Orchids are diverse and fascinating flowering plants known for their stunning beauty and unique features. However, unlike many other houseplants, orchids outside temperature requirements that must be met for them to thrive.

Orchids are sensitive to temperature fluctuations and require careful attention to their outside temperature to remain healthy and vibrant. Understanding these temperature needs is essential for any orchid enthusiast looking to cultivate these plants successfully.

What Is The Normal Orchid outside Temperature?

Orchids are a widespread and diverse family of flowering plants that require specific growing conditions to thrive, including the right temperature. Generally, the average orchid temperature ranges from 60°F to 80°F (15°C to 27°C) during the day and can dip slightly at night, but it should not fall below 55°F (13°C) or exceed 90°F (32°C) for an extended period.

It’s important to note that different orchid species have specific temperature preferences, and growers should consider their orchids’ natural habitat when determining the appropriate temperature range. Some orchids prefer cooler temperatures, while others thrive in warmer conditions.

Additionally, orchids require a slight temperature drop at night to mimic their natural environment and promote healthy growth and flowering. This drop in temperature can be achieved by keeping the orchids in a slightly more excellent location or reducing the temperature in the growing area at night.

Maintaining the proper orchids outside temperature for your orchids can be essential to their health and growth. You can help your orchids thrive and produce beautiful blooms by providing the ideal temperature range and monitoring them consistently.

How Can Orchids Be Kept At A Good Temperatur?

Orchids are beautiful, delicate flowers that require proper care and attention. One of the essential factors in caring for orchids is maintaining the right temperature.

Choose A Suitable Location

Orchids thrive in environments with consistent orchids outside temperature and humidity. Therefore, choosing a location that provides optimal growing conditions is essential. Ideally, place your orchids in a well-ventilated room that receives ample natural light but avoids direct sunlight.

Use a Thermometer

Monitoring the temperature is crucial in ensuring your orchids are thriving. Consider using a thermometer to track the temperature in your growing area. This way, you can quickly identify any significant temperature changes and take the necessary measures to regulate them.

Adjust the Temperature

Orchids outside temperature changes, so it’s essential to maintain a consistent temperature. If the temperature is too high, consider turning on an air conditioner or fan to cool down the room. Conversely, if the temperature is too low, use a space heater or heat mat to warm the area.

Consider the Season

The temperature requirements for orchids vary depending on the season. During the summer, you may need a fan or air conditioner to keep the temperature within the ideal range. In winter, you may need a space heater to provide adequate warmth.

Maintaining a consistent temperature is essential to keep your orchids healthy and thriving. By following the tips above, you can ensure your orchids receive the optimal growing conditions they need to thrive.

Determining the best orchids outside temperature for your location requires considering several factors, such as your geographical location, the season, and the type of orchid you are growingHowever, specific types of orchids may require different temperature ranges.

Here are some guidelines to help you determine the best orchid temperature for your location:

Check your hardiness zone

Your hardiness zone is a geographic area that determines the average minimum temperature in your region. Knowing your hardiness zone can help you decide which orchids suit your site and their required temperature range. You can check your hardiness zone online or consult with a local nursery or garden center.

Consider the season 

Orchids have different temperature requirements depending on the season. For example, in the summer, you may need to provide more ventilation or use a fan to keep the temperature within the optimal range. In winter, you may need a space heater to provide adequate warmth.

Know your orchid type

Different orchid types have additional temperature requirements. For instance, some orchids, such as Phalaenopsis, prefer slightly cooler temperatures, while others, like Oncidium, thrive in warmer temperatures.

Monitor the Temperature

Using a thermometer to monitor the temperature in your growing area is crucial in maintaining the best temperature for your orchids. Keep track of the temperature and adjust as needed to ensure your orchids remain in the ideal range.

The best orchid temperature for your location depends on several factors, including your hardiness zone, the season, and the type of orchid you are growing. By considering these factors and monitoring the temperature, you can provide optimal growing conditions for your orchids and help them thrive.

Frequently Asked The Question 

How cold is too cold for orchids?

Orchids are typically tropical plants that thrive in warm and humid environments. Therefore, they cannot tolerate shallow temperatures, and their ideal temperature range varies depending on the species.

In general, most orchids cannot withstand temperatures below 50°F (10°C) for an extended period, and temperatures below 40°F (4°C) can cause damage or death to the plants. Some cold-hardy orchid species, such as Cymbidiums and Odontoglossums, can tolerate slightly lower temperatures, but it is still essential to protect them from freezing.

Can orchids tolerate 40-degree weather?

Most orchids cannot tolerate 40-degree weather, as they generally adapt to warm and humid tropical climates. Sudden temperature changes or extreme temperatures can harm or kill orchids. However, some orchid species are more tolerant of cooler temperatures, and with proper acclimation and care, they may survive brief exposure to 40-degree weather.

Can orchids be left outside?

Whether orchids can be left outside depends on the specific type of orchid and the climate conditions in the area. Some orchids, such as Cymbidium and Dendrobium, can thrive outdoors in mild to warm climates.

However, other orchids, like Phalaenopsis and Paphiopedilum, are more delicate and require specific conditions, such as consistent temperatures and humidity levels, which may not be present in outdoor environments. It’s best to research the specific needs of your orchid and consult with a local horticulturist before deciding whether to keep your orchid outside.


Maintaining the correct temperature is crucial for the health and growth of your orchids. Whether you’re growing orchids indoors or outdoors, it’s essential to provide the optimal temperature range to ensure their well-being. 

When growing orchids outside, it’s essential to consider the weather conditions in your area and take measures to protect your plants from extreme temperatures, such as frost or heatwaves.
