Is It Bad To Cycle In Hot Weather?

Cycling during the summer can be very enjoyable. There are many places to cycle in the summertime, and even if you don’t live near a large city, there are probably some places close by that you can cycle to. But what do you do when the weather is hot and you don’t want to overheat?

There is a lot of debate surrounding the effects of heat on cycling performance. Some people believe that it has a significant impact, while others claim that it doesn’t make much of a difference. The purpose of this article is to explore the research on this topic and provide a comprehensive overview of the current thinking.

Does Heat Affect Cycling Performance?

First, it’s important to understand the different ways that heat can affect cyclists. Temperature and humidity can both have an impact, and they can work together to create an extreme environment. Temperature is the most well-known factor, with hot weather known to cause problems for riders. High temperatures make it difficult for the body to cool down, which can lead to fatigue, dehydration, and even heat stroke.

Humidity also makes things difficult for cyclists, as it makes the air thicker and harder to breathe. This can cause problems such as dehydration, heat stroke, and even sunstroke. In some cases, the combination of high temperature and humidity can be so extreme that it becomes dangerous for cyclists to ride in those conditions.

Heat can have a significant impact on cycling performance. In general, the higher the temperature, the greater the impact on performance. This is because when it’s hot, our body has to work harder to cool itself down, which takes energy and can make us tired. The hotter it is, the more difficult it becomes to maintain a good level of performance.

This is particularly true for athletes who are not used to high temperatures. They may find that their muscles fatigue more quickly and they are not able to produce as much power as they would in cooler conditions. In addition, dehydration can be a big issue when cycling in the heat. You can lose up to 1 liter of fluid per hour during extreme heat, which can decrease your performance and lead to dangerous health complications.

How Hot Is Too Hot For Cycling?

When the weather is hot, cycling can be a great way to cool down. However, there is a limit to how hot it can be before it becomes dangerous to bike.

The National Weather Service has put together a chart that shows the “heat index” which is a measure of how hot it feels outside. When the heat index reaches 105 degrees, it is unsafe for people to do any type of physical activity outdoors. This includes cycling.

When the temperature outside rises, it’s important to be mindful of the risks associated with cycling in the heat. If you begin to feel overheated or dizzy while cycling, stop riding and find a shady spot to cool down. Drink plenty of fluids and wait until you feel better before continuing your ride.

How Do You Prevent Heat Stroke When Cycling?

Cycling heat stroke is a condition that can occur when someone cycles in hot weather. The body’s natural response to the heat is to sweat, but when the humidity is high, sweat does not evaporate as quickly, which can lead to heat exhaustion or even heat stroke. Symptoms include confusion, dizziness, headache, nausea, and vomiting.

Heat stroke is a life-threatening medical emergency that can occur when the body’s temperature rises to 106 degrees Fahrenheit (41 degrees Celsius). Anyone can suffer from heat stroke, but it’s especially dangerous for people who are elderly, have a chronic illness or are pregnant.

The best way to avoid heat stroke is to be aware of the signs and symptoms and take steps to cool down and treat it immediately if it occurs. Here are some tips to help you prevent heat stroke when cycling in hot weather:

  1. Drink plenty of fluids before, during, and after your ride. Dehydration is a major risk when cycling in the heat, so make sure you drink enough water or sports drinks to stay hydrated.
  2. Wear light-colored clothing to reflect the sun’s rays. Dark clothing will absorb the heat and can make you feel much hotter.
  3. Wear sunscreen to protect your skin from the sun’s harmful UV rays. A sunscreen with an SPF of 30 or higher is recommended.
  4. Take breaks every 30 minutes or so. Stop for a few minutes and drink some water, rest your legs, and take in airconditioning or humidity if available.
  5. Plan your route carefully. Try to avoid riding in the hottest part of the day, and take advantage of any shade that you can find.
  6. If you’re new to cycling, start by riding on flat surfaces for short distances. As you become more comfortable with cycling, gradually increase your distance and difficulty of the routes you ride.

How To Ride A Bike In Hot Humid Weather?

Cycling in hot humid weather can be a challenge. The high humidity makes it difficult to breathe, and the heat can make you feel exhausted.

One of the best ways to beat the heat is to wear cool clothing that dries quickly. Cycling clothes made of quick-drying materials, such as polyester or nylon, evaporate sweat quickly, which helps keep you cool and comfortable. They also wick moisture away from your skin, which prevents chafing and helps keep you dry.

Another good option for hot weather cycling is lightweight clothing. Clothing that is lightweight doesn’t trap heat, making it a better choice for rides in warm weather. You may also want to choose clothing in light colors, as these reflect sunlight and help keep you cooler than darker colors.

Tips For Cycling In Extreme Weather Conditions

There’s no doubt that cycling is a great way to get around, especially during the summer months. However, when the weather starts to take a turn for the worse, cycling in extreme weather conditions can be quite challenging – even dangerous. Here are some tips to help you stay safe while cycling in extreme weather conditions:

– Make sure your bike is properly tuned and in good working order before venturing out into bad weather.

– Always dress appropriately for the weather, wearing layers so you can adjust as needed. Be sure to wear a helmet and other safety gear too.

– Check the forecast before heading out, and avoid riding in dangerous conditions like blizzards or torrential downpours.

– Ride defensively, keeping an eye out for slippery surfaces and other potential hazards.

– Take it slow when cycling in bad weather – there’s no need to rush!


Cycling in hot weather can be a daunting task. It is important to take the necessary precautions to make sure you stay safe and comfortable while riding. In general, it is best to avoid cycling in the heat of the day, but if you must ride, be sure to drink plenty of fluids, wear sunscreen and a hat, and avoid wearing dark clothes. If you experience any symptoms of heat exhaustion or stroke, such as headache, nausea, dizziness, or vomiting, stop riding and seek medical attention.
