Nerima experiences clear seasonality in its rainfall distribution throughout the year. Overall, monthly rainfall is relatively low, suggesting mostly light rain or drizzle rather than heavy downpours, even during the wettest periods. The highest amount of precipitation falls from June to October, while winter is characterized by drier weather.

The wettest months in terms of rainfall volume are June, July, and October, each receiving 7 mm. July also stands out with the highest number of rainy days—about 17. June, August, and September also feature frequent precipitation: June sees 7 mm, August 5 mm, and September 6 mm, with each of these months having about 16 wet days. During this period, from late spring to mid-autumn, rain occurs more often, but based on the total volume, it is generally light. The spring months—March, April, and May—also have a significant number of wet days (13–14 days) but with a lower rainfall volume (4 mm).

The driest months in Nerima are the winter months. December has the lowest rainfall, just 1 mm, and the fewest wet days—averaging 6. January is very similar: 2 mm of rainfall and also 6 wet days. February (2 mm, 9 wet days) and November (3 mm, 9 wet days) also belong to the drier periods. Given that the minimum temperature in January can drop to -0.0°C, and stays around 1–2°C in December and February, occasional snow is possible during these winter months alongside light rain, though the low overall precipitation volume suggests it will be minor.

In winter (December–February), it is quite cool here, with average temperatures ranging from 4.5°C to 6.7°C, and nighttime temperatures can drop to freezing.

Although precipitation is low, the number of rainy days (up to 9 in February) suggests having waterproof shoes and perhaps a light rain jacket.

Spring (March–May) and autumn (September–November) are transitional periods with moderate temperatures. In spring, the temperature gradually rises from 10°C to 19°C, while in autumn it decreases from 24°C to 12.5°C. For these seasons, layering is ideal: T-shirts, long-sleeved shirts, light sweaters or fleece jackets, and a transitional jacket. The number of rainy days remains significant (13–16 days), so an umbrella or raincoat will come in very handy. Summer (June–August) in Nerima is warm and humid, with average temperatures reaching 26–28°C. Lightweight, breathable clothing made from natural fabrics is recommended. June and July are the rainiest months with 16–17 days of precipitation, so a light raincoat or umbrella is a must. Don't forget sunscreen and a hat for sunny days.

Regardless of the season, comfortable walking shoes are your main companion in Nerima, as you will likely be doing a lot of walking. Given the frequent precipitation throughout most of the year, waterproof or quick-drying shoes are a good choice. An electronics adapter and a portable power bank will also be useful for any trip to Japan.
