What phrase describes warm weather?

The phrase that describes warm weather is "It's sunny." Sunny weather often accompanies warmth, as clear skies and sunshine typically indicate higher temperatures. When we think of warm weather, we often envision sunny days where the sun provides warmth and makes outdoor activities more enjoyable. While other weather conditions like wind can sometimes occur during warm weather, they do not inherently characterize it as "warm." Snow, on the other hand, is definitively associated with cold weather, ruling out those options as descriptors of warmth.
