Current forecast consensus from numerical weather models supports the market's near-certain positioning on a 30°C high for Istanbul on June 15, with mid-June climatology and persistent high-pressure ridging favoring peak readings near this threshold under mostly clear skies and light southerly flow. Official guidance from sources such as the Turkish State Meteorological Service and global ensembles shows daytime maxima stabilizing around 28–30°C, aligning with historical averages that climb toward 26–28°C by mid-month. Traders' strong consensus reflects real-time model agreement and observed conditions through the day, though modest uncertainty remains from potential afternoon sea-breeze reinforcement or brief convective cloud development that could cap the peak 1–2°C lower.
