Atlas Risk Score · 22nd safest of 220
3 of 7 pillars estimated from neighbouring countries — global datasets don't cover Guam separately.
Where the risk actually is
Risk is rarely spread evenly across a country. The base colour is the code the Dutch Ministry of Foreign Affairs gives Guam as a whole; shaded regions are those the UK Foreign Office names in an advisory against travel.
What the warnings actually cover
-
Whole country — No specific warning. No government currently advises against travel to any part of this country. The colour reflects general caution levels only, not a warned area.
Shading marks whole regions named in an advisory, but a warning is often narrower — a border strip, one road, or a single city. Read the wording, and check the official advisory linked below.
What drives the score
Each pillar is scored 0–100 against every other country. Longer bar = more risk.
Biggest factor here: natural hazards. Earthquakes, floods, cyclones, drought and tsunami exposure.
Practical facts
The things worth knowing before you land.
When to go
Average daytime high and nightly low for Hagåtña (the middle of the country — there is no capital in the dataset), over 2010-2019. Bars are rainfall; the colour band is how hot the days get.
Mildest and driest around November to June.

- World Bank Open Data — governance, homicide, road deaths, health and economic indicators
- INFORM Risk Index 2026 (European Commission JRC) — natural hazard, epidemic and conflict exposure, coping capacity
- UK Foreign, Commonwealth & Development Office — travel advice and regional warnings
- Netherlands Ministry of Foreign Affairs — colour-coded travel advice, including region-level zones
- US Department of State — travel advisory levels 1-4
