Climate overview
Temperature
The monthly mean temperature is lowest in January at 9.4 °C and highest in August at 21.9 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad monthly temperature pattern rather than the warmth reached on a given afternoon. Across the calendar-month means, the unweighted mean is 15.6 °C. It offers a compact summary of the supplied monthly averages, not a day-weighted annual average; daily conditions can still differ from these monthly figures.
Rain
Mean daily rainfall reaches its highest monthly average in November at 4.20 mm/day, while its lowest is in August at 0.21 mm/day. These are daily mean amounts associated with each month, not monthly totals, and the lower average does not establish how often rain falls. The unweighted mean across the monthly daily-rainfall averages is 2.69 mm/day. It provides an overall reference for the supplied month-level figures, but cannot indicate whether rainfall is spread evenly across days.
Sunshine
Mean daily sunshine is highest in July at 12.39 hours/day and lowest in December at 6.26 hours/day. The figures can help describe the contrast in average sunshine duration through the year, but sunshine hours are not the same as day length. The unweighted mean across the monthly sunshine averages is 9.28 hours/day per day. This summarizes the month-level figures rather than giving a day-weighted annual value, and it does not guarantee the sunshine available on a particular visit.
