Recent model runs from global and regional ensembles indicate a daytime maximum near 21–22°C for Cape Town on 28 August, driven by northwesterly flow advecting milder maritime air ahead of an approaching cold front. Variable cloud cover and light winds will moderate solar heating, while dew points near 8–11°C limit further warming; historical August highs average 18°C, but recent above-normal conditions support the current market clustering. Official resolution at Cape Town International Airport will hinge on the precise timing of any wind shift or increased cloudiness later in the day.
