London's Seasons
London has a temperate oceanic climate very similar to Paris — four proper seasons, no dry/wet split. Rain falls fairly evenly all year (40–68mm/month). London's reputation for constant rain is a bit exaggerated; what's actually true is a lot of grey, overcast days even when it isn't raining.
WARM SEASON
April – September
Best overall visiting window
- Mild to warm, longer daylight hours
- Best for parks, walking tours, outdoor markets
- Peak crowds & prices: Jul, Aug (school holidays)
- Best value within warm season: Apr, May, Sep
COOL SEASON
October – March
Cold, but still very visitable
- Short days, museums & indoor sights shine
- Christmas markets & lights in December
- Coldest: January & February
- Lowest flight and hotel prices of the year
ℹ️ Good to know: July–August is driven up mostly by UK school summer holidays, not just weather — families flood the city and prices follow. Wimbledon (late June–early July) and the Notting Hill Carnival (August bank holiday) also create short but sharp local crowd/price spikes.

Frequently Asked Questions
What is the best month to visit London?
April to June and September offer the best weather-to-crowd ratio — mild temperatures, longer daylight hours, and noticeably fewer crowds than the July/August school-holiday peak. May and September give nearly the same pleasant weather with lower prices.
Is London really as rainy as people say?
London's reputation for constant rain is a bit exaggerated — its annual rainfall is similar to or slightly less than Paris. What's genuinely true is that London has more grey, overcast days year-round, even on days when it isn't actually raining.
Is it worth visiting London in winter?
Yes, especially for budget-conscious travellers. Flights and hotels are noticeably cheaper, major museums (which are free anyway) have shorter queues, and December brings Christmas lights and markets. Just pack warm layers — daytime temperatures hover around 3–8°C.
Which months are the most crowded in London?
Late July through August (UK school summer holidays) and the last two weeks of December are the busiest. Wimbledon (late June–early July) and the Notting Hill Carnival (August bank holiday) also create short, sharp local crowd and price spikes.
How much does the temperature change across the year in London?
From around 2–8°C in January to 13–23°C in July. It's a smaller swing than Paris's extremes, but London compensates with more consistently overcast skies — pack layers and a compact umbrella regardless of season.
What's the cheapest time to visit London from India?
January, February and November tend to have the lowest flight and hotel prices, since they fall outside both the summer school-holiday rush and the December holiday spike. It's cold, but layering up makes it very manageable — and the museums are free year-round regardless.
