Forecast models from agencies including the UK Met Office currently project a daytime maximum of 33–35°C in Shenzhen on August 13, with thunderstorm activity and cloud cover likely to cap peaks near the lower end of that range. These conditions align closely with the market’s leading outcomes at 33°C and 34°C, which together imply roughly three-quarters probability and reflect traders’ assessment of typical late-summer subtropical humidity and monsoon influences. Recent days have shown similar maxima around 32°C, and climatological August averages hover near 32°C, providing a stable baseline against which any last-minute clearing skies or reduced rainfall could push readings slightly higher. Updated model runs and local observations through the evening of August 12 will be the key near-term catalysts for any shifts in implied probabilities.
