and 10 are common in the Mediterranean area.
