If the arrow points towards land, most of the waves’ power will reach the beach. It indicates how sheltered the beach will be from these waves. The arrow shows the average direction that the waves are going 1-2 miles out to sea. Lifeguards can give you advice on waves if you’re planning to go into the water. A long wave period (more than 10 seconds) means the waves at the beach may be more powerful. This is the average number of seconds between one wave and the next, 1-2 miles out to sea. Read more about calculating the expected height of the waves at the beach. If you are close to the water, keep an eye on the waves to stop you or your belongings being swept away. The individual waves out to sea or at the beach can be higher than this number. This is the average height of the waves, 1-2 miles out to sea. 11 Extreme - Avoid being outside during midday hours. 8-10 Very high - Spend time in the shade between 11am and 3pm. 6-7 High - Seek shade during midday hours, cover up and wear sunscreen. 3-5 Moderate - Take care during midday hours and do not spend too much time in the sun unprotected. No risk of UV - It’s safe to stay outside.

UV exposure index and the protection required to help keep you safe: The higher the percentage of humidity, the wetter it will feel outside. If there is a lot of water vapour, the humidity will be high. Humidity is the amount of water vapor in the air. Visibility measures the distance at which an object can be clearly seen.

The number is the average wind speed.īeware of offshore winds if you are using inflatables, paddle boards or kayaks, because these winds can blow you out to sea. If the arrow points from green to blue, the wind will be blowing from land to sea (‘offshore’). The blue behind the arrow represents the sea, and green is the land. The arrow shows the direction of the wind (up is north). The number represents the average wind speed expected at that time. The letters show the direction the wind is blowing from (on a standard 16-point compass). The arrow shows the direction the wind is blowing. Strong winds are shown in bold for speeds of 29 mph or more. Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and lull. This gives you a better idea of how the temperature will actually feel at the time. You can see the temperature in Celsius or Fahrenheit by using the dropdown menu.įeels like temperature considers other factors, such as wind speed and humidity. This number shows the air temperature for the time period.

Magnitude 6.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.

The flight information is radioed to ground stations and relayed to meteorologists. One difference is that the loss of airplane data could continue into the summer, the European Centre said. That has led the European Centre to see 45% drop-off in incoming reports from airplanes since March 1. About 17% of all trips worldwide have been cancelled, according to FlightAware, an airline tracking service. The decrease in flights due to Covid-19 pandemic hasn’t been that severe so far. The European Centre for Medium-Range Weather Forecasts found between a 4% to 5% loss in its modeling abilities, Davis said. After the September 11 terror attacks in the US, the grounding of global air traffic caused a deterioration of computer weather models. Forecasters have faced this challenge before. There could be a resulting dip in weatherforecasting accuracy, meteorologists warn, but fortunately there are possible workarounds to augment the remaining flights.

With flights halted in many nations, meteorologists have seen a steep decline in more than 700,000 daily weather observations from aircraft. In terms of importance, aircraft data are usually in the top five, said Chris Davis, a scientist at the National Center for Atmospheric Research. That means a crucial eye in the sky has weakened just as spring flood waters rise across North American and Europe, and farmers are preparing to plant wheat, corn and soybeans. NEW DELHI: The pandemic that has idled scores of commercial flights is having a little-noticed consequence for meteorologists, whose forecasts rely in part on data collected from planes.
