Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as sleet, snow, hail and drizzle) will fall from the sky at a certain time.
This number shows the air temperature for the time period. You can see the temperature in Celsius or Fahrenheit by using the dropdown menu.
Feels like temperature considers other factors, such as wind speed and humidity. This gives you a better idea of how the temperature will actually feel at the time.
Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and lull.
Strong winds are shown in bold for speeds of 29 mph or more.
The arrow shows the direction the wind is blowing. The letters show the direction the wind is blowing from (on a standard 16-point compass).
The number represents the average wind speed expected at that time.
Visibility measures the distance at which an object can be clearly seen.
| VP (Very Poor) | Less than 1 km |
| P (Poor) | 1.1 km to 4 km |
| M (Medium) | 4.1 km to 10 km |
| G (Good) | 10.1 km to 20 km |
| VG (Very Good) | 20.1 km to 40 km |
| E (Excellent) | Greater than 40 km |
Humidity is the amount of water vapor in the air. If there is a lot of water vapour, the humidity will be high. The higher the percentage of humidity, the wetter it will feel outside.
UV exposure index and the protection required to help keep you safe:
No risk of UV - It’s safe to stay outside. Low - You can safely stay outside. Consider sunscreen in direct sunlight. Moderate - Take care during midday hours and do not spend too much time in the sun unprotected. Sunscreen advised. High - Seek shade during midday hours, cover up and wear sunscreen. Very high - Spend time in the shade between 11am and 3pm. Shirt, sunscreen and hat are essential. Extreme - Avoid being outside during midday hours. Shirt, sunscreen and hat essential.

UK long range weather forecast
A mixture of sunny spells and showers or longer periods of rain are expected at the start of October. Showers are likely to be heaviest and most frequent across the north and whilst southern and eastern areas may see some rain at times, these areas likely seeing the best of the drier conditions. Winds generally light, but strong in the north and along eastern coasts. Later in the period, we may see a shift towards drier and more settled weather. Some spells of wetter weather remain likely at times; these are most probable in the northwest but could possibly spread to other areas too. Temperatures likely to be close to average throughout or perhaps slightly above average by the end of the period.
Updated:
Confidence remains low through this period. Drier and more settled conditions are most likely to start, though some periods of wetter weather remain probable. Later in October, there is an increasing chance of unsettled conditions developing more widely across the UK for a time. Temperatures most likely to be near normal or slightly above normal.
