16 Day Weather Forecast

Overview

Conditions appear variable for most of the period. Dry conditions should prevail for the majority of days.

The overall trend is for daytime temperatures to fall through the period, and conditions may turn more unsettled as the period progresses.

Hot conditions are predicted on at times, with highs reaching into the 30s. Tuesday 14 July looks like the hottest day, with temperatures climbing to 31°C. The coolest night is expected on Tuesday 21 July, with lows around 10°C. There is a notable spread between the highest and lowest temperatures, so conditions will vary considerably.

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.
