16 Day Weather Forecast

Overview

Conditions appear variable for most of the period. A number of days will see rainfall but there will be dry periods too.

The overall trend is for daytime temperatures to fall through the period.

Warm or very warm conditions are predicted on, with daytime highs in the mid-to-upper 20s. The warmest conditions are expected on Thursday 3 September, when temperatures may reach 27°C. Wednesday 9 September sees the lowest temperatures, though remaining above 8°C.

A blustery spell looks set to develop around Friday 11 September, bringing gusts of 40mph. There will be some wet spells, with rainfall totals near 37mm 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.
