Choose candles with high melting points, e.g. beeswax or soy wax
Choosing candles with high melting points is an effective way to prevent them from melting in the sun. While most candles are made from wax, which has a relatively low melting point, some waxes have higher melting points that can withstand warmer temperatures.
Beeswax candles, for example, have a naturally high melting point and offer excellent protection against heat and sun exposure. They are composed of complex esters produced by bees, which gives them a higher melting temperature without requiring additional processing. Beeswax is also biodegradable, eco-friendly, and produces less smoke when burnt, making it a sustainable option.
Soy wax is another popular choice for candles with high melting points. It is known for its excellent heat resistance and ability to maintain its shape in warmer temperatures. Soy wax candles often have higher melting points than those made with paraffin wax. Additionally, soy wax is a natural option, as it is made from hydrogenated soybean oil, and it can be blended with coconut wax to create a more sustainable candle.
When selecting candles, opt for those specifically designed for outdoor or warm-weather settings. These candles are formulated with higher melting points and are more resistant to heat and melting. Proper wick maintenance is also crucial for reducing the risk of melting. Trimming the wick to a quarter of an inch before each use helps control the flame size, generating less heat and reducing the likelihood of the wax melting.
By choosing candles with high melting points, such as those made from beeswax or soy wax, and maintaining proper wick care, you can enjoy your candles without worrying about them melting in the sun.

Store candles in cool, dry, shaded areas, away from direct sunlight
Candles are often made from wax, which has a relatively low melting point. During hot weather, the ambient temperature can exceed this melting point, causing the wax to soften and lose its shape. Direct sunlight exacerbates this effect, leading to significant melting and deformation of candles. Therefore, it is important to store candles in cool, dry, shaded areas, away from direct sunlight.
When storing candles, it is best to choose a location with stable and moderate temperatures. Indoor areas such as bathrooms, basements, or interior rooms away from direct sunlight are ideal for preserving candles during hot weather. A cupboard or shaded space is also a good option. It is important to avoid placing candles in sunny spots or areas with fluctuating temperatures, as this can cause the wax to expand and contract, affecting the candle's integrity.
If you must store candles outdoors, opt for shaded areas such as covered patios or screened-in porches to minimise sunlight exposure. Using airtight containers or wrapping candles in materials that do not absorb heat can also help maintain stable temperatures and prevent melting. Some people consider storing candles in the refrigerator during hot weather. However, this is not recommended as it can cause the wax to crack and separate from the wick, making it unsafe to burn.
Additionally, when displaying candles, it is best to avoid placing them in direct sunlight or near heat sources such as windows, doors, or vents. Instead, choose locations that are reasonable for the weather conditions, allowing you to enjoy the scent of the candle without lighting it, which is known as the "cold throw". Overall, by storing and displaying candles in cool, dry, shaded areas, you can effectively prevent melting and deformation caused by direct sunlight.

Use candles in sturdy containers that can withstand high temperatures
Candles are often made from wax, which has a relatively low melting point. As such, they are prone to melting in hot weather, especially when exposed to direct sunlight or placed near heat sources such as radiators or air vents. To prevent this, it is recommended to opt for candles housed in sturdy containers that can withstand high temperatures.
Containers act as a protective barrier, insulating the wax and slowing down its melting rate. When selecting candles for warm weather, consider options specifically designed for outdoor use, as these typically feature robust containers that are more resistant to heat. Glass or metal containers are ideal, as they can withstand higher temperatures without deforming or cracking.
For example, if you plan to use candles outdoors, choose those in sturdy containers that can be placed in shaded areas like covered patios or screened-in porches to minimise direct sun exposure. Additionally, consider the type of wax used in your candles. Some waxes, like soy wax and beeswax, have higher melting points than others, such as paraffin wax. Choosing candles made from waxes with higher melting points can help prevent melting in hot weather.
Proper wick maintenance is also important. Trimming the wick to a quarter of an inch before each use helps prevent excessive flame size and heat output. A shorter wick produces a more controlled flame, reducing the heat generated and the likelihood of the wax melting.
Finally, in extreme heat conditions, consider alternative lighting options like LED or battery-operated candles. These can provide the desired ambiance without the risk of melting or deforming your traditional candles. Remember, choosing candles in sturdy containers designed for high temperatures, combined with strategic placement and wick maintenance, can help you enjoy your candles even during the hottest months.

Maintain wicks by trimming them to a quarter of an inch before each use
Maintaining your candle's wick is an essential step in ensuring optimal candle performance and reducing the risk of melting. Before lighting your candle, inspect the wick and trim it down to a quarter of an inch in length. This simple act of wick maintenance helps to control the size of the flame, reducing the heat output and, consequently, decreasing the likelihood of the surrounding wax melting.
A longer wick can result in an excessive flame size, producing more heat and increasing the chances of the wax melting. By keeping the wick trimmed, you promote a more controlled and stable flame, which is especially important during hot weather when the ambient temperatures can already be close to or exceed the melting point of the wax.
Trimming the wick also offers benefits beyond reducing the risk of melting. It helps to prevent the wick from becoming too hot, which can cause the wick to bend and affect the quality of the burn. Additionally, a well-trimmed wick can reduce the amount of smoke produced by the candle, creating a more pleasant burning experience.
To trim your candle wick, use dedicated wick trimmers or scissors. It is recommended to trim the wick when the wax is solid and before each use. This practice ensures that the wick is the optimal length for a controlled burn, reducing the negative impacts of excessive heat on both the candle and your surroundings.
By combining proper wick maintenance with strategic candle placement in cool and shaded areas, you can further decrease the chances of your candles melting in the sun.
