If the weather feels extreme warmth throughout the day, how would you describe it?

Describing the weather as "hot" is appropriate when there is extreme warmth throughout the day. This term effectively captures the experience of elevated temperatures that lead to a feeling of heat, which is what one would typically associate with extreme warmth. The descriptor "hot" indicates a significant level of warmth that can impact comfort levels and outdoor activities, making it a precise choice for conveying the sensation of extreme heat.

Choosing other terms like "windy," "cold," or "sunny" would not accurately describe the sensation of experiencing extreme warmth. While "sunny" can relate to warm weather, it does not specifically imply the intensity of warmth that "hot" conveys. Hence, "hot" succinctly categorizes the overall feeling of warmth experienced throughout the day.
