Trader consensus on Polymarket reflects profound uncertainty in short-range forecasts for Busan's highest temperature on April 6, with all outcomes priced equally at 25.5% implied probability, signaling wide model spread amid spring variability. Korea Meteorological Administration short-term guidance and international sites like TimeandDate project daytime highs around 17°C (63°F), but discrepancies arise from potential frontal passages, cloud cover influencing solar heating, and sea breezes moderating coastal warmth. Historical April averages hover at 15–19°C, with recent mild conditions (current highs near 17–20°C) offering little directional bias. Key differentiators include wind direction—southerlies boosting temps above 20°C, northerlies capping below 15°C—and updated model ensembles from KMA expected April 4–5, which could sharpen probabilities before resolution.
