Weather in Every Country, by Month and by Day: A Traveller's Planning Guide

Weather is the single variable that shapes a trip more than any other. It decides whether a beach week is worth the airfare, whether a mountain pass is open, whether a city break means outdoor terraces or queuing indoors in the rain. Flights and hotels can be rebooked. A monsoon cannot.

That is why more travellers now start their planning with climate data rather than deals. The quickest way to do that is to check the weather in any country by month and by day before you commit to dates, so you are choosing your travel window around real conditions rather than guesswork.

Once the timing is right, the rest follows: trip1.com gives access to more than 3 million hotels worldwide, so once you know which month suits your destination, finding the right place to stay in it is straightforward.

The harder part, and the part worth doing first, is understanding what the weather actually does in a given country at a given time of year. This guide breaks that down region by region, then by month.

Why Monthly Averages and Daily Forecasts Are Two Different Tools

Travellers often confuse two kinds of weather information, and the confusion costs money.

Climate averages by month describe what a place normally does. They are built from decades of records and answer questions like "how hot is Marrakech in August" or "does it rain in Bali in October". These are planning numbers. They are what you use three months out, when you are choosing dates, booking flights and deciding whether to pack hiking boots or swimwear.

Daily forecasts describe what a place will actually do over the next one to two weeks. They answer questions like "will it rain on Thursday". These are packing and itinerary numbers. They are what you use in the final days before departure and while you are on the ground, reshuffling a museum day and a beach day.

Both matter, and they are best consulted in sequence. The trip1 travel weather guide by month and day covers both, letting you look up conditions by country, by city, by month and by individual day. Checking the monthly picture first, then narrowing to the daily forecast closer to travel, is the workflow that avoids most weather-related disappointments.

Europe

Europe's compact size hides real climate variety, from subarctic Lapland to near-desert conditions in southern Spain.

Southern Europe (Spain, Portugal, Italy, Greece, Croatia, Malta, Cyprus, Turkey) runs on a Mediterranean pattern: hot dry summers, mild wet winters. July and August bring 30 to 40°C inland and peak crowds. May, June, September and early October are the sweet spot, with warm sea temperatures and manageable heat. Winter is quiet and often wet, though the Canary Islands and southern Cyprus stay mild enough for beach weather year round.

Western Europe (France, UK, Ireland, Netherlands, Belgium, Germany) is temperate and changeable. Rain is possible in any month, so the question is temperature rather than precipitation. June to September is reliably pleasant, with 20 to 28°C. April, May and October are cooler and less crowded. Ireland and western Britain are the wettest parts of the region; the German and French interiors see colder winters than the coasts.

Northern Europe (Norway, Sweden, Finland, Denmark, Iceland, Baltic states) has a short, bright summer and a long dark winter. June to August offers long daylight hours, temperatures of 15 to 25°C and the best conditions for hiking and fjords. December to March is aurora and winter sports season, with heavy snow inland and milder, wetter weather on the Norwegian and Icelandic coasts. Iceland is windy in every month and its weather changes hour to hour, which makes daily forecasts essential there.

Central and Eastern Europe (Poland, Czechia, Hungary, Austria, Switzerland, Romania, Balkans) has a continental climate: warm to hot summers, genuinely cold winters. May to September is the main travel window. Alpine areas add a second season from December to March for skiing, with reliable snow above roughly 1,500 metres.

Asia

Asia contains almost every climate type on the planet, and monsoon timing is the key thing to get right.

Southeast Asia (Thailand, Vietnam, Indonesia, Malaysia, Philippines, Cambodia, Laos, Singapore) is tropical and hot all year, with the wet season doing the real work of shaping travel. Broadly, November to April is the dry season for Thailand, Cambodia, Laos and southern Vietnam, while May to October brings heavy rain. Indonesia and Malaysia have monsoon cycles that vary by coast: Bali is driest from May to September, while the east coast of Peninsular Malaysia is wettest from November to February. Vietnam is long enough to have three separate climates at once, so check by city rather than by country. Typhoon risk in the Philippines and central Vietnam peaks from July to November.

East Asia (Japan, South Korea, China, Taiwan, Hong Kong) has four distinct seasons across most of its populated areas. Spring, late March to May, brings cherry blossom and mild temperatures. Autumn, late September to November, is generally the most reliable season, dry and clear. Summer is hot and humid, with a rainy season in Japan in June and July and typhoon risk from July to October. Northern China, Korea and Hokkaido have cold, snowy winters; southern China and Taiwan stay mild.

South Asia (India, Nepal, Sri Lanka, Maldives, Bhutan) is dominated by the southwest monsoon from June to September. October to March is the main travel season for most of India, with pleasant days and cool nights in the north and warm weather in the south. April and May are extremely hot across the interior, regularly above 40°C. Nepal's trekking seasons are October to November and March to April, when skies are clearest. Sri Lanka has two monsoons on opposite coasts, so there is always a dry side: the west and south are best from December to March, the east from May to September. The Maldives is driest from December to April.

Central Asia and the Caucasus (Kazakhstan, Uzbekistan, Kyrgyzstan, Georgia, Armenia, Azerbaijan) has hot dry summers and cold winters. April to June and September to October are the most comfortable months, avoiding both the 40°C summer peaks of the Uzbek desert cities and the deep winter cold of the steppe.

Middle East (UAE, Saudi Arabia, Qatar, Oman, Jordan, Israel, Egypt) is best from November to March, when daytime temperatures sit between 20 and 28°C. Summer in the Gulf is severe, often above 45°C with high humidity on the coast. Jordan and Israel have mild wet winters, with occasional snow in the highlands.

Africa

North Africa (Morocco, Tunisia, Algeria, Egypt, Libya) follows a Mediterranean pattern on the coast and desert conditions inland. March to May and September to November are ideal. Coastal cities stay mild in winter; Saharan areas swing from very hot days to cold nights.

West Africa (Senegal, Ghana, Nigeria, Ivory Coast, Gambia) has a wet season that generally runs from May or June to October, with a drier, dustier period from November to March when the Harmattan wind blows south from the Sahara. November to February is the most comfortable travel window.

East Africa (Kenya, Tanzania, Uganda, Rwanda, Ethiopia) has two rainy seasons in much of the region: long rains from March to May and short rains in November. The dry months, June to October and January to February, are prime safari season, when wildlife concentrates around water. Altitude matters more than latitude here: Nairobi and Addis Ababa are cool year round despite sitting near the equator.

Southern Africa (South Africa, Namibia, Botswana, Zimbabwe, Zambia, Mozambique) has reversed seasons. May to September is dry winter, the best time for game viewing and comfortable daytime temperatures. October to April is the wet summer, greener and hotter, with afternoon thunderstorms. Cape Town is the exception, with a Mediterranean climate that makes November to March its warmest, driest stretch.

Indian Ocean islands (Mauritius, Seychelles, Madagascar, Zanzibar) are warm all year. Cyclone season runs roughly from November to April, and the driest, coolest months are May to October.

The Americas

United States and Canada span too many climates for a single answer. The Northeast and Midwest have cold snowy winters and warm humid summers, with autumn foliage peaking in October. Florida and the Gulf Coast are pleasant from November to April and humid with hurricane risk from June to November. The Southwest, including Arizona and Nevada, is best from March to May and October to November, with summer highs above 40°C. The Pacific Northwest is wet from October to April and reliably dry from July to September. California divides into a mild coast and a hot interior. Canada's main travel season is June to September, with a winter sports season from December to March.

Mexico, Central America and the Caribbean have a dry season from roughly December to April and a wet season from May to November. Atlantic hurricane season officially runs from June to November, peaking in September. The southern Caribbean, including Aruba, Curacao and Trinidad, sits largely outside the main hurricane belt. Highland cities such as Mexico City and Guatemala City stay temperate year round.

South America covers both hemispheres. Brazil, Argentina, Chile and Uruguay have southern-hemisphere seasons, so December to March is summer: ideal for Patagonia and the southern coasts, hot and humid in Rio and the Brazilian interior. June to August is winter, which suits Andean skiing and the Atacama Desert. Peru and Bolivia are best from May to September, the dry season for Machu Picchu, the Sacred Valley and the Uyuni salt flats. The Amazon basin is wet year round, with higher water from December to May and easier walking from June to November. Colombia and Ecuador, sitting on the equator, vary by altitude rather than season.

Oceania

Australia reverses the northern calendar. December to February is summer, best for Tasmania, Melbourne and the southern coasts, and uncomfortably hot in the Red Centre and the tropical north. The northern regions, including Darwin and Cairns, have a wet season from November to April with high humidity and cyclone risk, and a dry season from May to October that is the best time to visit. The Great Barrier Reef is most reliable from June to October.

New Zealand has mild, changeable weather. December to February brings the warmest conditions and longest days. June to August is ski season in the Southern Alps. The South Island west coast is one of the wettest inhabited places on earth, so rain gear is not optional.

Pacific islands (Fiji, French Polynesia, Samoa, Vanuatu) are warm year round, with a drier season from May to October and a wetter cyclone season from November to April.

Practical Points Worth Remembering

Altitude beats latitude. Quito sits on the equator and is cool all year. Cusco is tropical on paper and cold at night. Always check the elevation of the specific city, not just the country.

Shoulder seasons are usually the best value. The month either side of peak season often delivers similar weather with lower prices and fewer people. Late September in Greece and early May in Italy are good examples.

Sea temperature and air temperature diverge. The Mediterranean is warmest in late August and September, several weeks after the air temperature peaks. A May trip to Greece can be warm on land and cold in the water.

Humidity and wind change how temperature feels. Thirty degrees in Dubai in July is not the same as 30°C in Madrid in July. Check humidity figures alongside the headline temperature.

Rainfall totals hide the pattern. Tropical destinations often record high monthly rainfall that falls in short, heavy afternoon bursts, leaving most of the day usable. Temperate destinations can record less rain spread across many grey days. The total alone will mislead you.

Putting It Together

The most efficient way to plan is to work from broad to narrow. Start with the monthly climate picture to choose your destination and dates. Confirm the pattern for the specific city rather than the country, particularly in large or mountainous places. Then, in the final fortnight, switch to daily forecasts to finalise your packing and decide which days to spend outdoors.

You can check weather abroad by month, by day and by city in one place, which covers both stages of that process, and with more than 3 million hotels worldwide available through trip1, booking around the weather rather than in spite of it becomes the default rather than the exception. Get the timing right and everything else about a trip gets easier.
