0-1 0-1 Calm Sea like a mirror.
Calm; smoke rises vertically.
1-3 1-3 Light Air Ripples with the appearance of scales are formed, but without foam crests.
Direction of wind shown by smoke drift, but not by wind vanes.
4-7 4-6 Light Breez Small wavelets, still short, but more pronounced. Crests have a glassy appearance and do not break.
Wind felt on face; leaves rustle; ordinary vanes moved by wind.
8-12 7-10 Gentle Breeze Large wavelets. Crests begin to break. Foam of glassy appearance.
Perhaps scattered white horses.
Leaves and small twigs in constant motion; wind extends light flag.
13-18 11-16 ModerateBreeze Small waves, becoming larger; fairly frequent white horses.
Raises dust and loose paper; small branches are moved.
19-24 17-21 Fresh Breeze Moderate waves, taking a more pronounced long form; many white horses are formed.
Small trees in leaf begin to sway; crested wavelets form on inland waters.
25-31 22-27 Strong Breeze Large waves begin to form; the white foam crests are more extensive everywhere.
Large branches in motion; whistling heard in telegraph wires; umbrellas used with difficulty.
32-38 28-33 Near Gale Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind.
Whole trees in motion; inconvenience felt when walking against the wind.
39-46 34-40 Gale Moderately high waves of greater length; edges of crests begin to break into spindrift. The foam is blown in well-marked streaks along the direction of the wind.
Breaks twigs off trees; generally impedes progress.
47-54 41-47 Severe Gale High waves. Dense streaks of foam along the direction of the wind. Crests of waves begin to topple, tumble and roll over. Spray may affect visibility.
Slight structural damage occurs (chimney-pots and slates removed)
55-63 48-55 Storm Very high waves with long overhanging crests. The resulting foam, in great patches, is blown in dense white streaks along the direction of the wind. On the whole the surface of the sea takes on a white appearance. The tumbling of the sea becomes heavy and shock-like. Visibility affected.
Seldom experienced inland; trees uprooted; considerable structural damage occurs.
64-72 56-63 Violent Storm Exceptionally high waves (small and medium-size ships might be for a time lost to view behind the waves). The sea is completely covered with long white patches of foam lying along the direction of the wind. Everywhere the edges of the wave crests are blown into froth. Visibility affected.
72+ 64+ Tropical Cyclone Very rarely experienced; accompanied by wide-spread damage.

Papua New Guinea National Weather Service (PNGNWS) is a government institution and is the sole mandatory body in Papua New Guinea responsible for providing meteorological and climate information to the Government and people of Papua New Guinea.
PNGNWS is a member of World Meteorological Organization (WMO), thus, our functions and services strictly follow WMO standards and requirements.

We aim to scientifically improve public safety and awareness in relation to weather and climate events (past, present and future) by ensuring that our weather/climate products are disseminated on 24/7 daily basis to the general public, aviation industry, marine industry, agriculture sector, responsible authorities and other specific entities.
Subsequently, we believe that our services may implicitly (or explicitly) contribute in impacting economic and social activities within Papua New Guinea and the region.
We have a nation-wide network of weather and climate observation stations operating as either manual or automatic. Our head office is locate in Port Moresby, 7 mile, Skidrow Street, near Jacksons International Airport.
