Summer heat does a number on disposable vapes. When it's hot, the e-liquid gets thinner, which means it wicks faster. That can make the flavor hit harder—some people love that intensity. But it also means the coil can get oversaturated, leading to gurgling or even leaking. On the flip side, if your device sits in a hot car, the vapor will taste flat and slightly burnt. The trade-off is simple: you get more intense flavor in warm weather, but you risk muted notes and potential leaks. Keep your device in the shade or your pocket, not on the dashboard.
