A lighter concentration, such as eau de toilette or eau de cologne, generally suits hot climates better than a heavy parfum, since heat already intensifies projection and a lighter formula stops things tipping into overwhelming rather than pleasant.

Why Heat Changes the Equation

Warm skin releases fragrance molecules into the air far more readily than cool skin, meaning a concentration that feels perfectly balanced in a UK winter can feel much stronger and heavier in genuine heat. A lighter eau de toilette or a well-chosen perfume oil applied sparingly often gives a more comfortable, appropriately sized presence in hot weather than a full parfum would.

A Practical Approach

If you love a heavier concentration, you do not need to abandon it in summer, simply apply less than you would in cooler months, since the heat does much of the projecting work for you. Storing your bottle out of direct heat matters here too, since a fragrance left in a hot car or on a sunny windowsill will degrade faster regardless of how carefully you apply it. Our guide to perfume concentrations and seasonal fragrance guide both cover this, alongside our complete guide to perfume.
