Rainfall has a seasonal rhythm

In the 2021–2025 observations, February recorded the highest average monthly precipitation at about 123.9 mm. June was the driest month in the same comparison at about 0 mm.

Monthly totals describe accumulation, not timing. Rain may arrive through frequent short showers or a few heavy days, and two journeys in the same month can feel completely different.

A wet month is not a ruined month

Wetter periods can soften light, reduce heat and change the sound of a city. They can also close outdoor facilities or slow transport. Treat rain as a routing constraint rather than an automatic reason to cancel.

Link one outdoor place with one covered alternative nearby. Markets, museums, arcades, cafés and hotel public spaces can turn a hard retreat into a deliberate second version of the day.

Design a route with quick shelter

Keep transfers short and avoid routes that require repeated long crossings. Waterproof the items that would end the day if soaked: documents, power bank, medication and a change of small essentials.

Shoes and drying time matter as much as an umbrella. A compact rain layer leaves both hands free and is easier in crowded streets, while severe-weather warnings should always override an itinerary.

Protect time as well as belongings

The food and hotel links below help build a smaller geographic loop. A nearby meal or lodging can preserve the evening when an exposed attraction becomes impractical.

Replace averages with a live forecast

Check the live forecast, official alerts and transport status before departure and again each morning. Historical averages provide context; current conditions make the decision.
