Many of these
place names are spelled wrong, or are incomplete.
Many of them are listed as being in
a country which doesn't exist any more.
This is how they appear on the source data, in most cases.
There isn't the time to fix them right now (I have to go and do real
work!), but they should be better in the next version (might be quite a
Do you have any data for ...?
The only places currently online are those you can
find by searching.
Try looking for a nearby place, and also
try spelling the placename in the local language.
Remember: enter a place name (city, town) only. Don't enter a region such
Tuscany or a country name. If in doubt of the spelling, just enter the
first few characters.
Can you add the data for ...?
Most of this data comes from large data sets with hundreds and
thousands of places in them, and I'm adding more all the time.
So if it is missing now, it MIGHT appear later
from a new source. Otherwise,
the best bet is to search for nearby placenames.
Was it raining in New York on 15 August 1994?
I don't have any practical way to look up specific data for
a given time period or date. This site concentrates on long term
averages. You might find some recent date-specific data at
NCDC (mostly US data, much of it
Also, for the US only there's daily data since 1994 at
Will it rain tomorrow in Chicago?
This is not a weather forecasting (or reporting) site.
I don't know what the weather will be like anywhere tomorrow (or
yesterday). The climate averages will help you determine the
normal weather, but that's no guarantee it will be normal when you get
Is this data accurate?
NO. All climate data has errors, it is certain that
some are present here. This data has been distilled (both by
the data sources and by me) from
several billion individual readings made by tens of thousands of
people in every part of the world over the past couple of centuries.
It has then been transcribed, summarized, modified and converted by
many more people in many countries.
This is unlikely to be a perfect
Please read the disclaimer. Having said
all that, every attempt has been made to keep it as accurate as
possible, please let me know if you find any major numeric errors.

Are you going to have sunshine data?
Yes, for some places, as soon as I can get the data processed,
formatted, documented and uploaded. The same goes for snowfall,
humidity, wind, and so on. They're all in queue and will be dealt with
as time permits, but as I'm working full time on several other jobs this
will be a while!
What does Average Temperature mean?
To see definitions of terms such as Average Temperature, Rainfall etc,
What is the average climate for the USA, Netherlands, etc
Climate figures for a large area are meaningless. For example, an average
for the USA would include Alaska and Florida. This would give a nice mild
climate that is unlike most parts of the US and be quite useless. Most
climates you see published that give the climate for a "country" are in
fact the climate of the capital city, or a major city.
Some northern Pakistan climate data is out by six months (seasons
reversed). Rainfall for Paris Montsouris, and Larnaca, is 2.54 times too
(inches/centimeters confusion!). These are errors that were in the source
will be corrected in the next version. There are also a few cases where
an annual total is very slightly different from the sum of the months,
caused by rounding and conversion errors, again this is something that I'm
looking at closely in the next version.
Please email your comments, suggestions for improvements, bug reports
misspelled place names or countries!), and complaints by using the

back specific information for a place as I'm too busy working on the next
version of this site.
