Met office says good weather will continue with 25C sun this weekend (2024)

FAQs

Is the Met Office the most accurate weather forecast? ›

Our world-leading weather forecast accuracy is therefore essential to the safety of life but can also be relied upon to help you plan for everyday decisions such as what to wear, how to protect your property or when to travel.

We provide forecasts from a few hours ahead to projections more than a century into the future. The timescale of each forecast greatly determines the level of detail we can give.

Chance of precipitation

For example, a 70% chance of rain represents a 7 in 10 chance that precipitation will fall at some point during that period. Chance of precipitation represents how likely it is that rain (or other precipitation: sleet, snow, hail, drizzle etc.) will fall from the sky over a certain time period.

"High" A UV index reading of 6 to 7 means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed. Reduce time in the sun between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun-protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.

The Short Answer:

A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

According to ForecastWatch, the premier organization for evaluating the accuracy of weather forecasts, The Weather Company is more likely to be the most accurate across all geographic regions studied (U.S., Canada, Central America, South America, Europe, Africa, Middle East and Asia-Pacific) and time periods covered.

Even now five-day weather forecasts are about 90% accurate, but 10-day forecasts are more like 50%. Anything beyond that becomes speculative. The Met Office and others do now issue long-term forecasts, but these give probabilities rather than making exact predictions.

Three-day forecasts — shown in blue — have been pretty accurate since the 1980s, and have still gotten a lot better over time. Today the accuracy is around 97%.

AccuWeather gathers the best and most comprehensive weather data to deliver forecasts with Superior Accuracy. Forecasts are pinpointed for every location on Earth and extend further ahead than any other source.

The "25% chance of rain" means there's a 25% probability of rain at some point within the forecast area, which is not related to duration or intensity.

What does 55 chance of rain mean? ›

15-24% = slight chance of rain. 25-54% = chance of rain. 55-74% = rain likely. 75-100% = definite rain.

(2) If the forecaster expected a widespread area of precipitation with 100% coverage to approach, but he/she was only 40% certain that it would reach the forecast area, this would, as well, result in a "40% chance of rain" at any given location in the forecast area.

Abstract. Chile's northern Atacama Desert has been pointed out as one of the places on earth where the world's highest surface ultraviolet (UV) may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low total ozone column.

In general, scientists think 5 to 15 minutes -- up to 30 if you're dark-skinned -- is about right to get the most out of it without causing any health problems. You can stay out longer and get the same effect if you use sunscreen. Talk to your doctor about what's right for you.

The highest UV index ever recorded was a whopping 43.3. This incredibly high UV index was detected in 2003 at Bolivia's Licancabur volcano. Other areas in South America, like Peru, Chile, and Argentina, often experience UV indexes higher than 25, but this 43.3 UV index was record-breaking.

AccuWeather is recognized for its weather accuracy leadership in a new global report from ForecastWatch, a leading third-party weather forecast monitoring and assessment company.

Global models with worldwide weather forecasts

These models are all generally fairly accurate in predicting large scale patterns/features, but all will become less accurate through time. The ECMWF is generally considered to be the most accurate global model, with the US's GFS slightly behind.
