The climate in Qazvin is characterized as continental with semi-desert features, meaning distinct seasons with significant temperature fluctuations throughout the year. Winters are quite cold, with average temperatures hovering around freezing (January averages -0.0°C) and low precipitation.

Spring (March–May) and autumn (October–November) in Qazvin are transitional seasons with milder temperatures. Spring sees a gradual warming, with average temperatures rising from 6.9°C in March to 16.4°C in May; this is also the period with the highest—though still modest—amount of precipitation (2-3 mm per month) and rainy days. Autumn brings a pleasant coolness after the summer heat, and light precipitation is also possible. For tourists, this means that the timing of a trip will largely depend on preference: summer is ideal for lovers of hot and sunny weather, while spring and autumn offer milder conditions for walking and exploring the city, albeit with some chance of rain, particularly in the spring.

For example, in July, the difference between the nighttime low (17.3°C) and the daytime high (31.1°C) is nearly 14 degrees.

Qazvin has a distinct precipitation pattern throughout the year, with a clear divide between dry and wetter periods. The city experiences a long and very dry summer season from June to September. During this time, precipitation is practically zero (0 mm), and the number of days with any precipitation is minimal, especially in August, which averages only one such day.

The wetter period occurs during the autumn, winter, and spring months, roughly from October to May. The highest, though still moderate, amount of precipitation falls in the spring: February, March, and April each record 3 mm monthly. In winter, particularly in January when the average air temperature is around -0.0°C and the minimum can drop to -4.3°C, precipitation most likely falls as snow. Snow is also possible in December and February when nighttime temperatures drop below freezing. In other months with precipitation (March, April, May, October, November), it is predominantly rain.

In terms of the wettest months, February, March, and April lead in total precipitation. March stands out for the frequency of precipitation, with an average of 14 rainy days. This is followed by May (12 days), and February and April (11 days each). Conversely, the summer months from June to September are the driest, when rain or any other form of precipitation is a rarity, making summer in Qazvin sunny and dry.

When planning a trip to Qazvin, it is important to consider the significant seasonal temperature fluctuations and potential wind. In summer (June–August), it is hot and dry, with average temperatures reaching 22-24°C and maximums exceeding 30°C. During this period, you will need light, breathable clothing made from natural fabrics, a hat, sunglasses, and sunscreen. Since there is almost no rain in summer, an umbrella is unlikely to be needed. However, even in the hot months, evenings can be cooler, so a light cardigan or shawl may come in handy.

Winter in Qazvin (December–February) is cold, with average temperatures around 0°C and nighttime frosts. Warm clothing is necessary: sweaters, fleece jackets, an insulated jacket or coat, a hat, gloves, and a scarf. Although precipitation is low (2-3 mm per month), there is a possibility of sleet or rain, so waterproof footwear and outerwear are advisable. Spring (March–May) and autumn (September–November) are transitional seasons with moderate temperatures. In these periods, it is best to use a layering approach: T-shirts, shirts, light sweaters, and a jacket that can be taken off or put on depending on the weather. Keep in mind that it can be windy in Qazvin, especially during transitional seasons or in open spaces. A light windbreaker or other wind-resistant clothing will be very useful. The number of "wet days" is noticeable in spring and autumn, so a compact umbrella or raincoat won't go amiss. Comfortable shoes are recommended for city walks and sightseeing at any time of year.
