16 Day Weather Forecast

Overview

A mixed pressure pattern may well develop, leading to changeable weather. Rainfall looks limited, with most days staying dry.

A sharp change in overnight temperatures looks set to develop within the next day or so, and overnight lows are set to drop through the period.

Pleasant temperatures are anticipated, with highs around 20°C or a little above. The mildest conditions are forecast on on Saturday 15 August, with highs near 24°C. Overnight temperatures will dip lowest on Sunday 23 August, falling to 9°C.

There will be some wet spells, with rainfall totals near 27mm 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.
