Official METAR observations from Murtala Muhammed International Airport (DNMM) in Lagos, Nigeria—the authoritative resolution source via Weather Underground—confirm the highest temperature on April 20, 2026, reached 28°C or below, driving Polymarket's 100% trader consensus on this outcome. Persistent low-level clouds and afternoon thunderstorms, as predicted by Nigeria Meteorological Agency (NiMet) forecasts, sharply reduced solar insolation and suppressed daytime heating, well below April climatological averages of 32–34°C amid the transition to wet season. This aligns with historical patterns where early rains cool urban heat islands. Realistic challenges are minimal but could include post hoc data revisions from equipment calibration issues or auxiliary station discrepancies, though airport synoptic records carry highest evidentiary weight.
