AnyWeather calculated both city baselines from daily ERA5 reanalysis for 1991-2020, retrieved through the Open-Meteo Historical Weather API. ERA5 combines models and observations on a grid; it is not a city-center station record. Local terrain, coastlines, elevation, urban heat, and storms can differ from these values.
London to Paris: decisions by travel period
The two cities are close enough for the same weather system to affect both, but timing, wind, and urban exposure can still make a day feel different. For a rail trip, compare the departure morning with the Paris arrival window rather than assuming one daily icon covers the whole journey.
What changes through the year
| Period | London | Paris | Decision |
|---|---|---|---|
| December-February | London can be damp, windy, and cool, with occasional frost or disruption from winter weather. | Paris is also cool; exposed viewpoints and evening walks can feel colder than sheltered streets. | Wear layers that work in both cities and keep one weather-resistant outer layer accessible during the journey. |
| March-May and September-November | Fast changes between cloud, showers, wind, and brighter intervals are common planning concerns. | Paris can shift through a similar range, but the rain window may arrive earlier or later than in London. | Use hourly rain timing for each city and keep one flexible indoor stop instead of cancelling a full day from a rain symbol. |
| June-August | Warm spells vary in length, and transport or rooms without cooling can remain uncomfortable after sunset. | Paris heat can build strongly in dense streets and exposed attractions, while thunderstorms may interrupt outdoor plans. | Check overnight lows and official heat warnings, then schedule exposed walking for the cooler part of the day. |
Route-specific checks
- Eurostar day
- Check weather at both stations and at your actual arrival hour; keep rain protection and one layer in hand luggage, not checked or buried.
- Full walking day
- Compare hourly rain, wind, and feels-like conditions in Paris. The departure weather in London is not a proxy for the afternoon at your destination.
- Warning in either city
- Read the affected area and valid time. A warning after you leave London may still apply when you arrive in Paris, or vice versa on the return.
How to interpret this comparison
