About this app

Owing to system upgrade to enhance IT security, the “MyObservatory” will no longer support version 4.16.1 or earlier versions starting from 1 Sep 2022. Users of older versions are urged to update the app as soon as possible to continue using the “MyObservatory” service. User may find the app version by tapping “more options” button at top right corner > About. Users may also visit HKO’s website ( to obtain latest weather information.

The “MyObservatory” is a highly popular weather mobile app providing personalized weather services. The app provides current weather including temperature, relative humidity, rainfall, wind direction and speed, as well as weather photograph collected from nearby weather stations at user's location, specified location, or selected weather stations. Weather photos and rainfall data will be updated at 5-minute and 15-minute intervals respectively. Other data will be updated in 10-minute interval and the update time will be displayed at the bottom of the front page.

Points to note:

1. In the "My Location Settings", users can opt for using the automatic location service provided by the smartphone, or designating "My Location" on the map themselves. This location will be displayed on the main page and in "My Weather Report". If your location cannot be found, "My Location" will show the last location which was successfully found or "Hong Kong Observatory". The meteorological data displayed on "My Location" or the station you added is provided by meteorological stations nearby, and is not necessarily from a station in the same region. In case meteorological data is not available from nearby stations, data from other meteorological stations at headquarter of the Observatory, King's Park, and Star Ferry will be used instead. If this is the case, the symbol ▲ will appear to the left of the updated time.

2. The notification service of the mobile app including weather warnings, Location Specific Heavy Rain Information, Location-based Rain and Lightning Forecast, etc. is provided using the Google Firebase Cloud Messaging (FCM). The Observatory cannot guarantee the successful or timely reception of push notifications via the mobile app. Users should not rely on the mobile app as the only means for reception of important weather information. Depending on factors such as network usage and quality of connection of user's mobile phone, it may take 5 to 20 minutes or even longer for the app to receive the notification after it is issued by the Hong Kong Observatory.

3. Although the “MyObservatory” is a free app, user will be charged by their mobile network service provider on the use of data service. These charges can become very expensive on roaming. Please ensure that the option of “Data Roaming” have been disabled in the settings of your mobile devices.

4. Owing to the difference in topography and altitude between the weather station and user's location, and also the error in the estimated position given by the mobile device, users should note that weather information displayed on the app may be different from actual conditions in using the "MyObservatory".

5. The clock on the main page of the app is synchronized automatically to the Observatory's Internet Time Server, and may not be the same as the time displayed on the smartphone.

6. Use of Location-based Rain and Lightning Forecast notification, and Location-specific Heavy Rain notification will increase the battery usage and data download slightly. Users who wish to save battery usage of the app may enable the notification function in rainy days and before outdoor activities, and disable the function in sunny days and after finishing the outdoor activities.

7. To allow user to get hold to important weather information such as weather warning, Special Weather Tips, location-based rain and lightning forecast, etc., the “MyObservatory” would automatically notify users the above information according to user’s settings.

Not responsive and weather update is not always working. Today, there is a typhoon no.8, yet there was no weather warning and Storm Track reports no storm within the area. Has to restart the app again and again to get weather update. Weather photo is showing 2 months old photos. Since last update of the App, Myobservatory has been unstable and unreliable. Please fix this or lose trust. It is bad enough when weather information is inaccurate, worst when it is due to faulty software.

seems the new version has more bugs after fixing. it takes minutes to load the home page, that every developer knows it is not acceptable. please revert to the previous version.

Don't like the new UI design to see the 'local forecast, '9 day forecast' and 'extended outlook', whereby you have to click in the up arrow or down arrow area to show and hide the above options. It's just not that user friendly, too often I click the Android back button to return to previous screen but end up exiting the app. Swiping to show options is so much better than clicking areas to show info.
