Atlas Risk Score · 92nd safest of 220
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 Tonga as a whole; shaded regions are those the UK Foreign Office names in an advisory against travel.
This map reads milder than the world map's colour, and both are right. The world map shades Tonga by its Atlas Risk Score — 25, Low — which blends government advice with crime, health, roads and natural hazards. This map shows the advice alone, and the strongest level anywhere in Tonga is no specific warning.
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: road & transport. Road deaths per 100,000 people - the risk travellers most underestimate.

Mildest and driest around May to December.
