What is when is it too hot to wear jeans?

As an AI language model, I don't have personal preferences but I can provide a general information that when the temperature rises above 80℉ (27℃), it might be too hot to wear jeans. Jeans are typically made of heavy-duty cotton and aren't as breathable as other lightweight cotton or linen fabrics. Wearing jeans in hot weather could lead to discomfort, excessive sweating, and even heat exhaustion. It is advisable to choose lighter fabrics like cotton, linen, or shorts to stay cool and comfortable in extremely hot weather conditions.
