How do I look up historical weather for my destination to decide what clothes to pack in Luoyang?

[Direct conclusion] 【Look up the same period over the past three years in the meteorological service or a weather app and pack for the overnight low rather than the daytime high. Key points to keep in mind: 1. In Henan spring and autumn the day-night gap often exceeds 10°C, more in mountains, so layers beat one heavy coat.】 Method: A 7-day forecast is not enough; historical ranges show the real seasonal swing. 2. | Step | Detail | |---|---| | History | high/low range for the period | | Gap | whether a coat is needed | | Mountains | subtract another 3–5°C | | Layers | base + mid + windproof shell | ◆ Tip: always pack a windproof shell for mountain days. 3. We send a seasonal packing list before departure. 4. We sign formal contracts and issue proper receipts with full after-sales support; call for consultation and booking. Note: Double check the meeting time and meeting point one day before the trip.
