Our weather symbols tell you the weather conditions for any given hour in the day or night. This means that the symbol for 9am shows you what you will see from 9am to 10am.
Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as sleet, snow, hail or 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.

East of England weather forecast
Headline:
Cloudy, with outbreaks of rain.
This Evening and Tonight:
Staying cloudy with some areas of coastal mist and hill fog. Residual rain will tend to peter out this evening into occasional patchy light rain or drizzle, before reinvigorating from the southeast through the early hours. Minimum temperature 12 °C.
Wednesday:
Some patches of coastal low cloud, and mist likely. Otherwise, generally rather cloudy conditions prevailing with further showery rain at times. Perhaps brighter with showers to the southwest. Maximum temperature 20 °C.
Outlook for Thursday to Saturday:
Some patchy coastal low cloud and mist likely. Otherwise, often rather cloudy with showers at times, perhaps heavy and thundery. Some brighter, warmer spells as well.

UK long range weather forecast
The weather will be changeable, with daytime showers continuing across the UK on Sunday and possibly Monday. The heaviest showers and greatest risk of thunderstorms is expected across southern parts, while northern areas are more likely to see drier, more settled conditions developing for a time. Temperatures will be generally around or just a little above average. With winds tending to be light, it will feel warm in sunnier areas. As we head further into the following week, confidence lowers into the following week. On balance, a continuation of the showers in the south seems most likely, with the north continuing to see the best of any drier weather. Temperatures will probably remain a little above average.
Updated:
Similar weather conditions to those of the preceding few days are most likely to characterise this period to the end of May; a mixture of unsettled periods with rain and showers and settled interludes in-between. Through the first half of June, the chances of above and below average rainfall are evenly balanced. There is a slightly higher likelihood of above average temperatures compared with below average temperatures, such that the chance of hot spells, although still very small, is slightly higher than normal too.
