16 Day Weather Forecast

Overview

Conditions will often be unsettled, with areas of low pressure dominating. Some wet days are likely, but there should be dry breaks in between.

Conditions appear set to turn more settled later on.

Daytime highs in the low teens at first, above average for November, look set to ease back into the upper single figures later on, closer to average. Temperatures will peak on Tuesday 17 November, reaching 15°C, which is mild for mid-November. The coldest nights look to come later in the period, potentially near 2°C, subject to change. If so, sheltered and rural areas could see patchy frost on clearer nights.

Gusty conditions are predicted around Tuesday 17 November, with winds reaching 50mph. Rainfall totals look substantial, with around 97mm over the period. The wettest conditions are expected on Thursday 19 November.

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.
