Latest forecast models from the Institute of Meteorology and Water Management (IMGW) and ECMWF indicate a high-pressure ridge over Central Europe driving clear skies and light winds in Warsaw on April 18, positioning trader consensus around a maximum temperature of 17°C (49% implied probability) or 18°C (30.5%). This marks a warming trend from April 17's cooler highs near 14-15°C, with abundant sunshine enabling above-average solar heating—mid-April climatological norms hover at 13-14°C. Model ensembles show tight agreement within 1-2°C spread, though minor cloud variability or northerly gusts could cap peaks lower. IMGW's weekend outlook emphasizes more sun on Saturday, with official observations from Warsaw stations resolving the market by evening.
