nippy

A nippy day is one that's cool and chilly, often making you want to wear warm clothes.

When people say it's been a nippy morning, they usually mean it's been quite cold outside, but not freezing. This word is especially common when talking about the weather in spring or autumn, when it can be a bit unpredictable. Imagine walking out of your house and being hit with a blast of cool air - that's what a nippy day feels like! It's also often used to describe a temperature that's perfect for outdoor activities, but might not be suitable for everyone, especially those who aren't fond of cooler weather.
