Weather Text Generator

Search for a place name, paste GPS coordinates, use My Location, or click the map. A valid coordinate pair moves the map to that point. Any other text is searched as a place name. An invalid pair, such as a latitude above 90, shows an error in the search results.

Enter latitude first, then longitude. These forms are accepted:

• Decimal: 45.832, 6.865
• Hemispheres: 45.832 N, 6.865 E or N45.832 E6.865
• Degrees, minutes, and seconds: 45°49'55"N, 6°51'54"E
• Labels: lat: 45.832, lon: 6.865
• A geo: link, or a Google, Apple, or OpenStreetMap link that already contains the coordinates

A comma separates the two numbers, so a European decimal comma such as 45,832 is not read as one coordinate.

After you select a location, the tool asks Open-Meteo for two compressed messages.

The 12-hour technical window shows conditions about every three hours, including temperature, wind gust, freezing level, precipitation, and visibility when they matter.

The 1–5 day planning outlook gives each day's weather, minimum and maximum temperature, precipitation chance, UV index, and snow-depth change when it applies.

Both are written for a satellite message of about 160 characters. Copy the one you need and paste it into Garmin, Zoleo, or Iridium. Check the text before you send it. This is a planning aid, and it is not an official forecast.

Each message starts with the location, then a block for 0h, 3h, 6h, 9h, and 12h.

LOC:32.49N,77.44E;0h:SN,-18C(0F),G32,FL3800m,P1,SN1,VIS800;3h:OVC,-17C(1F),G35,FL3900m

• LOC:32.49N,77.44E is the latitude and longitude.
• 0h:SN,-18C(0F) is snow at 0 hours, −18°C (0°F).
• G32 is a wind gust of 32 km/h.
• FL3800m is a freezing level of 3,800 metres.
• P1 is precipitation of 1 mm.
• SN1 is 1 cm of snowfall. This is separate from SN used as the snow weather code.
• VIS800 is visibility of 800 metres.
• Later blocks, such as 3h:OVC,…, repeat the same pattern for that hour.

The daily message starts with the coordinates, then one block for each day from D1 to D5.

32.49N,77.44E;D1:OVC,-18/-12C,P40,UV3,S+5;D2:SCT,-20/-10C,P10,UV6

• 32.49N,77.44E is the latitude and longitude.
• D1:OVC,-18/-12C is day 1, overcast, with a minimum of −18°C and a maximum of −12°C.
• P40 is a 40% chance of precipitation.
• UV3 is a UV index of 3.
• S+5 is a snow-depth increase of 5 cm. A minus value is a decrease.
• D2 to D5 use the same pattern.

SN is used in two ways. On its own it means snow. Followed by a number on the 12-hour line, such as SN1, it means snowfall in centimetres. On the daily line, S is the change in snow depth.
