Month-by-Month Guide
January
January is typically the coldest month in Hannover, with grey skies and that damp cold that seems to seep through your clothes. You'll likely see some snow, though it tends to be more slushy than picturesque, and daylight hours are quite short. The city feels quieter after the holiday rush, with locals bundled up and hurrying between warm cafes.
February
February is marginally warmer than January but still firmly in winter's grip, with occasional sunny days that give false hope of spring. The humidity combined with cold temperatures creates that bone-chilling dampness that's characteristic of northern European winters. Carnival season brings some festive energy to the city, though it's not as elaborate as in western German cities.
March
March is when you start seeing the first real signs of spring, with temperatures gradually climbing and daylight hours noticeably lengthening. That said, the weather can be quite unpredictable - you might get a beautiful sunny day followed by sleet the next. The city's parks start showing green shoots, and locals emerge from hibernation to enjoy the occasional warm afternoon.
April
April truly brings spring to Hannover, with cherry blossoms in the Herrenhäuser Gardens and tulips popping up throughout the city. The weather is famously changeable though - the German saying "April, April, der macht was er will" (April does what it wants) exists for a reason. You'll want layers, as mornings can be chilly while afternoons might be warm enough for just a light jacket.
May
May is genuinely lovely in Hannover, with everything in full bloom and temperatures that are comfortable for exploring without overheating. The city's numerous parks and gardens are at their best, and outdoor beer gardens start filling up. You might still get the occasional rainy day, but there are enough sunny spells to make this one of the most pleasant months to visit.
June
June marks the beginning of summer with long daylight hours - the sun doesn't set until after 9:30 PM, giving you plenty of time to explore. Temperatures are warm but rarely oppressive, making it ideal for walking tours and outdoor activities. The occasional thunderstorm rolls through, but they tend to be brief and actually provide a nice break from the warmth.
July
July is typically the warmest month, though "warm" in Hannover means pleasantly mild rather than scorching hot. The humidity can make it feel a bit sticky on the hottest days, but it's nothing compared to more southern climates. This is peak season for outdoor festivals and events, with locals making the most of the summer weather while it lasts.
August
August continues the summer warmth with temperatures similar to July, though you might notice the days starting to shorten slightly. The weather can be a bit unpredictable, with some years bringing lovely sunshine and others feeling disappointingly grey and rainy. The Maschsee lake becomes a focal point for locals and visitors alike, with people swimming, sailing, and lounging on the shores.
September
September is often underrated but can be absolutely beautiful, with warm days, cooler evenings, and the leaves just starting to turn. The tourist crowds thin out as schools go back in session, but the weather is often still pleasant enough for outdoor activities. You'll want to start packing a warmer jacket for evenings, as temperatures can drop quite noticeably after sunset.
October
October brings proper autumn to Hannover, with golden leaves in the city's forests and a crisp edge to the air. The weather becomes increasingly grey and drizzly as the month progresses, though you'll still get the occasional sunny day that makes you want to be outside. This is when locals start seriously layering and the city takes on a more subdued, cozy atmosphere.
November
November is arguably the greyest, dampest month in Hannover - the kind of weather that makes you understand why Germans are so enthusiastic about their Christmas markets. The trees are bare, daylight hours are short, and that persistent drizzle combined with 70% humidity creates a thoroughly miserable outdoor experience. That said, it's a great time for museums and cozy cafes.
December
December transforms Hannover with its famous Christmas markets, which bring warmth and light to the dark winter days. The weather is cold and often grey, with occasional snow that rarely sticks around for long. Daylight is limited - the sun sets before 4 PM - but the festive atmosphere and twinkling lights make it feel cozy rather than depressing, at least until the markets close after Christmas.
