Understanding the Role of Temperature, Humidity, and More

When it comes to enjoying your favourite candle, you might not realise how much the weather outside plays a part in the experience. Seasonal changes—particularly shifts in temperature and humidity—can significantly influence how well a candle performs in terms of fragrance throw, burn quality, and even storage longevity. For discerning UK candle lovers, understanding these effects can help you get the most out of your home fragrance, no matter the time of year.

Temperature: More Than Just a Number

Let’s start with temperature. Heat plays a pivotal role in how fragrance is released from a candle. Warmer temperatures in the summer soften waxes, especially those with a lower melting point like soy or coconut wax. This softening can cause candles to release fragrance more easily—even when not lit—resulting in a phenomenon known as a “cold throw.” While this might sound pleasant, it can actually lead to scent diffusion that exhausts the fragrance oils prematurely.

Conversely, during colder months, wax hardens, which can slightly restrict scent throw. You may find that it takes longer for your candle to warm up and begin releasing its full fragrance profile. To counter this, consider burning candles in smaller rooms during winter to maximise scent diffusion, or opt for candles with stronger base notes like amber, musk, or woods, which tend to perform better in cooler air.

Humidity: The Hidden Influencer

While often overlooked, humidity has a surprising influence on scent perception. High humidity, typical during spring and summer in the UK, can dampen our ability to detect certain aromatic compounds. This is because moisture in the air interferes with the way scent molecules travel. So even if your candle is performing well, your nose might not pick up the full intensity.

On the flip side, dry winter air can enhance scent diffusion but may alter the balance of certain fragrances. Citrus and floral notes, for instance, may appear sharper or more fleeting. To navigate this, it’s wise to rotate your candles seasonally, selecting richer, grounding scents for winter and lighter, more refreshing blends for summer.

Airflow and Ventilation: A Balancing Act

Alongside temperature and humidity, airflow also affects how we experience candle scents. In the colder seasons, UK homes tend to be more sealed up, which traps heat—and scent—more effectively. This can amplify your candle’s presence in a space but may also cause the air to feel heavy if not balanced with regular ventilation.

In contrast, open windows and fans during the warmer months can quickly dissipate scent, requiring either more potent candles or multiple smaller ones spaced throughout the home. Look for candles with higher fragrance loads or use strategic placement—such as near entryways or shared living spaces—for best results.

Storage Tips for All Seasons

Proper candle care ensures that you enjoy a consistent scent experience regardless of the season. Store candles in a cool, dark place during the summer to prevent sweating or fragrance degradation. In winter, keep them away from radiators or heat sources to avoid uneven melting or softening.

Also, always cover candles when not in use. This preserves the integrity of the wax and fragrance oils while protecting against dust and moisture, both of which can affect performance.


Scent Strategy: Choose with the Seasons in Mind

As you now know, candles aren’t just decorative items; they’re dynamic products that interact with their environment. From temperature swings to changes in humidity, every season presents a new challenge—and opportunity—for scent lovers.

By choosing candles formulated to perform under specific conditions, and by adjusting your usage habits slightly, you can create a consistent and enjoyable aromatic atmosphere in your home throughout the year.
