16 Day Weather Forecast

Overview

A mixed pressure pattern is likely, leading to changeable weather. Rain will feature on several days, interspersed with drier spells.

Warm or very warm conditions are forecast on, with daytime highs in the mid-to-upper 20s. Wednesday 26 August looks like the warmest day, with temperatures up to 25°C. Minimum temperatures remain comfortable, dipping to 11°C on Saturday 5 September.

Rainfall totals could be significant, with around 50mm over the period.

These forecasts use interpolation to improve accuracy for your specific location, and are powered by either ECMWF or GFS model data depending on your selection. As with all weather forecasts, confidence decreases rapidly beyond 5 days ahead — treat the later dates as a heads-up about possible conditions rather than a firm prediction.

If you have a moment, please let us know what you think.
