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:
Staying settled this week with further warm sunshine at times.
This Evening and Tonight:
Plenty of late evening sunshine at first. Skies turning increasingly cloudy from the east overnight, with perhaps clearer skies further west. Feeling chilly under the clearest skies though milder under the cloud and still rather breezy. Minimum temperature 5 °C.
Wednesday:
Much of the country will probably start off quite cloudy. Slowly brightening up with warm sunny spells breaking through by the afternoon. Staying cooler in places, especially in the breeze. Maximum temperature 21 °C.
Outlook for Thursday to Saturday:
Staying dry with high pressure remaining dominant. Plenty of strong sunshine but some cloud is likely at times, mainly during the mornings. Warm days, albeit cool overnight. Breezy at times.
Updated:
UK long range weather forecast
Settled conditions are likely to dominate throughout this period with plenty of dry and bright weather across the country, with the best of the sunshine expected across the west. Some low cloud is likely in eastern areas each day, but this will tend to burn back towards the North Sea coastline during the day. There is the very small risk of a shower in the south, and isolated patchy drizzle along eastern coasts. Temperatures will continue to be warmest towards the west, with an onshore wind making it feel cooler in eastern areas, especially the southeast where winds will be strongest. Towards the end of this period, the chance of showers in the south may start to increase. Further north, the generally fine pattern is likely to continue.
Updated:
Into the second half of June, there is an increasing risk of rain or showers, perhaps thundery, affecting southern parts, while northern areas are more likely to stay predominantly dry. Temperatures are likely to be near or above average for many, however, the east may continue to see suppressed temperatures at times with an onshore flow. This flow may reduce at times which would see a recovery in temperatures in the east. Overall, winds are likely to be lighter towards the north, and slightly stronger towards the south.
