The NMC's 08:00 October 17 forecast gives cloudy weather and 32–23°C today, highs of 31°C and 30°C on October 18–19, light rain on October 20 and sharper cooling on October 21. Use mornings and evenings for outdoor walking, hydrate and pack layers for rain and temperature change.
Heat precautions still matter October 17–19
October 17 is cloudy at 32–23°C, followed by cloudy 31–20°C on the 18th and cloudy-to-overcast 30–20°C on the 19th. Autumn does not remove heat load from queues, plaza walking and carrying ceramics.
Use morning and evening for outdoor markets and districts, with midday indoors for exhibitions, food or rest. Carry water, sun protection and breathable clothing; older adults, children and long-haul arrivals need seated breaks every 60–90 minutes.
Rain and cooling change the pace from October 20
The forecast gives light rain and 28–18°C on October 20, overcast 21–15°C on the 21st and cloudy 24–16°C on the 22nd. Keep rural drives, stone lanes and outdoor photography cancellable, and pack compact rainwear, non-slip shoes and layers.
Add an outer waterproof layer to ceramic cartons without trapping wet plastic against the work. Check separate nowcasts for Sanbao, Fuliang, Yaoli and intercity routes; downtown weather does not establish mountain-road conditions.
