GIS – 30 April, 2020: The Winter 2020-Seasonal Outlook provided by the
Mauritius Meteorological Services (MMS), which gives an insight of the expected
evolution of the climate during the winter months in Mauritius and Rodrigues,
indicates that the onset of winter will be earlier and will settle down as
from the end of April 2020.
The period from May to October has been defined as the
winter season in Mauritius and Rodrigues. The Wintry type weather has been
observed as from the second week of April. Based on both linear regression
models and probabilistic climate forecast from various climate models, the most
likely outcome for winter 2020 is as follows:
· Rainfall over Mauritius is likely to be
near normal during the first half of the season and slightly below normal for
the second half. The cumulative rainfall is expected to be around 600 mm and it
will be concentrated mainly over the Central Plateau, to the East and the
· Normal rainfall is expected over Rodrigues
with a mean of 400 mm over the island.
· Day maximum temperature will be close to
the normal during first half of winter and slightly above normal during the
second half in both Mauritius and Rodrigues. Night temperature is expected to
be slightly above normal.
However, the MMS highlights that there will be
intra-seasonal variation, when on certain occasions the Mascarenes will be
under the influence of strong anticyclones. In these instances, both Mauritius
and Rodrigues are likely to experience relatively cooler surge resulting in
below normal temperature.
On a few rare occasions, especially due to clear sky
and calm wind condition, the minimum temperature in Mauritius may likely drop
to near 10 degrees Celsius. In Rodrigues, minimum temperature may drop to near
13 degrees Celsius over the high grounds.
