Weather in Guangzhou in October
China · 20-year averages, October
Prime time. October is about as good as Guangzhou gets. Highs average 29 °C, lows 19.3 °C, and rain falls on 6 days — nothing in the month is working against you.
October ranks 5 of 12 in Guangzhou: past the worst of the year but short of December, which is the month to book if the dates are open.
Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29 °C days and 19.3 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 11 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest October day reached 33.6 °C and the coldest night fell to 8.3 °C, and the wettest single day dropped 71 mm — roughly 127% of the month's rain in one day.
This is the volatile part. October rainfall has ranged from 2 mm to 138 mm across the twenty years measured — a 136 mm spread around an average of 56 mm. The average is real but almost no individual October looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 7.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.
How October sits in the year
The month is on the way down: 1.9 °C cooler than September, with November dropping another 2.7 °C. The first week and the last are not the same trip. Rain has already shifted: 10 days fewer than September had.
Daylight in October
11.7 hours of daylight, losing 0.6 hours across the month. That is between Guangzhou's extremes of 13.5 and 10.7 hours, so days are long enough not to constrain the plan.
An inland climate
Despite being inland, the year stays fairly even: 23 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October in Guangzhou versus nearby
If Guangzhou is one option among several, the nearby comparison is worth making. Shenzhen is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Haiphong is the weaker option in October — within a degree on temperature, 5 days more rain.
So: October works, with December the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
