What a normal is

A climate normal is the average of a weather element over a 30-year reference period. Normals describe what is typical — they are not a forecast, and an individual month can depart from them substantially without being unusual in any meaningful sense.

Normals are the baseline against which the monthly climate summary reports whether a month was wetter, drier, warmer or cooler than usual.

Normals vary across the island

The figures above are for Point Salines on the dry southern coast. The interior highlands around Grand Etang receive several times that rainfall, and Carriacou and Petite Martinique are drier than mainland Grenada.

Using a single station's normals for the whole tri-island state will mislead — particularly for rainfall.
