Locked into a busy day? Here's the play.

–9am

Own the morning.The day-trip wave lands mid-morning; the headline sights before nine are effectively yours.

10–5

Go where the day-trippers don't.Away from the headline sights it stays manageable all day. Save the marquee ones.

5pm+

Take the city back.Day-trippers leave by early evening — the same squares empty out and the light is better.

On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.

July weather in London

Comfortably warm — around 23°C / 73°F, easy shirtsleeve weather, with rain on about 11 days, so keep a layer handy. The days are long too — close to 16 hours of light — so the evenings stay open for walking once the heat drops.

London gets rain on about 11 days in July, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds. Browse on Amazon ↗

Is July worth it in London?

Heavy crowds and only poor weather to show for it — a poor trade. For better value, come in June or September.

Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
