Accepted Answer

Our weather forecast data is sourced from professional meteorological services with short-term (1-3 days) accuracy exceeding 90%.

Question 4

What is feels-like temperature?

Accepted Answer

Feels-like temperature is the temperature that your body actually perceives, taking into account air temperature, humidity, wind speed, and other factors. For example, in hot and humid conditions, it feels hotter than the actual temperature, while in windy and cold conditions, it feels colder.

Question 5

What is UV Index?

Accepted Answer

UV Index (UVI) is an international standard measuring the strength of sun's ultraviolet radiation, typically ranging from 0-11+. Index 0-2 is low, 3-5 moderate, 6-7 high, 8-10 very high, and 11+ extreme. When the index is high, apply sunscreen, wear sunglasses and a hat.

Question 6

Why do different platforms show different temperatures?

Accepted Answer

Different weather platforms may use different data sources, weather stations, or update times, resulting in slight temperature variations. Generally, differences within 1-2°C are normal. Our data is updated every 5 minutes to ensure you get the latest information.

Question 7

How accurate is the 7-day forecast?

Accepted Answer

Forecast accuracy decreases over time: 1-3 days has high accuracy (90%+), 4-5 days has moderate reference value, 6-7 days should be used for trend reference only. We recommend reconfirming the latest forecast 1-2 days before important plans.
