You can find the weather forecast for around 17,000 localities in Finland on the local weather webpage. You can also check the weather at foreign locations on our local weather page.
The Finnish Meteorological Institute's web service contains dozens of different weather products. This page give you more detailed information on the updating schedules and production methods of these services. Please note that the Institute cannot guarantee that information is always updated at the times given.
You can find the weather forecast for around 17,000 localities in Finland on the local weather webpage. In addition to all of Finland's municipalities, the list also includes villages, districts and islands. You can also check the weather at foreign locations.
The weather forecast is given for the place selected in the Local weather quick menu. Using text prediction, you only need to give the first letters of the place name and then pick the interesting weather forecast on the list of suggestions. The place names are from the GeoNames database, which is updated by the users.
Weather symbols, temperatures and wind speed and direction depict the forecast situation at a given time.
The local weather forecast applies to inland weather. Marine weather forecasts can be found in the Marine weather and Baltic Sea section.
The weather forecast is not dependent on the nearest weather observation station. For example, if you select Kotka from the local weather menu, you will see a forecast for the centre of Kotka rather than a forecast for the off-shore Kotka Rankki observation station. This is despite the fact that the nearest observation station to Kotka is situated at sea.
Forecasts are updated several times every day.
See the explanations for the weather symbols used for the web service.
A forecast spanning several days is often more uncertain than the forecast for the next day. In the ten-day forecast, temperature and precipitation quantities are also depicted using a probability forecast produced by the weather forecast model. In coastal and other marine areas in particular, the weather forecast generated by the weather model may deviate significantly from the weather forecast given by the meteorologist. This also applies when temperatures has large day and night variation. This is especially so at the beginning of a forecast.
The temperature scale is on the left-hand side of the graph and the precipitation scale is on the right. Temperatures are measured in whole degrees and precipitation to an accuracy of one tenth.
Temperatures are depicted with red bands.
Precipitation is depicted using blue bars.
The temperature given is the value at a given time. The precipitation quantity is the precipitation accumulated during the past six hours, given in millimetres.
The probability forecast is updated twice every twenty-four hours. The update time may vary due to production-related factors.
The probability forecast is given by the European Centre for Medium-Range Weather Forecasts (ECMWF).
Weather forecasts presented using weather symbols are given by a meteorologist. These forecasts do not always fall within the probability range.
The meteorologist's temperature forecast is marked on the graph using a black dotted line. The meteorologist's forecast may sometimes deviate significantly from the probability forecast calculated by the computer model.
The meteorologist updates the weather forecast to cover a period of just under 10 days. The end of the graph may show a brief period wherein only the weather model's probability forecast is shown.
You can find weather forecasts and sunrise and sunset times for thousands of foreign locations on our local weather page.
Using text prediction, you only need to give the first letters of the place name and then pick the weather forecast interest you on the list of suggestions. The place names are from the GeoNames database, which is updated by the users. If you find any errors in the names, please notify GeoNames using the feedback form.
Local time is used in forecasts, for example 3, 9, 15 and 21.
Observations are not in international weather.
Precipitation probability forecasts are only available for the following areas adjacent to Finland:
Ten-day forecasts are available for a slightly wider area. In Western Europe the boundary lies north of the 51st parallel, while in Eastern Europe it is slightly further to the south. In Russia the area extends east of the area for which precipitation probability forecasts are available.
Local weather observations are collected from the Finnish Meteorological Institute's observation stations. The name of the observation station is given together with the observations. Information is updated generally every 10 minutes.
The page shows one or more observation stations closest to the forecast site. All localities do not necessarily have a suitable observation station within the same municipality. Some localities have several observation stations.
Observations are not in international weather.
The observation stations transmit the following data, depending on the station:
The observation quantities reported vary from station to station depending on what data are measured at each station. There is only one daily precipitation observation from precipitation stations.
Cloudiness codes are converted to text as follows:
Observation curves are updated as frequently as the observation data in text format. The observation quantities reported vary from station to station depending on what data are measured at each station. There is only one daily observation from some stations (daily weather).
Local weather shows the weather radar observations (precipitation data) from the last hour as an animation updated at 5-minute intervals. Similarly, it shows data on lightnings from the flash observation system. The image is updated every 5 minutes. You can change the time in the image step by step by rolling the scroll wheel of your mouse.
The sunrise and sunset times given are the values calculated for the locality in question. If there are any minor differences between these times and other sources determining sunrise and sunset times, they may stem from the fact that sunrise and sunset times are calculated using several astronomical formulas. Moreover, the coordinate points used in the calculation may give rise to differences in the times given.
