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). The blue behind the arrow represents the sea, and green is the land. If the arrow points from green to blue, the wind will be blowing from land to sea (‘offshore’). The number is the average wind speed.
Beware of offshore winds if you are using inflatables, paddle boards or kayaks, because 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 that the waves are going 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 or pointing away from land, the height of the waves on the beach is likely to be lower than the height of waves offshore.
Lifeguards can give you advice on waves if you’re planning to go into the water.

UK long range weather forecast
Some dry weather at first in parts of the north and east on Friday, but heavy rain and strong winds moving in from the west or southwest through the day. Some uncertainty in the details but the heaviest rain and strongest winds most likely affecting parts of the south and west. Thereafter, a predominantly unsettled pattern continues, with showers or longer spells of rain for many, although these interspersed with brief drier or brighter spells. By the second week of April, perhaps the greater chance of drier conditions will be across the north, albeit with some overnight frost. Further south, a higher likelihood of further wet weather at times. Overall, temperatures probably averaging out close to normal.
Updated:
A general trend to less unsettled conditions is likely into April, with rain-bearing weather systems more likely to affect southern areas from time to time. However, most areas are likely to see some spells of dry weather, with potentially frost and some fog overnight, this most likely in the north. A possibility of strong winds at times, with temperatures generally close to average for the time of year.
