A rain gauge helps you to know exactly how much it is raining. This is good information to know for a number of reasons. You will be able to keep an eye on how much it is raining and whether this is normal for the time of year.

Some rain gauges are very complicated while others are very simple. You will need to understand how your unique rain gauge works so that you can read it accurately.


The most important thing is that you make sure the rain gauge is empty before you start recording the rain fall. If it already has some water inside then this will distort the readings. It's actually a good idea to empty the rain gauge every time you read it, reading it every day for example will help you to get into a routine.

Same Time

To get the most accurate results possible, you should take readings from your rain gauge at approximately the same time each day. Record all of the results in a book so that you can look at any trends.

Reading the Rain Gauge

When reading the gauge, lift it up to eye level. This will make sure that you are always reading the result accurately and don't accidentally make a mistake.
