16 Day Weather Forecast

Overview

High pressure is expected for much of the period, bringing generally settled conditions. Dry conditions should prevail for the majority of days.

The period begins settled, turning changeable during the second week.

Overnight lows are set to become milder as the period progresses.

Pleasant temperatures are in prospect, with highs around 20°C or a little above. Tuesday 22 September looks like the warmest day, with temperatures up to 25°C. The coolest night is forecast on Sunday 27 September, with lows around 10°C.

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.
