Precipitation in Shiogama is distributed throughout the year; however, the summer months—especially July and August—are the wettest, both in terms of rainfall (up to 6 mm) and the number of rainy days (up to 20 days in August). Conversely, the winter months are characterized by less precipitation (about 2 mm), although the number of days with precipitation remains notable (around 14 days in January and December), which can mean frequent but light snowfall or rain.

The city of Shiogama experiences a distinct change of seasons with notable temperature fluctuations throughout the year. The hottest month is usually August, when the average temperature reaches 25.3°C, and daytime highs can rise to 27.8°C. Nights in August are also warm, with a minimum temperature of about 22.7°C. Conversely, the coldest month is January, with an average temperature of just 1.5°C. In January, nighttime temperatures regularly drop below freezing (averaging -1.5°C), while during the day the air warms up to only 4.6°C.

Summer months in Shiogama are characterized by warmth that transitions into heat. June brings pleasant warmth with average temperatures around 19.6°C (ranging from 16.6°C at night to 22.7°C during the day). In July, it becomes noticeably hotter: the average temperature is 24.0°C, with daytime peaks of 26.6°C and nighttime lows around 21.3°C. Winter, from December to February, brings cool to cold weather. In December, the average temperature stays at 3.7°C (ranging from 0.7°C to 6.7°C). February is slightly warmer than January, with an average temperature of 2.5°C and a range from -0.9°C at night to 5.9°C during the day. Overall, fluctuations between day and night temperatures are moderate throughout the year, averaging 5-7°C, which indicates an absence of sharp changes.

Shiogama sees a fairly even distribution of precipitation throughout the year, though there are distinct wetter and drier periods. The highest amount of rainfall occurs in the summer and early autumn months. July and August are the wettest, with a total of 6 mm of precipitation each and the highest number of rainy days—18 and 20 days respectively. This indicates that rain occurs frequently in the summer, though it is not necessarily heavy given the total volume.

September and October are also characterized by relatively high precipitation (5 mm), with 16 and 13 rainy days respectively. Winter months, such as January, February, November, and December, are the driest in terms of total precipitation volume (just 2 mm each). However, even in these months, precipitation occurs quite often: January and December see 14 wet days each, February has 9, and November has 10.

Given the low average and minimum temperatures in the winter months (for example, in January the average is 1.5°C and the minimum is -1.5°C), precipitation during this period likely falls as snow or sleet, especially from December to February. Spring months (March, April, May) show a gradual increase in precipitation from 3 mm to 4 mm, with the number of wet days ranging from 11 to 12. There is no clearly defined dry season in Shiogama where precipitation is virtually absent; rather, there is a transition between periods of more frequent and slightly heavier precipitation (summer to early autumn) and periods with lower volume but still regular precipitation (winter to spring).

When planning a trip to Shiogama, it's important to consider the variable weather and frequent precipitation throughout the year. The key packing principle should be layering. Regardless of the season, you'll need comfortable walking shoes, as there is plenty to see in the city and its surroundings. Also, don't forget an umbrella or a light raincoat—even if the forecast predicts low precipitation, the number of rainy days can be significant, especially from June to September.

In winter (December to February), it is quite cold in Shiogama, with average temperatures hovering around 1-3°C and nights potentially dropping below freezing. Therefore, warm clothing—a jacket, sweater, hat, gloves, and scarf—is essential. Spring (March-May) and autumn (October-November) are characterized by gradual temperature changes: from cool in March and November (average temperature 6-10°C) to moderately warm in May and October (15-16°C). A mid-season jacket, a fleece, and several layers of light clothing are ideal for these periods to adapt to the changing conditions. Summer (June-August) is the warmest time of year, with average temperatures between 20-25°C. Light, breathable clothing, sunscreen, and a hat are recommended. However, given that summer has the highest number of rainy days, a light waterproof jacket or umbrella will still be useful.
