Germany is a Central European country, 357,022 km² with population of 84 million — the EU's most populous country. The country is bordered by Denmark (north), Poland and the Czech Republic (east), Austria and Switzerland (south), and France, Luxembourg, Belgium, and the Netherlands (west). Germany has 16 federal states (Bundesländer), each with distinct culture and dialect. The famous "Fall of the Berlin Wall" on November 9, 1989 and the subsequent 1990 reunification of West Germany and East Germany (formally the Federal Republic of Germany and German Democratic Republic) ended 45 years of Cold War division. Germany is the world's 4th-largest economy and a major industrial power. The country has been a federal parliamentary republic since 1949.
Major destinations include Berlin (the famous capital — population 3.7 million, with the famous Brandenburg Gate, the famous Reichstag with Norman Foster's glass dome, the famous Berlin Wall Memorial and East Side Gallery, the famous Holocaust Memorial, the famous Museum Island UNESCO World Heritage, Checkpoint Charlie, the famous Tiergarten park, and extensive Berghain-led nightlife culture), Munich (the famous Bavarian capital — population 1.5 million with the famous Marienplatz town hall with its Glockenspiel, the famous Hofbräuhaus beer hall, the famous Englischer Garten — one of the world's largest urban parks, the famous Residenz palace, and host of the famous Oktoberfest at Theresienwiese), the famous Neuschwanstein Castle (the famous "Disney castle" built by King Ludwig II in the 1860s, inspiring Walt Disney's Sleeping Beauty Castle), the famous Bavarian Alps (with Garmisch-Partenkirchen, Berchtesgaden, and Zugspitze — Germany's highest peak at 2,962 m), the famous Romantic Road (the famous 350 km scenic route through Bavaria with Rothenburg ob der Tauber — Germany's best-preserved medieval town, Würzburg, Augsburg), the famous Black Forest (the famous southwestern forest with cuckoo clocks, Baden-Baden spa town, and the famous Triberg waterfalls), the famous Rhine River with extensive medieval castles along the Middle Rhine UNESCO World Heritage, the famous Mosel Valley wine region, Hamburg (the famous port city with extensive maritime culture and the famous Speicherstadt UNESCO World Heritage), Cologne (with the famous Cologne Cathedral UNESCO World Heritage), Dresden (the famous "Florence on the Elbe" rebuilt after WWII bombing with the famous Frauenkirche, Zwinger Palace, and Semperoper opera house), Heidelberg (the famous romantic university town with castle ruins), Frankfurt (the famous financial capital), the famous Christmas markets (Nuremberg, Dresden, Munich, Cologne, Aachen — all world-class), and the famous Bauhaus Sites (Weimar, Dessau, Bernau — UNESCO World Heritage).
Germany has the most clearly defined four seasons of any major European country. Spring and autumn are dramatic; summer is warm but not extreme; winter is genuinely cold and atmospheric. The country's famous festivals — Oktoberfest, Christmas markets, Karneval — happen on specific weeks that drive both atmosphere and prices.
Quick verdict
Best overall: Late May through July and September. Long days, pleasant temperatures, beer gardens open.
Best for the Christmas markets: Late November through mid-December. Nuremberg, Munich, Cologne, Dresden are world-class.
Best for Oktoberfest: Late September through early October. Book accommodation 6+ months ahead.
Best for budget travelers: January-February and November (excluding Christmas markets in late November).
Avoid if you can: Munich during Oktoberfest unless you want the event itself (prices triple, city is mobbed). January-February in the Bavarian Alps for non-skiers (cold, short daylight).
Spring (March to May): the country emerges
March is variable. Berlin averages 4-9 °C with frequent rain and occasional snow. The first cherry blossoms appear in late March in the Rhineland and south. Famous garden cities (Heidelberg, Mainau) start their displays. Outside major events, this is one of the country's quietest tourist months.
April brings warmer weather and Easter. Bavaria, Bavaria, and the Black Forest see Easter tourism. The famous spargel (white asparagus) season begins in late April — German restaurants put on elaborate asparagus menus through June. Tulip displays in major cities peak.
May is widely considered the second-best month for Germany. Long days, comfortable temperatures (15-22 °C), beer gardens open in earnest from mid-May. The Romantic Road (Rothenburg, Würzburg, Augsburg) is at its most photogenic. Wine regions of the Rhine and Mosel are green and active. The famous Maibaum (maypole) traditions in Bavaria bring local color.
Summer (June to August): festival and beer garden season
June is excellent. Daytime 18-25 °C, long daylight, beer gardens in full operation. The longest day of the year brings outdoor concerts and Sankt Hans festivities. Berlin's nightlife scene operates at peak. The Bavarian Alps have their best hiking weather of the year — daytime 18-23 °C, snow gone from most trails, mountain refuges fully open.
July is the warmest month. Daytime 21-27 °C nationally, with occasional heat waves pushing past 32 °C. German summer holidays start in some Bundesländer in July (others in August). Tourist crowds peak in the Bavarian Alps, the Romantic Road, and Berlin. The famous Wagner Festival in Bayreuth runs through late July and August.
August continues full summer. Many smaller restaurants close for two-week holidays. Berlin pulses with electronic music festivals and outdoor culture. The Rhine river cruises operate at peak schedules. The famous summer thunderstorms can be dramatic but typically clear quickly.
Autumn (September to November): Oktoberfest and harvest
September is excellent. Daytime 15-21 °C, harvest underway in the wine regions, comfortable weather for the Black Forest, Bavarian Alps, and Romantic Road. Crowds drop sharply after the first week as school holidays end.
Oktoberfest in Munich runs from late September through the first weekend of October. The Theresienwiese fills with the world's most famous beer festival — 14 enormous tents, traditional Bavarian dress, brass bands, and roughly six million visitors over 16 days. Munich hotel rates triple during the festival. Book accommodation 6-9 months ahead if attending. The first weekend (opening) and the final weekend are most crowded.
October is one of the most photogenic months for Germany. The Black Forest turns autumn colors. Vineyards in the Mosel and Rhine show dramatic gold-and-red foliage. Berlin's parks are golden. Daytime cools to 10-17 °C. The wine harvest culminates in October, bringing harvest festivals to almost every German wine village.
November is shoulder. Days shorten dramatically — by month's end, sunset is at 4:30 pm. Weather is wet and gray. The Christmas markets begin opening in late November (most start the last week, some on November 27-28 specifically). Hotel prices reach annual lows in early-to-mid November before market prices spike late month.
Winter (December to February): Christmas markets and ski culture
December brings the Christmas markets. Nuremberg's Christkindlesmarkt is the most famous; Dresden's Striezelmarkt is the oldest (1434). Cologne, Munich (Marienplatz), Aachen, and Frankfurt all have spectacular markets. Markets typically run from late November (some November 27-28) through December 23. Hot Glühwein, roasted nuts, hand-carved nativities, and elaborate light displays define the season. Hotel rates spike during market weeks; book 3-4 months ahead.
Christmas Day itself (December 25-26) sees nearly everything closed across Germany. The week between Christmas and New Year is quieter than the markets; tourist crowds are domestic. January 6 (Epiphany) is a holiday in Bavaria and Baden-Württemberg.
January and February are deep winter. Berlin averages 0-5 °C with occasional snow. The Bavarian Alps and Black Forest get serious snow — Garmisch-Partenkirchen, Oberstdorf, and other ski resorts operate from mid-December through March. Outside skiing, this is one of the quietest tourist periods.
February brings Karneval/Fasching, particularly in Cologne, Düsseldorf, and Mainz. The "crazy days" (Weiberfastnacht through Rosenmontag, six days before Ash Wednesday) bring elaborate costumes, parades, and revelry. Cologne's Rose Monday parade is one of Germany's biggest events.

Verdict by traveler type

Christmas markets focused: First three weeks of December. Strasbourg/Colmar over the French border are excellent additions.

Bottom line
Germany delivers excellent travel experiences from May through October, with two world-class festival windows (Oktoberfest and Christmas markets) that justify visits at other times. The country is well-organized for tourism year-round; even winter visits work if you accept short daylight and the trade-off of significantly lower prices.
