Typhoon activity in Guam is strongest from July to October, when most typhoons in the north-west Pacific form and make landfall. The Japan Meteorological Agency names each typhoon in the basin. A typhoon starts as a cluster of thunderstorms over warm ocean water. Warm, moist air rises from the sea surface. The air pressure near the surface drops, and more air flows in. The rotation of the Earth makes this air spin, anticlockwise in the Northern Hemisphere. Weak winds high in the atmosphere let the system organise. A system with a closed circulation is called a tropical depression. It becomes a tropical storm when its winds strengthen, and the Japan Meteorological Agency gives it a name. It becomes a typhoon when its winds reach typhoon strength. Sea temperatures around Guam are highest in late summer. This is the time of the most storm activity. Typhoons often form over the warm water of the western Pacific Ocean. Typhoons often pass close to Guam on the way west towards the Philippines and Japan. ## Past typhoons in Guam Storms that affect Guam can come from the north-west Pacific Ocean.

The typhoon tracker map on this RainViewer page shows current storm tracks near Guam, and the list under the map names each active storm near Guam. When no storm is active, the list says so and links to storms in other regions. Past storms near Guam are listed further down the page. ### When is typhoon season in Guam, and which months are busiest? Typhoon activity in Guam is strongest from July to October, when most typhoons in the north-west Pacific form and make landfall, and the Japan Meteorological Agency names each typhoon. The Japan Meteorological Agency is the regional warning centre for the basin. Typhoons often pass close to Guam on the way west towards the Philippines and Japan. ### Which official source issues typhoon warnings for Guam? The National Weather Service office in Guam publishes the official weather warnings for Guam, and the Japan Meteorological Agency (JMA) publishes forecasts and advisories for every active storm in the north-west Pacific basin. RainViewer shows storm tracks on a map and does not replace official warnings. The JMA is the source for official basin forecasts. ### What does the forecast cone show on the Guam map? The forecast cone on the RainViewer map shows the probable track of the centre of a storm during the forecast period. The cone does not show how far wind, rain, or storm surge reach from the centre, so areas outside the cone can still have storm effects. The cone is part of the Storm Tracks layer, together with the current position, the past path, and the forecast path. ### Where can I see rain radar for Guam? RainViewer shows rain radar for Guam, and the [Guam weather radar page](https://www.rainviewer.com/radars/guam.html) lists radar coverage and links to city radar pages.
