16 Day Weather Forecast

Overview

High pressure influence is anticipated, keeping conditions largely calm and settled. Much of the period looks relatively dry.

A sharp change in overnight temperatures is predicted during the second week.

Pleasant temperatures are in prospect, with highs around 20°C or a little above. Later in the period there are signs of highs near 24°C, though confidence at that range is low. The coldest nights look to come later in the period, potentially near 8°C, subject to change.

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.
