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.
East of England weather forecast
Headline:
Low cloud spreading inland tonight, sunshine Tuesday afternoon.
This Evening and Tonight:
The cloud will once again expand westwards to become widespread overnight. Turning cool under any clear spells at first but then a mild night for many under the cloud. Minimum temperature 8 °C.
Wednesday:
Cloudy to start, then cloud clearing back to the coast through the day. Low cloud perhaps less extensive than Tuesday in the afternoon, with more sunshine as a result. Warmer. Maximum temperature 23 °C.
Outlook for Thursday to Saturday:
Cloudy on Thursday morning but dry and becoming largely sunny. A good deal of sunshine on Friday. Some showers on Saturday, potentially heavy and thundery in places. Feeling muggy.
Updated:
UK long range weather forecast
Plenty of dry weather with a good deal of sunshine continuing for most. An area of showers likely moving in from the southwest. These possibly heavy and thundery at times, perhaps most likely across the south and west. This area likely to make progress northeasterly across much of the UK through the weekend but low confidence around exact details of this progression, plus the degree of activity. Temperatures generally widely very warm, locally hot, and becoming humid especially in the south and southeast. Winds generally light or moderate for most areas. Later, most likely plenty of fine and settled weather with sunny and clear conditions for many parts. Likely to be warmer than normal for much of the UK. Risk of showers, possibly heavy and thundery, especially in southern parts.
Updated:
More likely continuation of the fine and settled weather with a risk of showers through mid-July. High pressure re-orientate to lie near the southwest with low to the north. This brings a greater chance of rain to the west and northwest. Most likely temperatures trending back towards average or above. Very unlikely to be cooler than normal. · Low confidence in detail, as is often the case in summer.
