9 Ways To Predict The Weather Without A Weather Forecast Or Personal Weather Station
Most of us rely on weather forecasts to tell us what the weather will be like. But by observing certain atmospheric conditions, nature, and even animal behavior, we can make a fairly good prediction without it.

You probably heard the stories of old people saying it is going to rain because "they can feel it in their bones." And also when your mother or aunt complained about the thousands of ants invading the house because "there is probably some rain on the way again."
They are actually all correct, and there is an explanation for it. It is possible to tell whether significant changes in weather, especially rainfall, is on its way.
By observing your surroundings, especially specific elements of the weather, nature, and even animal behavior, you will be able to get a very good idea of how the weather will change in your vicinity in the immediate feature.
The nine elements listed above can all be excellent indicators of changes in weather. You will be able to make a surprisingly accurate forecast of how the weather will change in the coming hours by observing them. We take a close look at each one.
1) Cloud Color
One of the most visible ways of telling how the weather will react is by observing the clouds. Knowing the different types of clouds will definitely help you make more accurate assessments, and its actually not as difficult as you may think. More on that shortly.
It is not just the different types of clouds that will determine the weather. By also observing their altitude and color, you will be able to get a good indication as to when to expect possible rainfall, as well as how heavy it may be.
As you know, clouds are nothing more than moist air that has risen high enough to cool down, causing condensation and small raindrops to form. The amount of raindrops/moisture present in a cloud has a direct effect on its color.
In general, the darker the cloud, the more moisture it contains. That is why rain-bearing clouds like cumulonimbus and nimbostratus clouds have a dark gray, sometimes almost a black base. This normally indicates imminent and heavy rains.
Very light-colored clouds, like cirrus clouds, normally indicate clear weather for the foreseeable future. If they form out of nowhere in an otherwise clear sky, it may indicate possible rain within 36 hours, but does not indicate any imminent rainfall, and they carry very little moisture themselves.
2) Cloud Height
The height of a cloud has two aspects to it that determine its behavior: The actual height of the cloud base (altitude) and its vertical extent.
Clouds with their bases high in the air (cirrus, cirrocumulus, and cirrostratus) are generally not associated with rain, whereas low-lying clouds are more commonly associated with rainfall. This is just a very rough indication, though.
A much clearer indication of how a cloud will behave is the extent of the cloud density. Clouds like cumulonimbus clouds with a low base in the troposphere but with a massive vertical buildup almost always indicate some kind substantial rainfall.
In contrast, very thin clouds (clouds with a small vertical extent) are normally very unlikely to result in rainfall by themselves.
The best way to make an accurate assessment of approaching weather is by looking at the cloud color, height, and density combined. This way, you will be able to get the most complete picture of what to expect.
3) Cloud Type
Being able to identify the different types of clouds and their characteristics will make it much easier to know how a cloud formation will affect you and potentially how much or how little rain you can expect.
Lets quickly run through the list of most important cloud types, from the ones potentially producing the most rainfall, down to those producing none.
These mid to low-lying dense cloud formations are synonymous with large-scale rainfall. They are characterized by their dark color and are so dense that they can completely block out the sun. Depending on the wind speed, they can produce persistent rainfall for sustained periods of time.
Although they have a fairly low-lying base, these clouds build up vertically to spectacular heights of up to 39 000 feet (12 000 meter). They are commonly referred to as thunderclouds and are associated with thunderstorms and very heavy rainfall.
Due to the huge vertical buildup in these cloud systems, they contain a lot of moisture, which can lead to downpours so heavy that flash flooding can occur. Although intense, the rainfall normally doesn't last very long and normally dissipates within 20 minutes.
These mid-level clouds are characterized by a large featureless blanket of clouds that can spread for thousands of square miles. (This is the cloud type that comes to mind when people talk about a typical dreary winters day).
Altostratus clouds are normally associated with widespread light rain. Although they don't normally produce heavy rainfall by themselves, they are often seen as precursors for nimbostratus clouds.
Probably the most well-known (and loved) clouds around the world are the cumulus clouds. These well-defined cotton-like clouds are low-level clouds that are normally an indication of pleasant and clear weather.
As already mentioned, these streaky white clouds are formed higher up in the atmosphere and are considered high-level clouds as a result. They contain mostly light ice crystals and don't pose any danger of rain themselves. They are, however, often seen as indicators that rain might be expected within 36 hours.
Obviously, there are many other cloud types and sub-categories of the clouds just mentioned. They all fall within the spectrum of the 5 cloud types mentioned in this section, though, so for the sake of this article, we don't need to go into further detail.
Being able to recognize the different clouds as they approach will help you to get a better picture of what to expect in the coming hours.
You can get more detailed information about the different types of clouds and their characteristics in this article.
Approaching rain is almost always preceded by an increase in humidity (the amount of moisture in the air). There are several ways you can detect an increase in humidity. You can find tell-tale signs on both your own body and in the environment around you:
- "Damp" Feeling: It's hard to explain, but we all know the damp sensation when the air contains a large amount of moisture. The moist, sweaty feeling on our skins is another dead giveaway.
- Changes In Hair Structure: You may start to notice that your normally smooth straight hair suddenly starts feeling a bit frizzy, which is a direct result of more moisture in the air.
There are some other less obvious indicators of a buildup of moisture in the air, but the three just mentioned are some of the most obvious and easily detectable ones.
5) Changes In Vegetation
Nature is sometimes the best possible indicator of changes in weather. The cones on pine trees automatically close to protect themselves when the air becomes moist.
The leaves of maple trees start curling. In areas with high humidity, the wood starts to swell and warp. Even smelling the flowers will help you to detect humidity. Normally the smell of flowers is more powerful as scents are much stronger in moist air.
Yes, you are reading this right. The smells in the air can give you a very good indication of approaching weather. I already touched on the strong smell of flowers and the typical "wet smell" that is associated with the rise in humidity preceding rainy weather.
There are further indicators, however, especially from nature, that present themselves in the form of strong scents that points to approaching rainy conditions:
- Ozone: That typical smell preceding rainy weather is the smell of ozone.
- "Compost" Smell: A smell very reminiscent of decaying compost is very evident in the air, which is a result of plants releasing their waste.
- Swam Gasses: If you happen to live near a swamp, you may become very aware of swamp gas that the low-pressure system allows to rise and drift with the wind. (These gasses have a smell very similar to rotten eggs, so unfortunately not a very pleasant experience.)
As you start becoming more aware of these smells associated with rainy weather on a regular bases, you can actually pick up indications of changes in weather conditions without even looking or going outside.
7) Wind (Or Lack Of It)
One of the strongest indicators of approaching rain is the picking up of wind or, a change in wind direction. There is a small catch, however.The wind direction that brings with it the rain-bearing clouds, depends completely on where on the planet you are located. It means you have to know which winds are associated with rain or bad weather in your region.
In an area in the Northern Hemisphere, the wind will blow in completely the opposite direction than in an area in the Southern Hemisphere. If you have been living in a town/city for some time, you will most probably be familiar with the wind direction associated with rainfall. (Or you can find out from neighbors or older people very familiar with the region.)
Similarly, a lack of airflow (wind) very often points to approaching rain. Especially in a normally windy area, if the wind suddenly dies down and everything becomes very still, it more often than none is literally the calm before the storm. This is a direct result of the low-pressure system that moves in and pushes the normal wind patterns out of an area.
8) Animal Behavior
The behavior of animals and insects that are out of the norm can also be a clear indication of rain or stormy weather. This is because all of them have senses far superior to humans or even some instrumentation.
Thousands of years of evolution helped them to develop these lifesaving senses. They are able to pick up atmospheric changes and act long before the actual weather arrives. Here are just a few examples of animals & their behavior you can watch out for:
- Bird Behavior: If you are living in an area with plenty of bird activity, you may already be familiar with this behavior. Very often, before rain or stormy weather arrives, bird activity dies down very quickly. As they are able to sense the approaching weather conditions long before we can, they seek shelter and stop flying around.
- Livestock Behavior: If you live on a farm or in a rural area, you may be surprised how even more "domesticated" animals like cattle are able to pick up on an approaching storm long before there is any physical evidence. Very often, before a rainstorm arrives, you will see a herd of cattle huddle together and lie down for protection in the middle of a field.
These are behaviors that have been well documented and proven over the years and are pretty reliable indicators of approaching bad weather.
Then off course, you get quite a few unsubstantiated claims, like frogs sounding louder before a storm, and dogs eating grass.
The point is, by paying attention to how the wildlife and even some domestic animals around you suddenly change behavior, you can be provided with valuable information about approaching changes in weather conditions.
9) Insect Behavior
Insects too, can give one a good indication of upcoming weather events. Here are a few examples of insects and their behavior you can watch out for:
- Ant Invasions: This probably one of the most well-known phenomena throughout the world. Many of you have experienced your homes being invaded with ants sometimes more than a day before heavy rains arrive.
- Noisy crickets: There is a reason you hear crickets on hot summer nights. These cold-blooded creatures' metabolism increase as heat rises, allowing them to chirp more often than usual during warm weather. As a result, an increase in cricket noises may point towards a rise in temperatures.
Like animals, you also get some unsubstantiated claims, like spiders coming down from their nets being an indicator of rainy weather.
So yes, you definitely will be able to make a fairly accurate forecast of what the atmospheric conditions will be like at your location within the coming hours. As discussed, you achieve this by looking at the cloud formations, smelling the air, observing animal behavior, paying attention to the wind, and assessing the humidity.
Even better. By taking all these elements and combining all the "data" you get from them and analyze them together, you should be able to form an even more accurate picture of how the weather will behave for sometimes up to 12 hours.
Will you be able to make an accurate 24-hour forecast? Probably not. Will you be able to make a 5-day forecast? Off-course not. (except if you have your own personal weather satellite orbiting the earth. Most home professional weather stations are not even able to forecast beyond 24 hours!)
But having the ability to judge how the weather conditions around you may change is a pretty handy skillset to have.
