**Current forecasts and climatology position 31–33°C as the most probable range for Karachi’s peak temperature on August 15.** August averages place daily highs near 31–32°C (88–90°F), with the city’s coastal location and Arabian Sea influence typically moderating extremes through persistent sea breezes and humidity. The southwest monsoon remains the dominant control: weak-to-moderate currents and increased cloud cover in early-to-mid August have produced partly cloudy skies and occasional light showers or drizzle, which limit daytime heating. Recent model guidance and agency outlooks (including AccuWeather and Met Office summaries) show highs clustered around 29–32°C for the 14–15 August window, consistent with below-normal rainfall keeping conditions stable rather than excessively humid or clear. Trader sentiment therefore clusters tightly around the historical mean and near-term forecasts, with 32°C leading at 36% implied probability because it matches both climatology and the latest consensus. Probabilities fall sharply outside 30–34°C because significant deviations would require either unexpected monsoon strengthening (cooler) or a rare clear-sky heat spike (warmer), neither of which is currently signaled by official monitoring. Updated Pakistan Meteorological Department briefings and final 48-hour model runs remain the key near-term catalysts.
