Why 1 1 month is colder than China?

Geographical location difference, climate type difference.

1. Geographical difference: China is located between 35-53 degrees north latitude, and most areas belong to temperate monsoon climate, while Spain is located between 36-47 degrees north latitude and belongs to temperate maritime climate, so it will be colder than China people.

2. Altitude difference: Spain is a plateau country, with high altitude in most areas, so the temperature is low, while China is a rugged country with higher temperature than Spain.
