Central Weather Administration observations at Taipei Songshan Airport confirm a daily high of 27°C on April 18, 2026, driving the market's unanimous trader consensus with real capital fully backing this outcome. Hourly measurements peaked at this level amid mostly cloudy conditions and light precipitation of 0.5 mm, aligning closely with pre-day forecasts projecting 26°C highs suppressed by overcast skies and weak cold air influence. April climatology averages 25.7°C daytime highs, making this reading typical without extremes. Realistic challenges are minimal—only a rare data revision from quality control or discrepancies in the resolving Wunderground archive could shift it, though CWA's standardized shielded thermometer readings provide robust evidence. No further updates expected as observations finalize.
