How much do you trust the weather forecast? It is easy to say weather forecasters get it wrong all the time, and moaning about the weather forecast is almost a national sport in the UK. But how reliable are our forecasts? The evidence indicates they do a pretty sterling job. The Met Office checks the accuracy of its forecasts and publishes its performance figures online. When it comes to maximum temperature more than 90% of the predictions are accurate to within two degrees for a 24-hour forecast. Predicting rainfall is trickier, because showers can be so localised, but nonetheless three-hourly predictions of sunshine or rain are accurate more than 70% of the time.

Statistics show that today’s three-day weather forecasts for the UK are more accurate that a one-day forecast was in 1980. Similarly, a recent study of Australian weather forecasts, published in the Quarterly Journal of the Royal Meteorological Society, showed that the accuracy of five to seven day forecasts was similar to a one-day forecast 50 years ago. In his blog, US weather forecaster Dan Satterfield suggests that people who moan that weather forecasts are always wrong may be basing their opinion on what forecasts were like decades ago – when they did get it wrong a lot of the time.

Or possibly they are checking poor forecasts: computer generated forecasts that use icons to illustrate the weather hour by hour are almost always going to disappoint. But choose your forecast with care and you can be confident which days are “umbrella days”.

В качестве пересказа можно взять следующее:

As a rule, you can rely on weather forecast. But it’s very difficult to predict the weather, that’s why you shouldn’t blame weathermen when the weather forecast disappoints you. Of course, it’s a big surprise when instead of heat we have drizzle or fog. People, who make weather forecast, do their best to help us, but it’s not their fault if the weather wants to trick us.

So, if you don’t trust weather forecast, you can always look out of the window and see if the weather is bad or it is going to change for the better. If you see that the sky is overcast, it’s better to take your umbrella, even if they promise a lot of sunshine.
