To predict, whether it’s going to rain shortly is a tricky affair. Despite all the latest technologies and computers, one can not predict rain with 100% accuracy. It’s very much likely that pattern of weather suddenly changes and all the former predictions go wrong.

However, there are several indicators in our daily life which can help us to predict whether is it going to rain or not? These predictions are very simple and anyone can observe it easily in surroundings. Indicators are not necessarily proven scientifically but are much effective and provided that one can judge them correctly. Let us learn about these indicators one by one.

Rainy Weather

Nature & Types Of Clouds

There are several different types of clouds depending upon nature. Some of them are as follows:

  • Very dark Clouds –  are huge in volume &  are a very clear indicator of instant rain.
  • Vertical clouds – known as Cumulonimbus clouds. If clouds in your area gradually increase vertically there every possibility that it will rain soon.
  • Snowflake type of clouds – scientifically known as Altocumulus clouds. If you observe clouds in shape of snowflakes it is a sign of upcoming rain in next two days or so, especially when clouds start stacking in shape of a tower.
  • Serpentine shaped clouds – technically known as Cirrus clouds. They normally appear high in the sky and can be an indicator that it will rain in next 48 hours.
  • Cloud clusters in shape of towers – also known as Cumulus Castellanos. These clouds are somewhat fluffy in nature and carry less amount of moisture. But they can assist other types of clouds to gather around. So, if you observe such clouds in your area, you may expect positively that it may rain later.

  • Low & thick clouds – technically known as Nimbostratus clouds. If this type of clouds appears in your area, it will turn the sky much black. This is a clear indication that it will be raining.
  • If Cirrus & Altocumulus types of clouds appear simultaneously it is an indication of rain in coming days. The combination of both clouds collectively is known as Cirrostratus clouds.

Temperature & Humidity

When temperature is high and simultaneously there is high number of vapors in the atmosphere, we feel very humid and hot. This type of weather is an indicator of upcoming rain. But it has a peculiar behavior as well. Clouds may gather in your area but suddenly carried away by strong winds and rain falls somewhere else rather than falling off in your area.

However, if you are an expert, you can predict that where it will rain, keeping in mind speed of the wind. Level of humidity can be observed very easily. The more you sweat, the more is the humidity. Or in other words the wetter you feel, more is the humidity. The chances of rain are probably high if atmosphere includes heavy density of humidity.


Wind Direction is also proved to be very much helpful in prediction of rain. In part of the world we’re living, if winds come from the east (during summer season), rain is imminent, whereas if it is winter season, winds coming from the western side will result in rain. But it will not be the same case if you move to some other part of the world.

You will learn it with experience and observations to predict rain with the help of wind direction. Winds flow from high-pressure area to low-pressure area and if it flows oversea it will gather very high volume of moisture, resulting in rain. That’s why you often observe wet strong winds before rain.

Color of Sky

If sky color suddenly turns reddish in the morning time, this is an indication of upcoming rain. During old times, people, especially mariners used this technique to predict rain in next day or so. The Reddish color of sky resulting in the rain is proved scientifically. Reddish color of sky is because of the reflection of sun-rays over the moisture-laden clouds which results in darker color.

However, this prediction can go wrong if you are on extreme poles of the globe, i.e. North or the South Pole. The reason is that the sun sets or rises after an interval of six months, resulting in darkness and light in the entire duration.

Animal Behavior

  • Normally birds stop flying and seek shelter 2-3 hours before it started raining.
  • Large animals such as cows tend to move closer to each other if it is going to rain.
  • Ants build steeper nest than the normal.

Joint Pain

People suffering from arthritis may feel more pain than normal in their joints about 48 to 72 hours before it rains because air pressure causes swelling of joints.

Natural Indicators

  • The dry grass is an indicator of strong winds that may result in rain.
  • Plants release waste in low pressure environment which smells like compost. If you breathe deeply in the open air and feel such odor you may predict that it’s going to rain.
  • The feel of wetness/dampness or humidity is also an indicator of upcoming rain.

Finally, it is all about how strong your experience and observation is. You can be a better predictor of rain if you have a strong sense of observation and analysis.
