🌤 Now in SU-820
🧑🏫 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.
❓ Frequently asked questions
What do you write in a school weather diary?
The date, morning and daytime temperature, phenomena (clear/cloudy/rain), wind and pressure. For younger students temperature and phenomena are enough, older students add wind in m/s, pressure and humidity. Ready values for SU-820 are already filled into the table above (28 days filled).
Where do I get the data if I missed a day or a month?
Past days in the table are filled with actual weather-station readings for SU-820. Previous months — via the ← arrow or the month list above the table, earlier ones — in the weather archive. Weather archive →
How do I print a blank template?
Click “Blank sheet (fill in by hand)” — a separate page opens with an empty table (dates and weekdays stay), with a “Print” button on it.

Schoolchildren keep it for science and geography classes, and so do gardeners and anglers. Data for SU-820 is filled in automatically from weather-station readings: past days always contain facts, not forecasts, so you can check your own records against the table.
