Candles and heat: how to store them properly in summer?

Summer means sunshine, high temperatures...and sometimes a few minor problems for our everyday items. Candles, as pretty and fragrant as they may be, are no exception. They can melt, deform, or lose their fragrance if not stored correctly. Here are a few practical tips to protect your favorite candles during the hot season.

Why is heat a problem for candles?

Candles are made from waxes (vegetable, mineral, or animal) that start to soften as soon as the temperature exceeds 25°C. From 30–35°C, some waxes partially melt, which can lead to:

  • Deformation of the candle

  • Drips or leaking wax

  • Loss or alteration of fragrance

  • Off-center wick, making the candle hard to light or burn unevenly

1. Store them away from light and heat

Place your candles in a cool, dry, and shaded place. A cupboard, drawer, or sturdy cardboard box will do the trick. Avoid rooms exposed to the sun (like window sills) or that are too hot (like a conservatory or a parked car).

2. Cellar or pantry: good allies

If you have one, the cellar or pantry are ideal places to store your candles in summer. These rooms maintain a relatively stable and cool temperature, away from hot summer spikes.

3. Watch out for damp places

Even though coolness matters, avoid places that are too humid, as they could affect certain candles, especially those made from natural wax (like beeswax), which are sensitive to humidity and can develop a white layer called "bloom." This is a natural phenomenon but may affect the appearance.

4. For scented candles: keep them closed

Scented candles are often more sensitive to heat because essential oils or fragrances can evaporate or oxidize. It is recommended to:

  • Keep the lid on if the candle has one

  • Wrap them in parchment paper or plastic wrap

  • Avoid contact with open air to preserve the aromas

5. When traveling: take precautions

Bringing candles in your luggage for a summer getaway? Slip them into an insulated bag or between two items of clothing, away from direct heat sources. Never leave them in a car in full sun.

In summary:

Storing candles in summer is above all a matter of common sense: cool, darkness, and protection are the key words. By taking a few simple precautions, you’ll avoid the disappointment of finding your candles melted, deformed, or scentless. And you can continue to enjoy their gentle light and fragrance even under a blazing sun.
