Best Place To Put A Rain Gauge – Find The Optimal Spot

Last updated on February 23rd, 2023 at 06:54 am

It’s no secret that rain can come down quickly or at times not at all, which is why it’s important to have a rain gauge in the garden or yard. In this article, we will be going over the best place to put a rain gauge in your yard or garden.

I’ve been measuring rainfall here on my property since 2002 to get the best handle on wet and dry conditions. Sometimes it’s difficult to place a rain gauge in that optimal spot. I wanted to share my experience with what I discovered.

Getting accurate measurements from your rain gauge will be determined by the type of rain gauge, height off the ground, away from obstacles, and keeping the rain gauge level.

Before we dive into the nuts and bolts of location it’s important to mention the benefits of having a rain gauge at your home to start with.

Benefits Of Owning A Rain Gauge

For a start, a rain gauge can help you identify if your garden or yard is getting enough or too much water.

Both can be detrimental to the overall health and yield. Nothing can replace having exact rainfall totals at your location to make those determinations.

The official government weather instruments may be miles from your home and do not help you when it’s time to turn on sprinklers.

How many times has it poured at your office or school only to find that it did not rain at all when you returned home.

Factors To Consider For Accurate Rainfall

1. Type of Rain Gauges
2. Distance Off The Ground
3. Away From Obstructions
4. The Rain Gauge Stays Level

Let’s dig deeper into these factors.

Types of Home Rain Gauges

Analog Gauges

Each type of rain gauge collects rainfall data in a slightly different way. The two most common types of accurate reading are,

1) The standard analog rain gauge can be a funnel-shaped device that collects rainfall as it comes down through a funnel into an inner cylinder.

The funnel is usually made of glass or plastic, with a tapered design that allows for the gradual expansion of the funnel as it fills with more and more rain.

This funnel is connected to a graduated cylinder, and as the water collects, it rises in the cylinder, allowing you to measure precipitation.

This can be a very accurate rain gauge but must be emptied manually which can be time-consuming along with logging data.

Wireless Digital Rain Gauges

The wireless rain gauges are more set and forget it, they collect rain in a self-emptying bucket, once it starts to collect data it transmits information to a unit inside the home. They may provide ease of use as well as historical records stored in an app. This is handy for spotting trends.

Home solar powered weather stations are more affordable and most include wireless rain gauges.

Distance Off The Ground

One of the first things to consider when mounting your rain gauge for proper placement needs to be a minimum of two feet off the ground. Installing above the ground at the proper height will prevent rain from splashing up and inadvertently cause the gauge to measure rain inaccurately.

When mounting the weather station above the ground, you should pay particular attention that it will not tip over in high wind speed conditions.

A couple of methods for mounting a rain gauge to keep it off the ground are either on a pipe or possibly a fence post.

The first method of installing a pipe is to secure it in concrete so that a strong wind cannot tip the rain gauge to one side.

Often fence or deck post is more than adequate so long it’s in an open space, which will get into that shortly.

Stay Away from Obstructions

When deciding on a location, the next critical aspect is to put your gauge so that it’s free from obstructions.

Mounting too close to objects such as your roof, trees, or buildings can cause inaccurate readings from your rain gauge during heavy rain events.

Any obstacles that can cause water from entering the rain gauge are something you want to avoid.

Also, consider the future growth of trees or shrubberies that might not be obstructing now but might be after developing tree limbs in the future.

The ideal location would be at a corner of your garden, deck, or yard that is free from excessive wind and any obstacles that might interfere with a collection of rainwater.

The Rain Gauge Stays Level

Another aspect of installing your rain gauge that is often overlooked regardless of your install method is its level.

In both the funnel and the tipping bucket collection, it will give you inaccurate readings if it is not level.

Periodically it would be best to put a level on your rain gauge bucket to make sure it has not shifted.

In my first collection location, I discovered that it was pretty windy, so consequently, over time, it was causing my rain gauge to lean and not be level.

I started noticing collection totals dropping until I discovered the problem. Now every so often, I will go and make sure that it’s correct.

Conclusion

In this article, we have outlined the best place for a rain gauge in your yard or garden. The most common types of rain gauges are

1) standard analog rain gauge.

2) wireless rain gauges.

Both have their advantages and disadvantages. If using an analog rain gauge, it’s helpful to have a funnel-shaped device that collects rainfall as it comes down through a funnel connected to a graduated cylinder, because they allow you to get accurate data.

Having a properly functioning gauge gives you more information at your location rather than relying on government weather instruments miles away.

Other considerations for mounting your rain gauge are to keep it at least two feet off the ground so it is not obstructed by trees or buildings at a reasonable distance and free from excessive wind. Lastly, make sure it is level so there are no skewed data for accurate readings.
