Climate overview
Temperature
Monthly mean temperatures reach their highest point in January, at 21.8 °C, and their lowest in July, at 12.3 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad temperature pattern rather than the warmth of an afternoon or the conditions on any one day. Across the calendar months, the unweighted mean of the monthly mean temperatures is 17.1 °C. It provides a broad summary, but does not weight months by their number of days.
Rain
Mean daily rainfall is highest in June, at 3.84 mm/day, and lowest in February, at 0.36 mm/day. The figures are daily averages for those months, not monthly rainfall totals, and a lower mean does not guarantee rain-free days or indicate how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 1.42 mm/day. This offers a year-wide summary of the supplied monthly averages, not a day-weighted annual average.
Sunshine
Mean daily sunshine reaches its highest level in December, at 12.78 hours/day, and its lowest in June, at 7.58 hours/day. These averages can help with planning outdoor time, but sunshine duration is not the same as day length and does not guarantee the conditions on a particular day. The unweighted mean of the monthly mean daily sunshine durations is 10.30 hours/day. It summarizes the calendar-month averages without weighting them by the number of days in each month.
Best Travel Time Guide for Cape Town, South Africa: Ideal Seasons and Weather Insights
If lower average rainfall is a priority, February is the conditional option in these data, with mean daily rainfall of 0.36 mm/day; that average does not rule out wet days. For rain preparation, note that June has the highest monthly mean daily rainfall, 3.84 mm/day, so having a rain-ready layer is prudent rather than assuming every day will be wet. Visitors prioritising cooler monthly mean conditions can look to July, when the monthly mean is 12.3 °C. This is not a daytime high or a forecast, so flexible layers are more useful than treating the average as a promise about daily temperatures.
For planning around average sunshine duration, December has the highest mean at 12.78 hours/day, while June has the lowest at 7.58 hours/day. These figures can inform choices about outdoor sightseeing, but they measure sunshine duration, not daylight length, and cannot guarantee clear weather during a visit.
