What is the outlook for the next few days in Newhaven?
The coming week sees temperatures hovering near seasonal averages, with daytime highs unlikely to stray far from the low teens. The most notable factor will be the wind, picking up from the southwest at times, which may make it feel cooler, particularly along the seafront. Rain is likely to arrive in short, showery bursts rather than prolonged downpours, with the best of any dry weather expected midweek. For a broader view, you can check our UK weather hub.
