However, the Shoreham Airport webcam showed snow on the higher parts of Shoreham, and this remained visible for several days.

Wind

January was not a ‘southwesterly’ month, although winds from that direction were dominant on roughly a third of the days. The middle part of the month was mostly anticyclonic, with winds often light and variable. Whereas at either end of January it was windier, with winds either from the southwest, or the southeast, ahead of Atlantic weather fronts, followed by northwesterly winds once the frontal systems had passed to the east. At Shoreham Airport, the year began very windy, with gusts from the southwest frequently exceeding 30 knots (34 mph). The highest gust was 45 knots (51 mph) in the late morning before the wind quickly abated early in the afternoon.

It stayed windy for a further 24 hours, and the southwesterly wind gusted to 38 knots (43 mph) early in the morning on the 6th. The next spell of windy weather was not until the 23rd. On the afternoon of the 23rd, southwesterly gusts reached 35 knots (40 mph), and after the briefest of lulls, the southwesterly wind gusted to 45 knots (53 mph) on the morning of the 24th. The 26th was a windy day, but with the wind blowing from the south or southeast. The highest gust was in the afternoon, with 39 knots (45 mph) recorded.

Fog

There was no fog observed in this part of Shoreham, but there were several dull days around mid-month, and on these days, the cloud lowered on to the higher parts of the town and produced hill fog.

Steady rain in the afternoon, evening and overnight on the 18th produced 18.0 millimetres (0.71 ins.).
