Warmer temperatures can trigger the skin's oil glands to produce more sebum. Separately, high humidity reduces how efficiently sweat evaporates off the skin's surface, since the surrounding air is already saturated with moisture. The combination of more oil production and less sweat evaporation is what creates that heavier, shinier, "coated" feeling that shows up as soon as the weather turns warm and humid.
Sweat, sunscreen, heat, and humidity all combine in a way that can leave skin more prone to clogged pores and irritation than a workout in cooler weather does. A few adjustments before, during, and after exercise can keep summer workouts from taking a toll on your skin.
Warmer temperatures tend to increase oil production, while colder air can leave skin producing less oil and relying more heavily on whatever moisturizer is applied. That's why the same moisturizer that felt perfectly balanced in summer can suddenly feel inadequate once winter arrives, and vice versa — it's not the product that changed, it's what the skin needs from it.
