For a trip to San Angelo between November and March, when the average temperature ranges from 9°C to 17°C and nighttime minimums can drop to 3-5°C (especially in January), it is recommended to bring warmer clothing. The layering principle will be perfect here: t-shirts or long-sleeved tops, a sweater or fleece jacket over them, and definitely a warm jacket or coat, especially for evening walks and morning hours. Jeans or thick trousers will not be amiss. In transitional months, such as April and October, the weather is more moderate, but layering will also help adapt to temperature changes throughout the day – from a cool morning to a warm afternoon.
