Recent meteorological forecasts for Karachi indicate peak daytime temperatures on May 18 will likely settle near 34–35 °C, reflecting the seasonal strengthening of solar heating combined with elevated humidity from the Arabian Sea that limits nocturnal cooling. Official outlooks from the Pakistan Meteorological Department note a gradual warming trend through mid-May, with minimal cloud cover and light winds expected to allow surface temperatures to approach or briefly exceed 35 °C in urban areas. Model consensus shows modest spread around these values, as small shifts in onshore flow or brief convective activity could cap readings at 34 °C or push them toward 36 °C. Traders therefore price the closely matched 34 °C, 35 °C, and 36 °C-or-higher bins near parity, reflecting genuine uncertainty in the final observed maximum.
