Recent forecasts from Chinese meteorological sources and international models indicate persistent rain and cloud cover over Guangzhou on October 3, driven by monsoon influences, which should moderate overnight cooling and support lowest temperatures in the 24–26°C range. This aligns with current market-implied odds favoring those buckets around 35%, while the 30°C+ outcome at 46.5% reflects trader caution over possible clearer intervals or delayed cooling. Historical October averages near 22–23°C provide baseline context, but active precipitation and high humidity this week reduce the likelihood of sharper drops. Updated model runs from the China Meteorological Administration and ensemble guidance over the next 48 hours represent the key near-term catalyst for any odds shifts.
