Trader consensus on Polymarket reflects high uncertainty in short-range forecasts for Lagos' highest temperature on April 13, with models like GFS and ECMWF ensembles clustering around 30–33°C amid partly cloudy skies and moderating sea breezes from the Gulf of Guinea. NiMet's recent bulletins note persistent humidity and occasional dust haze early April, tempering extremes, while historical April data from NOAA shows average highs of 32°C (90°F), rarely exceeding 34°C or dipping below 29°C due to the urban heat island and coastal influences. Differentiation among close outcomes (29–36°C at 19–21.5%) stems from model disagreements on cloud persistence—thicker cover favors 29–31°C, clearer intervals 33–35°C—against low odds for extremes given climatological baselines.
