16 Day Weather Forecast

Overview

An area of high pressure looks set to dominate, favouring settled weather. Dry conditions should prevail for the majority of days.

Mild conditions are in prospect, at least on some days, with highs reaching the mid-teens. The mildest conditions are anticipated on Wednesday 30 September, with highs near 21°C. The coldest nights look to come later in the period, potentially near 5°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.
