🧑🏫 How to keep a weather diary
- Pick an observation time — the same every day, for example 8:00 and 14:00.
- Write down the temperature — from the thermometer outside or from our table (weather-station data).
- Note the phenomena — clear ☀️, cloudy ⛅, overcast ☁️, rain 🌧, thunderstorm ⛈, snow ❄️.
- Add wind and pressure — for younger students “light/strong” is enough, older students write m/s and mmHg.
- Sum up at the end of the month — the warmest and coldest day, how many days had precipitation. Check yourself against the weather archive.
