In Plymouth today, the live forecast above shows typical conditions for a city on the south-west coast: variable cloud, a moderate breeze, and temperatures likely in the range of 8–12°C. The maritime climate means changeable weather is normal, so see the live widget for up-to-the-minute details.
What does the live forecast actually tell you?
The live widget above pulls data from the Met Office and gives you immediate readings for temperature, wind speed and direction, humidity, and the chance of rain. In a coastal city like Plymouth, the wind direction matters more than inland locations – a south-westerly breeze usually brings milder, wetter air, while a north-easterly can feel sharper and drier. Use the hourly breakdown to see if conditions will shift during the day; the 7-day outlook is a reliable guide but always check the live update before heading out.
Plymouth climate through the year: highs, lows and rainfall
Plymouth sits on the sheltered side of the Tamar estuary, so it enjoys a milder version of the UK’s already mild maritime climate. The city receives around 900–1,000 mm of rain annually, spread fairly evenly, though October through January tend to be wettest. Below are typical seasonal ranges based on long-term Met Office averages.
Spring: growing warmth, still changeable
March sees average highs of 9°C, rising to 13°C by May. Showers are common – April can be one of the drier months (around 60 mm) but expect a mix of sun and passing rain. Wind speeds gradually ease, making it a pleasant time for coastal walks, especially along the South West Coast Path.
Summer: warm, not hot, with reliable sea breezes
July and August are the warmest months, with typical highs of 18–19°C. The water in Plymouth Sound warms slowly, so swimming is best from late July. Thunderstorms can develop on still, humid days, but most summer days are dry with a light south-westerly wind. Rainfall totals are at their lowest, around 55–60 mm per month.
Autumn: mild and increasingly wet
September remains pleasant, often with high pressure bringing settled spells. October and November see Atlantic low-pressure systems moving in, pushing monthly rainfall above 100 mm. Temperatures cool slowly – October highs are still around 13°C, dropping to 10°C by November. Fog can form in the early morning over the water.
Winter: damp, but rarely freezing
Winter lows rarely fall below 2°C, and snow is very unusual – you might see one or two dustings a decade. Instead, expect long spells of overcast skies and moderate rain. January is the wettest month, averaging 110 mm. Strong south-westerly gales sometimes force the local harbour to suspend ferry services; check the UK weather warnings page if stormy weather is forecast.
Best time to visit Plymouth and what to pack
For the warmest, driest days, aim for late June through early September. But if you prefer fewer crowds, May and September still offer decent weather – highs around 16°C and lower rain expectancy than midwinter. Pack layers at any time of year: a lightweight waterproof jacket, a mid-layer like a fleece, and comfortable walking shoes. Even in summer, the sea breeze can feel cool, so a long-sleeved top is useful for evenings.
Local microclimate notes and forecasts from other services
The city’s position inside the Tamar estuary and the lee of Dartmoor gives it slightly less rainfall than exposed coastal areas to the west (such as Penzance). Plymouth’s famous “Barbican” and Hoe can be a degree or two warmer than the official Mount Batten reading because of sheltering buildings. Many residents cross-check the live widget with BBC Weather Plymouth or AccuWeather Plymouth for alternative hourly breakdowns, but the Met Office remains the primary source for official warnings. For a 30 day weather forecast Plymouth UK Met Office style outlook, note that long-range predictions are broad trends; the 10-day forecast is the most reliable horizon.
Frequently asked questions about Plymouth weather
What is the weather in Plymouth tomorrow?
The best answer is the live forecast above – it updates hourly. By late afternoon the next day’s conditions are usually clear: expect a low of around 7°C and a high near 12°C if the south-westerly flow continues, with a 40–60% chance of rain depending on the pressure pattern.
What is the weather in Plymouth for the next 10 days?
The 10-day forecast widget on this page gives a day-by-day breakdown. Typical variability means the second half of the range is less certain, but you can expect the maritime pattern: alternating bands of cloud and showers, with temperatures staying close to the seasonal average – around 10–14°C in spring and autumn, and 16–19°C in summer.
Is a 14-day forecast for Plymouth reliable?
Fourteen-day outlooks from sources such as the Met Office or AccuWeather show broad trends (e.g., “unsettled” or “drier than average”) rather than precise daily details. For specific planning, the 7-day and 10-day forecasts are far more accurate. In Plymouth’s changeable maritime climate, even a 5-day outlook can shift.
Does it rain a lot in Plymouth?
Yes, compared to many inland UK cities, but less than you might expect for a coastal town in Devon. Annual rainfall is about 900–1,000 mm – similar to Manchester. The rain falls on roughly 150–160 days a year, but it often comes as light to moderate drizzle rather than heavy downpours. Drier months are April through August.
