Climate overview
Temperature
The monthly mean temperature reaches its highest point in January at 26.7 °C, while the lowest monthly mean occurs in July at 17.4 °C. These are averages for whole months, not daytime maximum readings, so individual days can differ from the monthly pattern. The unweighted mean across the monthly temperature means is 22.4 °C. It gives a compact overview of the annual pattern, but is not a day-weighted annual average and does not indicate the temperature expected on a specific visit.
Rain
Mean daily rainfall is highest in October at 6.51 mm/day and lowest in August at 2.94 mm/day. These figures describe daily averages within those months, not monthly totals; they do not show how often rain falls or guarantee wet or dry conditions on a particular day. The unweighted mean of the monthly daily-rainfall means is 4.88 mm/day. This is a broad summary rather than a day-weighted annual average, and should not be read as a forecast for any single day.
Sunshine
Average daily sunshine is greatest in December at 10.73 hours/day and least in June at 7.07 hours/day. Sunshine duration can help with planning outdoor time, but it is not the same as day length and does not specify when sunshine occurs. The unweighted mean across monthly sunshine means is 9.10 hours/day. It provides a general reference across the calendar, not a day-weighted annual figure or a promise of clear skies.
