Notably, the number of days with precipitation is quite significant, especially in the winter months (December and January can have over 20 such days), suggesting frequent but not very heavy snowfall. Summer months, such as July and August, also show a high number of days with precipitation, which may indicate frequent but light rains.

The climate in Hanamaki Onsen is characterized by noticeable seasonal temperature changes. The annual temperature range here is quite wide: from frosty winter days to warm summers. The coldest month is usually January, with an average temperature of around -3.0°C, when nightly lows can drop to -6.3°C, and daily highs barely cross the freezing mark, reaching an average of 0.4°C. Conversely, August is the warmest month, with an average temperature of 23.5°C. During this period, daytime heat can reach 26.7°C, while nights remain warm with temperatures around 20.2°C.

The summer months in Hanamaki Onsen, from June to August, bring pleasant warmth. In June, the average temperature is 18.0°C, gradually rising towards July (22.4°C) and peaking in August. Daytime temperatures in summer fluctuate in a comfortable range from 21.8°C to 26.7°C, making this time suitable for walks and outdoor activities. Nights also remain warm, with minimum temperatures from 14.1°C to 20.2°C. Significant extreme jumps between daytime and nighttime temperatures in summer are usually not observed; the difference is about 6-7 degrees.

Winter in Hanamaki Onsen, covering December, January, and February, is quite cold. Monthly average temperatures drop below freezing: -0.6°C in December, -3.0°C in January, and -2.2°C in February. At night, the thermometer regularly shows sub-zero values, dropping to -6.3°C in January. During the day, the air temperature often stays around or slightly above freezing, with maximum values from 0.4°C to 2.3°C. In the winter months, the difference between day and night temperatures is slightly smaller than in other seasons, amounting to approximately 5-7 degrees, indicating consistently cool weather.

In Hanamaki Onsen, precipitation is observed year-round, however, its character and intensity vary noticeably depending on the season. Winter months, from December to February, are characterized by frequent precipitation, which, given average sub-zero temperatures (for example, in January the average temperature is -3.0°C, and the maximum is only 0.4°C), most likely falls as snow. January and December stand out with the highest number of days with precipitation – 21 and 22 days respectively, although the total amount of precipitation in these months is relatively small (3-4 mm).

With the arrival of spring, in March, when the average temperature rises above freezing, snow gradually gives way to rain. The number of days with precipitation decreases slightly, averaging 13 to 15 days in the spring months. Summer, especially July and August, is the period with the highest amount of precipitation – 6 mm in each of these months. Rains fall quite often during this time, approximately 18 days per month, which suggests regular but not necessarily torrential rainfall.

In autumn, precipitation intensity gradually decreases. September is still quite wet (5 mm of precipitation and 14 days with it), but October can be considered a relatively dry month, as it counts the fewest number of days with precipitation – only about 12, with a total volume of 4 mm. In November, the number of days with precipitation rises again to 15, and the drop in temperature towards the end of the month foreshadows the transition to winter snowfalls.

When planning a trip to Hanamaki Onsen, it is important to consider significant seasonal weather fluctuations and be prepared for changeable conditions. Winters here are cold, with temperatures often below freezing (averaging -3.0°C to -0.6°C) and a high number of days with precipitation (17-22 days per month), which will likely be in the form of snow, given the low total precipitation norm (3-4 mm). Summer (June-August) is warm (average temperature 18°C - 23.5°C) and humid, also with frequent, though usually not heavy, rains (15-18 rainy days with 5-6 mm of precipitation). Spring and autumn are transitional seasons with moderate temperatures but still a chance of precipitation. Regardless of the season, comfortable walking shoes are your best friend, as you will likely be walking a lot.

For winter months (December-February), pack your warmest clothes: thermal underwear, fleece sweaters, an insulated, windproof, and waterproof jacket, a hat, gloves, and a scarf, as well as waterproof shoes. In spring (March-May) and autumn (September-November), when temperatures fluctuate (in spring from minimums of -0.7°C to maximums of 18.5°C, and in autumn from 2.4°C to 22.9°C), the layering principle will come in handy: T-shirts, long-sleeved shirts, sweaters, and a medium-weight jacket that can be taken off or put on depending on the weather. In summer (June-August), choose light and breathable clothing. Considering that in all seasons in Hanamaki Onsen there are quite a few days with precipitation, despite their small total amount, an umbrella or a light raincoat will become indispensable companions. Do not forget sunscreen for summer months and warm sunny days in spring and autumn.
