What is the temperature going to be today: Predicting the heat.

Weather is an essential aspect of our lives. The temperature is one of the most crucial weather phenomena that we monitor every day. The question that lingers everyone’s mind every day is what the day’s temperature is going to be. Predicting weather is not an easy task. It involves a tremendous amount of scientific approaches, experienced meteorologists, and advanced technology. This article will delve into how meteorologists predict the temperature and provide you with a better understanding of what affects temperature changes.

What is Temperature?

Before we dive into the technicalities of temperature predictions, let’s define what temperature means. Temperature is the measurement of the heat present in an object or atmosphere. It is expressed in degrees Celsius (°C) or Fahrenheit (°F). It represents how hot or cold an object can be. Meteorologists use a thermometer to measure the temperature. It is usually measured in the shade as direct sunlight can affect the thermometer’s reading.

The Factors that Affect Temperature Changes

Several factors affect the fluctuation of temperature. The most significant factors affecting temperature are:

  • Latitude: The closer you are to the equator, the warmer the temperature tends to be, while the closer you are to the poles, the colder it tends to be.
  • Altitude: The higher the elevation, the colder the temperature gets.
  • Topography: The landscape and its features, such as mountains and valleys, can affect temperature change.
  • Climate: The climate in a region affects temperature change. Areas with a dry climate can have a different temperature than areas with a humid climate.
  • Ocean Currents: Currents can carry cold or warm water and air, affecting temperatures in adjacent regions.

The Science of Temperature Prediction

Temperature predictions are made after assessing several scientific approaches. These approaches involve a combination of computerized simulations, weather models and data, and satellite imagery. Model simulation plays a crucial role in predicting the temperature, and the numerical computer models utilize math equations to predict future weather by analyzing past conditions. Computerized models use information, such as pressure, wind patterns, and humidity, to predict temperature change.

The Tools Used to Predict Temperature

Modern meteorologists predominantly rely on technology to make temperature predictions. These tools include:

  • Radiosondes: Radiosondes are weather balloons equipped with sensors that measure temperature, pressure, humidity, and wind speed.
  • Thermometer: Thermometers are the most basic tool used to measure temperature. They come in different varieties.
  • Weather Radars: Radars help predict the temperature as they can detect the position and movement of precipitation.
  • Infra-red Cameras: Infra-red cameras detect and measure different types of radiation, including that which comes from the earth’s surface.
  • Satellites: Satellites allow for predicting temperature as they capture images of weather patterns, atmospheric conditions, and precipitation.

Temperature Climates Around the World

Tropical Climates (Tropical Rainforest and Tropical Savanna)

Tropical climates are characterized by high temperatures and high humidity. They are often associated with regions within 25 degrees of the equator, such as the Amazon and the Congo Basin. These regions generally have high rainfall throughout the year. Temperature levels are only mild for regular parts of the day, hitting an average of about 28-29°C.

Temperate Climates (Humid Subtropical, Oceanic, and Mediterranean)

In these climates, summers are usually hot and humid, and winters are mild with rainfall. These regions are typically located between 25 and 50 degrees of the equator, such as the UK, France and the west coast of the USA. In winter, temperatures rarely fall below 10-15°C while in the summer months, they average up to 30°C.

Continental Climates (Humid Continental and Subarctic)

These regions are associated with long, hot summers and cold winters accompanied by low humidity levels. Continental climates are mainly found in the mid-latitude regions of the world, such as central Europe and the north-eastern part of the USA. In the summer months, temperatures can average up to 30°C, however, winters can drop below -30°C.

Polar Climates (Tundra and Ice Cap)

Polar climates are typically associated with permanently freezing temperatures. These icy conditions occur within the poles and circumpolar regions. Temperatures never rise beyond freezing, with the average temperature falling below -10°C.

Common Questions and Answers About Temperature Prediction

  • Q: Can we predict temperature accurately?
  • A: Yes, we can predict temperature changes with high accuracy.

  • Q: How far in advance can we predict the temperature?
  • A: With the use of advanced technology, meteorologists can accurately predict the temperature for up to 10 days in advance, with varying degrees of accuracy.

  • Q: Are temperature predictions usually correct?
  • A: Meteorologists predict temperature changes with high accuracy, and the predictions are usually correct, sometimes with a margin of error.

  • Q: Why are forecasts sometimes incorrect?
  • A: Weather forecasting is not an exact science, and there can be unanticipated changes in weather patterns. For example, a slight shift in wind direction or temperature levels can affect the forecast.

  • Q: How can temperature prediction impact our daily lives?
  • A: Temperature prediction can affect our daily lives by influencing our choice of clothes, transport, and outdoor activities.


Temperature prediction provides valuable information that helps us plan our day better. Although it is not an exact science, it is achieved with a combination of predictive tools and scientific methods aimed at forecasting the weather. With the increased reliance on technology and advanced meteorological techniques, meteorologists’ predictions become more accurate every day.
