If you’re trying to choose the best time to visit Westminster, the answer depends on what matters most to you: mild weather, smaller crowds, lower travel costs, or major London events. For the best overall balance, late April through May and September through early October are usually the strongest choices.
Quick Answer
The best overall times to visit Westminster are late April to May and September to early October. You get mild weather and long-enough days without the heaviest summer demand. For the lowest crowd levels, choose January or February; for the warmest weather, July and August are best, but expect higher demand and book major attractions early.
Key Takeaways
- Best overall balance: late April, May, September, and early October.
- Warmest weather: July and August, when typical London-area daytime highs are around 23–24°C (73–75°F).
- Lower-demand period: January and February, outside school holidays and major events.
- Busy period: Westminster Abbey says May through September, Easter, and Christmas/New Year are typically busier.
- Plan around events: ceremonies, festivals, road closures, parliamentary business, and special services can matter more than the normal seasonal pattern on individual days.
Note: The temperature figures below use the Met Office’s Heathrow 1991–2020 climate averages as a consistent London-area benchmark. Central Westminster can be slightly different on any particular day, and London’s weather can change quickly.
1. Spring (March–May): One of the Best Times to Visit Westminster
Spring is one of Westminster’s most useful seasons for sightseeing. Days get longer, temperatures rise steadily, parks begin to fill with colour, and visitor demand has not yet reached its summer peak. The trade-off is that Easter, bank holidays, school breaks, and major events can create short periods of heavy crowding.
March: Cooler, Quieter, and Better for Value
March is a transition month. Early March can still feel wintry, but daylight increases quickly and mild afternoons become more common as the month progresses.
- Weather: Using the Met Office Heathrow benchmark, the average minimum is about 4°C (39°F) and the average maximum about 12°C (53°F). Rain is possible, so bring a waterproof layer.
- Crowds: Usually lighter than in late spring and summer, although weekends and school dates can still be busy around Parliament Square and Westminster Abbey.
- Costs: Hotels and flights may offer better value than during the main spring and summer travel periods, but prices vary considerably by date.
- Best for: Visitors who want sightseeing space and are comfortable with cool weather.
April: A Strong All-Round Choice
April is one of the best months for a first Westminster visit. Temperatures are more comfortable for long walks, daylight is much better than in winter, and parks such as St James’s Park become especially attractive.
- Weather: Typical London-area averages are about 6°C (43°F) overnight and 15°C (59°F) during the day.
- Crowds: Moderate on ordinary weekdays but potentially high around Easter and major events.
- Costs: Demand begins to rise, particularly around Easter and popular weekends.
- Events: The TCS London Marathon can cause significant road closures and crowding in central London. For example, the 2027 event is scheduled for 24–25 April, with central-London finish arrangements. Check the official London Marathon information when choosing late-April dates.
May: Warmer Weather and Higher Demand
May brings warmer afternoons, long daylight hours, and some of the most comfortable walking weather of the year. It is also when visitor demand becomes more noticeable.
- Weather: Average London-area temperatures are roughly 9°C (48°F) to 18°C (65°F).
- Crowds: Expect more visitors than in March or early April. Westminster Abbey specifically identifies May through September as a typically busier period.
- Costs: Accommodation can become more expensive as summer approaches, especially around weekends, bank holidays, and large events.
- Events: The RHS Chelsea Flower Show and two May bank-holiday periods can increase demand in central London, even when the event itself is outside the immediate Parliament Square area.
If you are choosing between March, April, and May, March normally gives you the most breathing room, April offers an excellent compromise, and May gives you the warmest spring conditions with more visitors.
2. Summer (June–August): Warmest Weather and Heaviest Demand
Summer brings London’s longest days and warmest average temperatures. It is ideal if weather is your top priority, but Westminster’s headline sights can be busy and advance booking becomes much more important.
June: Long Days and Major Ceremonial Events
June combines long daylight hours with comfortable average temperatures, making it excellent for walking between Westminster Abbey, Parliament Square, Whitehall, St James’s Park, and Buckingham Palace.
- Weather: Typical London-area averages are around 12°C (54°F) to 22°C (71°F).
- Crowds: High around major attractions and especially heavy on ceremonial-event days.
- Costs: Summer demand can push accommodation and airfare higher, although there is no single price pattern that applies to every date.
- Events: Trooping the Colour takes place each June at Horse Guards Parade and can create very large crowds and transport changes around Whitehall, The Mall, and nearby Westminster streets.
July and August: Warmest Months, Busiest Sightseeing Period
July and August are the warmest part of the year, but they also overlap with school holidays and strong international visitor demand.
- Weather: July averages roughly 14°C (57°F) to 24°C (75°F), while August averages about 14°C (57°F) to 23°C (73°F). Hot spells can take temperatures well above those averages.
- Crowds: Expect busy pavements, full tours, and queues at major attractions, particularly from late morning onward on popular dates.
- Costs: Hotels and flights are often expensive during high-demand summer dates. Compare exact dates rather than assuming every summer day costs the same.
- Attraction access: Official Big Ben tours are available to UK and international visitors aged 11 and over. Standard tickets are released three months ahead, and the tour includes 334 steps, so popular dates can require planning well in advance.
Pro Tip: For a summer visit, reserve the attractions that matter most before building the rest of your day. Westminster Abbey and UK Parliament both recommend advance planning, and special events or parliamentary business can affect normal access.
3. Autumn (September–November): Mild Days and Gradually Easing Crowds
Autumn is another excellent season for Westminster. September often holds onto summer-like conditions, while October brings cooler weather and autumn colour. November is quieter but noticeably darker and wetter.
September: One of the Best Overall Months
September is a strong choice if you want comfortable sightseeing weather without relying on the hottest part of summer. Schools return, but central London remains busy with visitors and major events.
- Weather: Average London-area temperatures are about 12°C (53°F) to 20°C (68°F).
- Crowds: Usually easier than peak summer, although major events can create local surges.
- Costs: Some hotel and airfare prices begin to ease after the summer holiday period, but event weekends can still be expensive.
- Events: In 2026, Totally Thames runs throughout September, while Open House Festival runs 12–20 September. Individual venues and events vary, so check programmes before choosing dates.
October: Cooler Weather and Autumn Colour
October brings shorter days and cooler mornings, but it can be one of the most atmospheric times for walking through St James’s Park and the wider Westminster area.
- Weather: Typical averages are approximately 9°C (48°F) to 16°C (61°F).
- Crowds: Generally lower than in summer, except around school half-term dates and special events.
- Costs: Often better value than peak summer, but there is no guaranteed low-price period.
- Best for: Photography, park walks, and visitors who prefer cooler sightseeing weather.
November: Quieter but More Event-Dependent Than It Looks
November is cooler and darker, and ordinary sightseeing days can feel much calmer than in summer. However, Westminster hosts nationally important Remembrance events that can dramatically change crowd levels around Whitehall.
- Weather: Average London-area temperatures are about 5°C (41°F) to 11°C (52°F).
- Crowds: Often relatively light on normal days, but not around the National Service of Remembrance.
- Costs: November can offer good accommodation value before the Christmas travel period, although prices remain date-dependent.
- Events: The main national ceremony at the Cenotaph takes place on Remembrance Sunday, the second Sunday in November. This is different from Armistice Day on 11 November. Expect security measures and significant crowds around Whitehall and Parliament Street.
4. Winter (December–February): Festive Crowds Followed by Quieter Months
Winter is not one single low season. December can be extremely busy around Christmas and New Year, while January and much of February are normally quieter. The main drawbacks are cold weather and short daylight hours.
December: Festive but Not Necessarily Cheap or Quiet
December brings Christmas lights, services, concerts, shopping, and New Year’s celebrations across central London. That atmosphere can be wonderful, but it also attracts visitors.
- Weather: Average London-area temperatures are about 3°C (37°F) to 9°C (48°F).
- Crowds: Moderate to high depending on the date, with substantial demand around Christmas and New Year.
- Costs: Early December may offer reasonable options, while Christmas and New Year’s dates can be much more expensive.
- Events: Westminster Abbey hosts seasonal services and events, while London’s New Year’s Eve celebrations can cause extensive crowd controls and transport changes near the Thames.
January: Best for a Quieter Westminster Experience
After New Year’s crowds leave, January is one of the most appealing periods for travellers who value space more than weather.
- Weather: Typical averages are roughly 3°C (37°F) to 8°C (47°F).
- Crowds: Usually lower than during spring, summer, and the Christmas period.
- Costs: Lower visitor demand can produce attractive hotel or airfare deals, but January should not be treated as guaranteed to be the cheapest month for every traveller.
- Best for: Museums, churches, Parliament-area sightseeing, photography without summer crowd density, and travellers comfortable with short days.
February: Quiet with Slowly Lengthening Days
February remains cool, but daylight improves steadily. It can be a good compromise if you want winter-level demand without visiting during the darkest weeks of the year.
- Weather: Average London-area temperatures are around 3°C (37°F) to 9°C (48°F).
- Crowds: Generally low outside school half-term dates and major events.
- Costs: Often competitive compared with high-season dates, although prices vary by weekend and event.
- Events: Lunar New Year celebrations take place around Chinatown, the West End, and Trafalgar Square in late January or February depending on the year, so parts of central Westminster can become considerably busier.
If you’re planning a winter trip to Westminster, check opening hours shortly before you go. Westminster Abbey is a working church and can alter visitor access for special services, while UK Parliament tours can vary around parliamentary business and security requirements.

Best for Weather
- June, July, and August: Warmest average temperatures and longest daylight.
- May and September: Mild conditions without relying on peak summer heat.
Best for Avoiding Crowds
- January and February: Generally the strongest choices for lower visitor demand outside holidays and events.
- March and November: Often quieter than the main May–September visitor period.
Best for Budget Travellers
- January, February, and parts of November: Lower demand can create better hotel and airfare opportunities.
- March and October: Useful shoulder-season options if winter weather does not appeal to you.
Do not rely on a month alone when budgeting. Flight and hotel prices respond to your exact dates, events, weekends, school holidays, and how early you book.
Best for a Festive Atmosphere
- December: Christmas lights, seasonal services, concerts, shopping, and New Year’s celebrations create the strongest festive atmosphere.
Best for Photography and Autumn Colours
- October: Cooler light and changing leaves make nearby parks particularly attractive.
Best Overall Balance of Weather, Crowds, and Cost
- Late April, May, September, and early October: These periods offer the most dependable compromise for most visitors. You get comfortable sightseeing weather while avoiding at least part of the peak summer rush.
Warning: Westminster is unusually sensitive to major ceremonies, protests, state occasions, parliamentary activity, security operations, and road closures. A normally quiet month can have an exceptionally busy day. Check Transport for London’s travel tools and your attraction’s official website shortly before travelling.
Whatever month you choose, pack layers and be ready for rain. London receives precipitation throughout the year, so a small umbrella or waterproof jacket is useful even in summer. Booking your highest-priority attraction first and checking special-event dates will usually make a bigger difference to your experience than chasing a supposedly perfect month.
