Stay informed about weather conditions in the city of Brunswick before starting your journey. Below are current forecasts and charts to help you prepare for your trip and plan your day wisely.

The climate in Brunswick can be characterised as humid subtropical, ensuring the city enjoys fairly mild weather throughout the year. Its proximity to the ocean moderates temperature fluctuations, so there are no severe frosts here, and summers are typically long and warm. This makes the region comfortable for travellers in almost any season.

Summer months are distinguished by heat and high humidity: average temperatures hover around 26-27°C, and during the day the air often warms up to 30-31°C. The rainy season lasts from June to September: the number of days with precipitation can reach 22 per month. Winter in Brunswick is mild, but nights can be cool. The average temperature during this period is 11-14°C, however, travellers should note that in January and February, the thermometer can drop to 7-9°C.

Many consider spring and mid-autumn the most favourable times to visit. During these periods (especially in April, May, and October), an ideal balance is established: the air warms up to a comfortable 18-23°C, and the likelihood of prolonged rainfall is significantly lower than in summer. This is a wonderful time for walks and exploring the city without exhausting heat.

The temperature pattern in Brunswick is characterised by mildness and the absence of sharp changes, making the climate comfortable for travellers for most of the year. Winter here is very gentle: even in the coldest month, January, the average temperature holds around +10.9°C. Nighttime cooling in the winter period is rarely severe, dropping on average only to +7°C, and during the day the air often warms up to +15°C, allowing you to enjoy walks without heavy winter clothing.

Summer in the city is truly hot and humid. The peak heat falls in July and August, when daytime temperatures regularly reach the +30°C — +31°C mark. In this season, the difference between day and night figures is not too significant: nights remain very warm (about +24°C), which, combined with frequent rains (up to 22 days with precipitation in August), creates a tropical sauna effect. Travellers should be prepared for sultry weather in the middle of summer.

The shoulder seasons in Brunswick are a time of pleasant warmth. Spring arrives rapidly: already in April, the average temperature is about +18.7°C, and May feels like full-blown summer with maximums up to +27°C. Autumn comes gently and retains warmth for a long time: September and October delight with comfortable figures from +21°C to +25°C, offering ideal conditions for tourism without summer heat or winter chill.

Precipitation in Brunswick is distributed unevenly throughout the year, creating two quite distinct periods. The driest and most comfortable season for long walks lasts from mid-autumn to mid-spring. From October to April, the number of days with precipitation stays at a minimal level — on average from 8 to 10 days per month. At this time, rains are typically short-lived and do not create serious obstacles for travellers.

With the arrival of summer, the picture changes, and the city enters a distinct rainy season. Starting from June through September, the frequency of precipitation increases sharply. The wettest months are July and August, when more than 20 rainy days per month are recorded. Given the high summer temperatures reaching 30°C, precipitation often falls in the form of warm downpours, which can bring welcome freshness.

Regarding the winter period, snow for this region of the USA is an extremely rare and uncharacteristic phenomenon. Even in the coldest months, such as January and December, the air temperature remains sufficiently high (on average above +7°C even at night), so rains prevail here in winter. This makes the climate mild and allows tourists not to worry about severe snowfalls.

Summer in Brunswick is hot and humid, so for a trip in the period from June to September, choose light clothing made from natural breathable fabrics such as cotton or linen. Be sure to take headwear, sunglasses, and high SPF cream with you, as the sun here is very active. Considering that in summer the number of rainy days reaches a maximum (up to 22 days in August), a light raincoat or a compact umbrella will become your indispensable companions.

Winter and the transitional seasons in this region are quite mild, but the weather can be changeable. If you are planning a trip from November to March, when the average temperature fluctuates around 10–16°C, the best solution is to dress in layers. Take jeans, long-sleeve T-shirts, jumpers, and a light jacket or windbreaker for cool evenings and mornings. Heavy winter clothing and down jackets are unlikely to be needed here.

Regardless of the season, pack comfortable walking shoes in your suitcase, for example, proven trainers, as you will likely want to walk a lot. It is also worth remembering that even in warm spring months, such as April and May, short-term precipitation is possible, so waterproof shoes or a spare pair will be useful.
