Climate Chart of Nagoya, Japan

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures are lowest in January, at 3.5 °C, and highest in August, at 27.5 °C. These figures describe monthly averages, not the daytime maximum or the temperature on any particular date, so visitors should allow for day-to-day conditions to differ from the broad monthly profile. The unweighted mean across the calendar-month temperature means is 15.3 °C. It provides a compact summary of the monthly averages, but is not a day-weighted annual average.

Rain

Mean daily rainfall is highest in July, at 8.35 mm/day, and lowest in January, at 1.68 mm/day. Those figures identify the months with the highest and lowest average daily amounts; they do not show how often rain falls or guarantee conditions on an individual day. Across the monthly means, the unweighted mean daily rainfall is 4.84 mm/day. This is a daily average, not a monthly accumulation, so it should not be read as the amount expected over an entire month.

Snow

The highest monthly mean daily snowfall is recorded in February, at 1.37 mm/day; the unweighted mean across the monthly snowfall means is 0.18 mm/day per day. These are average amounts, not evidence of how many days have snow, snow depth or persistent snow cover, and they do not establish skiing conditions.

Sunshine

Mean daily sunshine reaches its highest monthly value in August, at 9.92 hours/day, and its lowest in December, at 7.29 hours/day. These averages can help with planning outdoor time, but sunshine duration is not the same as day length and does not guarantee clear skies on a particular day. The unweighted mean of the monthly sunshine-duration means is 8.33 hours/day per day. It summarizes the calendar-month averages rather than a day-weighted annual figure.

Best Travel Time Guide for Nagoya, Japan: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly averages, January is the relevant option, with a monthly mean temperature of 3.5 °C; this does not predict daytime highs or the weather on a specific visit. Those prioritising lower average rainfall can consider January, when mean daily rainfall is 1.68 mm/day, while keeping in mind that a lower average does not guarantee dry days or indicate rain frequency. Rain preparation is especially relevant for travel in July, the month with the highest mean daily rainfall at 8.35 mm/day. This average does not specify whether rainfall is frequent or concentrated on particular days, so it is not a day-by-day forecast.

For outdoor sightseeing planned around the highest mean daily sunshine, August records 9.92 hours/day; the lowest mean daily sunshine is in December, at 7.29 hours/day. These duration averages may inform daylight outdoor planning, but they are not day length and cannot promise sunshine during a visit. Although the highest monthly mean daily snowfall occurs in February at 1.37 mm/day, that measure alone cannot tell visitors how many snowy days to expect or whether snow will lie on the ground. Treat it as an average amount, not a guide to snow cover or skiing conditions.
