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.
Wales weather forecast
Headline:
A dry and sunny weekend
Today:
It will be a fresher start than recently but any early cloud will soon lift and clear to leave a day of long lived, warm and strong, sunshine. Maximum temperature 23 °C.
Tonight:
Staying dry this evening with plenty of late sunshine. Dry and clear overnight, feeling fresh by the morning away from the coast. Minimum temperature 4 °C.
Sunday:
Another day of long lived strong sunshine, feeling warm in the sunshine but still a little fresher at the cost in the breeze. Maximum temperature 23 °C.
Outlook for Monday to Wednesday:
Staying dry with high pressure remaining dominant. Plenty of strong sunshine but some cloud bubbling up at times. Warm days, albeit cool overnight with a slight breeze.
Updated:
UK long range weather forecast
High pressure is expected to dominate, with light winds for many, except perhaps along the English Channel where the winds could still be fresh at times. It should remain often sunny, but some cloud is likely at times, especially in eastern areas, and particularly during the mornings. It is expected to stay dry in most areas though, but the odd shower is possible, mainly over high ground in northern parts at first, and then later in more southern parts. Temperatures overall will be a couple of degrees above average, perhaps more so later, and it will feel warm or very warm in the sunshine away from any cloud and wind in the east. Later in the period, the risk of some thundery rain or showers in the south increases slowly.
Updated:
High pressure is likely to become less dominant with time, especially in the south with low pressure likely to approach from the near Continent. Northern areas may hang on to the largely dry conditions, but southern areas will see an increased risk of occasional heavy rain or thunderstorms from time to time. Any changes will be slow though, and there will still be plenty of dry and warm, sunny weather between any rain or thunderstorms, with temperatures widely above average, perhaps significantly so.
