Recent AEMET forecasts and numerical weather models show Madrid's overnight minimum on August 24 stabilizing near 20°C, driven by increased cloud cover, light rain, and southwesterly flow that limits radiative cooling. Observations through the evening confirm temperatures holding in the low 20s Celsius across central stations, consistent with climatological patterns for late August where average lows sit around 18–19°C but current synoptic conditions suppress further drops. Market-implied odds near 99% on 20°C reflect this consensus from official guidance, with traders assigning skin-in-the-game weight to the narrow forecast range. A clear-sky break or stronger nocturnal drainage could push readings to 19°C or 21°C, though model agreement makes such shifts unlikely before midnight resolution.
