Candles are a great way to create a cosy atmosphere, but they can be tricky to maintain, especially in the summer heat. The warm summer sun can cause havoc on candles, leading to fading and melting. While it may seem convenient to store candles in the refrigerator to prevent melting, this can actually cause the wax to crack and separate from the wick, making it unsafe to burn. So, what can be done to prevent candles from melting in the sun?
What to do about melting candles in the sun
| Characteristics | Values |
|---|---|
| Location | Keep candles in a cool, dry, shaded place, away from direct sunlight and heat sources such as windows, doors, vents, cars, and conservatories. |
| Storage | Store candles in a cupboard, in their box, or wrapped in foil or plastic wrap. Do not store candles in the refrigerator as this can cause the wax to crack and separate from the wick. |
| Containers | Use airtight containers to maintain temperature and prevent melting. Containers or jars can also protect candles from melting by acting as a barrier and insulating the wax. |
| Waxes | Choose candles made from waxes with a higher melting point, such as beeswax, stearic acid, or microcrystalline wax. Avoid coconut wax, soy wax, and essential oils as these are more sensitive to heat. |
| Wicks | Trim wicks to a quarter of an inch or 5mm before each use to prevent excessive flame size and heat output. |
| Lighting | Use alternative lighting options such as LED or battery-operated candles. Burn candles for shorter periods in hot weather, and only in the evenings when it is cooler. |
| Additives | Use additives such as Ultra Violet Light Absorbers (UVLA) or stearic acid to increase the melting point of the wax. |

Choose the right candle wax
When choosing the right candle wax, it is essential to consider factors such as scent throw, burn time, eco-friendliness, and aesthetic. Here are some popular types of candle wax and their unique characteristics:
Paraffin Wax
Paraffin wax is one of the most commonly used candle waxes due to its affordability and versatility. It is derived from the oil industry's byproducts, which makes it inexpensive and widely available. Paraffin wax holds fragrances and colours well, making it a popular choice for scented candles. It also has various melting points, allowing for the creation of different types of candles, from votives to pillars. However, it may not be the most eco-friendly option and tends to produce more soot than other types of wax.
Soy Wax
Soy wax is a sustainable and eco-friendly alternative to paraffin wax. It is made from soybeans and offers a slow and steady burn, making it a great value. While soy wax is more challenging to work with and doesn't hold fragrances as well as paraffin wax, it is known for its excellent heat resistance. Soy candles have a higher melting point and can withstand warmer temperatures without deforming, making them a good choice for warmer climates.
Beeswax
Beeswax is one of the oldest forms of candle wax, produced by bees during the honey-making process. It has a subtly sweet natural scent and a tougher, more solid nature. Beeswax candles also have a relatively high melting point, offering natural protection against heat and sun exposure. However, it is important to note that while beeswax is natural, it is not vegan.
Coconut Wax
Coconut wax is another sustainable option that is often used in premium candles. It is known for its aesthetic quality and ability to create a unique, natural scent. However, coconut wax tends to have a lower melting point, and candles made with this wax may melt at temperatures as low as 78 degrees Fahrenheit. Therefore, it may not be the best choice for warmer climates or places with direct sun exposure.
Rapeseed Wax
Rapeseed wax is a natural and sustainable option derived from rapeseed oil. It is vegan-friendly, burns cleanly with minimal soot production, and is an excellent choice for those concerned about their environmental impact. Rapeseed wax is also suitable for blending with other waxes to achieve the desired consistency.
When choosing the right candle wax, it is important to consider your specific needs and preferences. Factors such as scent, burn time, eco-friendliness, and aesthetic all play a role in selecting the perfect wax for your candle-making projects or purchasing decisions.

Store candles in a cool, dark place
Storing candles in a cool, dark place is one of the most effective ways to prevent them from melting in the summer. The ideal storage location should be a cool, dry place away from direct sunlight and other heat sources, such as windows, doors, or vents.
Indoors, bathrooms, basements, cupboards, or interior rooms away from direct sunlight are ideal for storing candles during hot weather. If you don't have access to a cool, dark place, consider a space with a consistent temperature. Avoid locations where the temperature fluctuates, as this can cause the wax to expand and contract, potentially damaging the wick or candle container.
When storing candles, it is also important to use protective containers or packaging materials. Containers made of sturdy glass or metal can provide an added layer of protection against melting by insulating the wax and slowing down the melting process. Candles can also be wrapped in materials that do not absorb heat, such as kitchen plastic wrap, and placed in a cardboard box to minimise the risk of melting during storage or transportation.
Additionally, it is worth noting that certain types of wax have higher melting points. Beeswax candles, for example, have a relatively high melting point and offer natural protection against heat and sun exposure. Soy wax is also known for its heat resistance and ability to withstand warmer temperatures without deforming.
By choosing the right storage location, using protective containers and packaging materials, and considering heat-resistant wax types, you can effectively prevent candles from melting in the sun and preserve their beauty and functionality during the summer months.

Use protective containers
If you want to protect your candles from melting in the sun, one of the most effective methods is to use protective containers. Opt for candles that are already housed in sturdy glass or metal containers that can withstand higher temperatures without deforming or cracking. The container acts as a barrier, insulating the wax and slowing down the melting process.
If you have pillar or taper candles, you can purchase separate protective containers to place them in. Look for containers made from materials that can handle higher temperatures, such as glass or metal. These containers will help regulate the temperature and slow down the rate of melting.
When storing candles, it is essential to use airtight containers. This helps to maintain a stable temperature and prevent melting by reducing the impact of external heat sources. If you're storing candles in a hot car, for example, place them inside a cooler or insulated bag to regulate the temperature.
Additionally, consider using Ultra Violet Light Absorbers (UVLAs) in your containers. These additives are like sunscreen for your candles, reducing the fading and degradation caused by sunlight. They are simple to use and can increase the shelf life of your candles, making them a valuable investment.
Finally, if you're selling candles outdoors, always provide a shaded area for your products and limit the number of candles displayed in direct sunlight. By using protective containers and following these additional tips, you can effectively prevent candle melting in warm weather.

Maintain wicks
Maintaining candle wicks is essential for extending the life of your candle, preventing smoke and soot, and ensuring an even burn without tunneling. Here are some tips to help you maintain your candle wicks effectively:
Trimming the Wick:
Regularly trimming the wick to a length of about a quarter of an inch before each burn is crucial. This helps prevent excessive flame size, reduces heat output, and minimizes soot buildup. A shorter wick produces a more controlled flame, reducing the likelihood of the surrounding wax melting. It is recommended to use a wick trimmer, which makes cutting candle wicks easier and prevents wick debris from falling into the wax.
Preventing Mushrooming:
Keep an eye out for "mushrooming," which is when you see a clump of sooty carbon buildup on the wick. When you notice mushrooming, extinguish the flame and trim off the unsightly mushroom cap.
Centering the Wick:
Ensure that the wick is properly centred in your candle to avoid wasting wax. Regularly check that the wick remains well-centred, and consider using a wick centralizer when filling the wax into your container to maintain stability.
Storing in a Cool, Dark Place:
Store your candles in a cool, dark place with a consistent temperature. Avoid direct sunlight and places with fluctuating temperatures, as this can cause the wax to expand and contract, affecting the wick and container. A cupboard, a shaded space, or even the box the candle came in are ideal storage spots.
Choosing the Right Location:
When using your candles, avoid placing them in direct sunlight or near heat sources such as windows, doors, or vents. Opt for cool, shaded areas with stable temperatures, such as bathrooms, basements, or interior rooms.
By following these wick maintenance tips, you can enhance your candle-burning experience, maximize the life of your candles, and reduce the risk of melting, even during hot weather.

Consider alternative lighting options
If you want to avoid your candles melting in the sun, it's best to keep them out of direct sunlight and instead opt for cool, shaded areas. However, if you're looking for an alternative to candles, there are several options to choose from that can provide similar lighting and fragrance benefits without the risk of melting.
One option is to use LED candles, battery-operated candles, or flameless candles. These alternatives offer the ambiance of real candles without the risk of melting or deformation. They are also cost-effective, as they don't require constant replacement like traditional candles. You can find these at various price points and retailers, including Amazon and West Elm.
Another option is to use a candle warmer, which can be placed inside or outside. These warmers melt scented candles from the bottom up, releasing the fragrance without the need for a flame. This method also preserves the wax, extending the life of your candles.
If you're looking for alternatives to provide fragrance without the need for flames, you can consider reed diffusers, room mists, or essential oil diffusers. Reed diffusers can last for several weeks or even months, depending on their size, and require minimal effort to set up and maintain. Essential oil diffusers offer the added benefit of acting as a humidifier during dry winter months, and they allow you to create your own fragrance blends.
For those who enjoy the ritual of lighting a candle, incense can be a good alternative. It offers a similar experience to lighting a candle, but without the open flame.
Finally, solar-powered, candle-imitating lights are another option. These lights can be charged during the day and used at night, providing both lighting and potential cost savings on your power bill.
