Windsor features a temperate maritime climate, typical of most of the United Kingdom. This means there are no sharp temperature fluctuations: summers are usually warm and pleasant, while winters are mild without severe frosts. The weather can be quite changeable, so it is always worth being prepared for a few surprises when planning your visit.

The city has four distinct seasons. Summer, spanning from June to August, is the warmest time of year. Average temperatures during these months range from 16-18°C, with daily highs reaching a comfortable 20-22°C. Winter, from December to February, is fairly mild here, with average temperatures around 4-6°C. Spring (March-May) and autumn (September-November) are transitional seasons with a pleasant chill and gradual temperature changes. A defining feature of Windsor's climate is the even distribution of precipitation throughout the year. Although total rainfall is low (averaging 2-3 mm per month), there are quite a few rainy days (from 10 to 16 days a month), so a light raincoat or umbrella will be useful companions at any time of year.

The temperature regime in Windsor is characterized by moderate figures throughout the year, typical of the UK climate. The warmest month is usually July, when the average temperature is a comfortable 18.0°C, and daily highs can reach 22.2°C. This is closely followed by August, with an average temperature of 17.6°C and maximums up to 21.6°C. The coolest period is January, when the average temperature drops to 4.8°C, and nightly lows can reach 2.2°C. Overall, the annual temperature trend in Windsor is smooth, without sharp jumps or extreme values.

Summer months in Windsor—June, July, and August—offer pleasant warmth, ideal for walking and exploring the city. Average daily temperatures during this period range from 20.4°C in June to 22.2°C in July. Nights also remain relatively warm, with minimum temperatures ranging from 11.6°C in June to 13.8°C in July. This creates comfortable conditions for evening activities and outdoor relaxation, though it is always worth having a light jacket on hand for the evening chill or sudden rain.

The winter season in Windsor, covering December, January, and February, is notably mild. Average monthly temperatures during this period range from 4.8°C in January to 6.2°C in December. Night frosts do occur, but severe cold is not characteristic: minimum temperatures usually range from 2.2°C to 3.9°C. During the day, the thermometer most often shows between 7.5°C and 9.1°C. Diurnal temperature fluctuations in Windsor are moderate: the difference between daily highs and nightly lows averages from 4.6°C in December to 8.9°C in May, providing relatively stable temperature conditions throughout the day.

Precipitation in Windsor is characterized by a fairly even distribution throughout the year, with no pronounced rainy season or prolonged dry period. Total monthly precipitation is consistently low: most months receive around 2 mm, with only October standing out slightly with 3 mm. This indicates that heavy downpours are not typical for this area.

Despite the low total amount, rainy days in Windsor occur regularly. The highest frequency of precipitation is observed in March, with an average of 16 rainy days. October and December are also quite damp in terms of rainy days, with about 14 days each. The fewest rainy days occur in June—an average of 10 days—making it the month with the highest probability of dry weather.

Given that a small amount of rain is spread over a significant number of days, it can be concluded that Windsor is characterized primarily by light, drizzling rain or short-lived showers rather than prolonged downpours. Winter temperatures generally remain above freezing, so significant snowfall is rare; winter precipitation most often falls as rain or occasionally sleet, which usually melts quickly.

When packing for Windsor, keep in mind the changeable British weather. The key to a comfortable trip in any season is layering. A light T-shirt, a jumper or fleece, and a windproof, waterproof jacket will allow you to easily adapt to temperature changes and sudden rain. Given that light drizzle occurs quite often (10-16 days per month), even with a low total volume (2-3 mm), a compact umbrella or raincoat will be your faithful companions. Don't forget comfortable shoes for long walks around the city and its surroundings, as there is plenty to see in Windsor.

During the summer months (June-August), when average temperatures hover around 16-18°C and highs can reach 20-22°C, you will need lighter clothing, but don't forget to pack a sweater or light jacket for the evening chill or windy weather. Sunscreen and a hat will also come in handy. In winter (December-February), average temperatures stay around 4-6°C, so you'll need warm clothing: sweaters, an insulated and preferably waterproof jacket, a hat, scarf, and gloves. In spring and autumn, the weather can be especially unpredictable, so the principle of layering is most relevant—be prepared for both sunny days and cool, rainy spells.
