🌡️
Temperature, side by side
Average daytime highs and overnight lows for all 12 months, plus each city’s hottest and coldest month.
🌧️
Rainfall totals
How much rain falls each month and across the year, so you can see monsoons, dry seasons and wet winters.
💧
Humidity & wind
Average relative humidity and wind speed month by month — the difference between 30°C dry and 30°C sticky.
☀️
Solar radiation
Average kWh/m²/day for each city, useful for solar planning, gardening and agriculture.
📅
Any single year
Switch from the long-term average to any individual year back to 1981 to see how that year actually went.
🧭
Best time to visit
A plain-language verdict on which city is warmer, wetter and most comfortable, and when to go.
✈️
Planning a trip
Two destinations, one holiday window. See which is drier and more comfortable in the month you can actually travel, rather than in the month the brochure was photographed.
📦
Moving or relocating
What a move really changes day to day: how much colder the winters get, how much wetter the year is, and whether the humidity will make the same temperature feel different.
🎓
Choosing a university or job city
Four years or a two-year posting is long enough for climate to matter. Compare the months you would actually be there, not the annual average.
🌇
Retiring somewhere milder
Mild has two halves — summers that are not punishing and winters that are not harsh. The monthly table shows both, so a warm annual average cannot hide a brutal July.
🔆
Solar and energy planning
Average solar radiation in kWh/m²/day for both locations, month by month — the number panel yield estimates are built on.

Gardening and agriculture
Growing seasons, rainfall timing and humidity side by side, to see whether what thrives in one place has a chance in the other.
The first line is the verdict: which city is warmer by day, which has warmer nights, and which gets more rain — with the gap stated in both °C and °F. It is the answer most people come for, and it is deliberately the first thing on the page.
Day and night are separate questions. Two cities can share an annual average while one swings twenty degrees between afternoon and dawn and the other barely moves. Coastal cities hold their heat overnight; high and dry ones give it back. The monthly table splits highs from lows so that difference is visible rather than averaged away.
Annual rainfall hides its timing. Two cities can receive the same millimetres a year and feel nothing alike — one in a three-month monsoon, the other spread evenly. The rainfall chart shows when it actually falls, which is what determines whether a trip is washed out.
Humidity decides how the temperature feels. 30°C dry and 30°C sticky are the same number and a different experience, which is why the comfort verdict weighs humidity alongside temperature rather than ranking on heat alone.

Where does the climate data come from?▼
Every figure comes from NASA POWER (Prediction Of Worldwide Energy Resources), built on MERRA-2 satellite and model data. We hold monthly records for each city from 1981 onwards, so most comparisons are based on more than four decades of observations.
Is this forecast data?▼
No. This tool compares long-term climate — what the weather is typically like in each city at a given time of year. It is designed for planning trips, relocations and outdoor projects rather than telling you whether it will rain next Tuesday.
Can I compare cities in different countries?▼
Yes. Any two places can be compared, whether they are in the same state or on opposite sides of the world. Temperatures can be shown in Celsius or Fahrenheit, and rainfall in millimetres or inches.
How many cities can I compare?▼
About 235,000 cities and towns worldwide — every populated place with a recorded population, not just capitals and big cities. If a town appears in the search box, it can be compared. Somewhere we have not read before takes a few seconds the first time while its climate record is retrieved, then it is instant for everyone afterwards.
Which city is hotter?▼
The comparison answers this in its first line: it names which city is warmer by day, which has warmer nights, and by how much, in both Celsius and Fahrenheit. Underneath, a month-by-month table shows how often each city is the warmer of the two across the year — two cities can have the same annual average and still feel nothing alike.
Which city gets more rain?▼
The same summary line gives the annual rainfall difference in millimetres and inches, and the monthly chart shows when that rain actually falls. A city with a short, intense monsoon and a city with steady drizzle all year can receive identical annual totals.
What is the best time to visit each city?▼
Each comparison ends with the most comfortable months for both cities, worked out from temperature and humidity together rather than temperature alone. It is the quickest way to find a window that suits both halves of a trip.
Is it free, and do I need an account?▼
It is free and there is no sign-up. The comparison is worked out in your browser from our climate records, so nothing you pick is stored against you.
Can I switch between Celsius and Fahrenheit?▼
Yes — the °C / °F switch above the results converts every figure, and your choice is remembered as you move around the site.
How many years of data does each comparison use?▼
Records begin in 1981, so most comparisons rest on more than four decades of monthly observations. That is long enough for the averages to be stable rather than reflecting one unusual year.
Why do two nearby towns sometimes show identical numbers?▼
NASA POWER reports on a grid rather than per settlement, so two places within roughly 50 km can fall inside the same grid cell and share a reading. If both columns look identical, the cities are simply too close together for the data to tell them apart.
Can I share a comparison?▼
Yes — once you pick two cities the page address updates, so copying the link from your browser and sending it to someone will open the same comparison for them.
