Our weather symbols tell you the weather conditions for any given hour in the day or night. This means that the symbol for 09:00 shows you what you will see from 09:00 to 10:00.
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.

South West England weather forecast
Headline:
Showers merging into heavy and persistent rain overnight.
This Evening and Tonight:
Turning very wet this evening with persistent and heavy rain developing widely across the region. This may give localised flooding overnight, most likely in eastern counties of the region. Chilly but staying frost free. Windy at times, especially on coasts. Minimum temperature 4 °C.
Monday:
A generally wet day with periods of heavy rain, and the chance of some localised flooding. Breezy at times and especially windy in Cornwall. Temperatures around average but feeling chilly. Maximum temperature 8 °C.
Outlook for Tuesday to Thursday:
Brightening up through Tuesday with sunny spells. Largely fine on Wednesday after frost and freezing fog clears. Becoming windier and milder on Thursday with some heavy rain. Chilly at first.
Updated:
UK long range weather forecast
A transition to milder, wetter and windier conditions is likely to have spread to most of the country by Friday. By this time the main chance of any snow becomes more restricted to high ground in the north. However, the change in conditions may take until the weekend to reach the far northeast with wintry showers remaining possible here. Thereafter, a continuation of generally unsettled conditions is most likely through mid-December with spells of heavy rain and strong winds for most areas at times. Temperatures are most likely to be around average though with some milder spells, more especially in the south. Colder interludes remain possible but likely shorter-lived than the current period and probably more restricted to the north.
Updated:
Conditions are most likely to be changeable through this period. Wetter and windier than average conditions are slightly more likely than normal, especially in the west and northwest. Temperatures are most likely to be near or above average overall, especially in the south and west. It is possible that there will be further colder interludes, but these likely to be short lived at first. Perhaps a greater chance of a longer cold spell late in the period.
