UK long range weather forecast
An unsettled picture is likely for this period, with all parts of the country seeing showery spells as well as periods of more prolonged rainfall at times. However, southern and western areas are expected to see the most frequent and heaviest of the rainfall. Drier and calmer conditions could be seen at times, but likely only for short interludes. It will often be windy during this period, with a risk of gales at times, particularly along coasts in the west and southwest. Overall, it is likely to feel rather cold as temperatures look set to be around average or below. During any of the brief calmer interludes overnight frost is also possible in the North.
Updated:
A potential change in the weather is signalled around the middle of October. Whilst further rain and strong winds are likely at times, spells of fine and dry weather could become more widespread and long-lived. At night, these calmer conditions would allow frost and fog to form more readily. At this time of year, there is potential for fog to linger well into the daytime. Overall, temperatures probably recovering close to the seasonal average for October.
