Comfortable for walking, cool when you stop

The daytime average makes October manageable for walking in layers, but it is not reliably warm enough to leave your jacket behind. The warmest 10% of days reach 20.3°C or more, so a mild afternoon is possible; treat that as a bonus rather than the basis of your packing. Nights deserve more attention: the coldest 10% fall to 2.2°C or lower, making a warm outer layer useful if you plan to stay out late. There are about 10.5 hours of daylight but only 3.8 hours of sunshine a day, so do not count on sunshine to make a cool afternoon feel warmer.

Keep outdoor plans flexible

Rain is the main practical catch, rather than excessive heat. About 9 days have measurable rain, enough to make a waterproof jacket and shoes that cope with wet pavements sensible choices. That does not mean you need to spend the trip indoors, but avoid making every part of your day depend on dry weather. Keep outdoor time easy to rearrange, and have an indoor alternative when conditions turn wet. A jumper beneath your jacket gives you more flexibility than relying on a light top alone. October suits travellers who can accept mixed weather; it is a weaker choice for a holiday built around sitting outside.
