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.
The arrow shows the direction of the wind (up is north). If the arrow points from land to sea, the wind will be blowing out to sea (‘offshore’). The number is the average wind speed.
Beware of offshore winds if you are using inflatables, paddle boards or kayaks. These winds can blow you out to sea. Read more about how wind will affect you at the beach.
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 (Moderate) | 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.
This is the average height of the waves, 1-2 miles out to sea. The height of the waves can vary. The individual waves out to sea or at the beach can be higher than this number. If you are close to the water, keep an eye on the waves to stop you or your belongings being swept away.
Read more about calculating the expected height of the waves at the beach.
This is the average number of seconds between one wave and the next, 1-2 miles out to sea. A long wave period (more than 10 seconds) means the waves at the beach may be more powerful. Lifeguards can give you advice on waves if you’re planning to go into the water.
Read more about the period of waves.
The arrow shows the average direction of the waves 1-2 miles out to sea. It indicates how sheltered the beach will be from these waves. If the arrow points towards land, most of the waves’ power will reach the beach. If the arrow is parallel to or pointing away from land, the wave height is likely to be lower on the beach than it is offshore.
Lifeguards can give you advice on waves if you’re planning to go into the water.

UK long range weather forecast
A changeable pattern is expected through the end of September and into early October. While an initial spell of settled weather is possible, with the best of the conditions in the south-east, there is a chance of rainfall arriving into the south-west and spreading across southern areas of the UK, with more frequent rainfall also likely across the north-west. Any prolonged settled conditions are likely to deteriorate later into the period, general conditions becoming more changeable with a mixture of rain, showers and some strong winds, interspersed with some drier interludes. Temperatures are expected to be close to or slightly above average for the time of year for most and while there may be some mild overnight periods, some cold nights with early-morning fog patches are possible under clearer conditions.
Updated:
A mixture of spells of rain and showers, along with some more dry, settled periods, are likely until the middle of the month, the latter perhaps slightly favoured. However, there could be a trend towards more frequent unsettled conditions as the month continues, which could lead to southern areas being wetter than average for the time of year. Northern areas may see slightly less rainfall than usual though. It is expected that temperatures will generally be above average for October, but, during clearer spells in particular, some nights may feel chilly.
