Harleston sees a mix of bright spells and cloud today, with the live forecast above showing the likely trend into the evening. This South Norfolk market town, inland from the Suffolk border and close to the River Waveney, can expect a modest breeze and temperatures staying near seasonal norms.
Will it rain in Harleston today?
The live forecast above indicates any showers passing through Harleston should be light and isolated this afternoon. Most of the settled weather arrives from the east, so the town avoids the heavier bands that sometimes push inland from the Norfolk coast at Winterton or Great Yarmouth.
What’s the weekend outlook for Harleston?
High pressure building from the continent should keep Harleston mostly dry through Saturday and Sunday, though cloud may bubble up during the afternoon. Overnight lows could dip into single figures under clearer skies — a typical early-autumn pattern for this part of East Anglia.

Where can I get the most reliable forecast for Harleston?
The live forecast above is updated regularly. For additional detail, the Met Office provides hourly and 10-day data for Harleston, while BBC Weather also covers the town under its Norfolk forecasts. Cross-referencing both sources gives a solid overview.
Does weather in Harleston differ much from weather in Norwich?
Yes, slightly. Harleston sits further south and inland, so it often runs a fraction cooler than Norwich overnight, especially in spring and autumn. Norwich’s proximity to the coast at Great Yarmouth moderates its temperatures a little more than Harleston’s.
How does the A140 affect local weather conditions?
The A140 runs north–south past Harleston but does not create any microclimate effect. However, drivers heading toward Norwich or Ipswich should be aware of low morning sun and occasional mist patches in the river valleys, particularly near Pulham Market.
