Bermuda Weather Service Forecast Discussion
For Saturday, June 13, 2026
09:00 UTC
FORECASTER - Lawrence Doughty
NOWCAST: (Today and tonight)
High pressure centered to the distant SE remains the dominant feature
as occasionally thick cirrus continues to stream into the area from
the north. A moderate WSW値y breeze becomes increasingly humid, allowing
near-average temperatures to develop over the holiday weekend. Isolated
showers, visible on radar imagery remain distant but models suggest
the chance of a brief sprinkle, especially when coupled with local
effects and/or daytime heating. Despite occasionally cloudy spells,
mostly fine and dry weather is expected into Sunday as upper ridging
helps to sustain anticyclonic flow at the surface. Moderate WSW値y
winds persist into Sunday. Slight to moderate seas persist.
WATCHES, WARNINGS and ADVISORIES: None.
AVIATION: VFR conditions are expected to persist throughout the
period. RWY 30 is expected to remain active with winds 220-270 9-17
knots increasing slightly towards the end of the period. For more

SHORT TERM FORECAST: Sunday through Monday
A robust Omega-block in the northern Atlantic creates a somewhat
stagnant synoptic pattern through the short term as the Bermuda-Azores
High holds firm to maintain a moderate WSW値y breeze, maintaining
mostly dry conditions throughout, although weak surface troughing
may send the odd sprinkle into our area, particularly early and late.
Model QPFs remain trace, with layer cloud thickening at times on
Sunday, before dissipating to allow extensive sunshine on Monday.
Moderate WSW値y winds ease slightly into Monday, before backing SW値y
during National Heroes Day. Increasing humidity allows local temperatures
to increase with Monday progged to be the hottest day of 2026 so
far with a high near 28ーC/82ーF. Slight to moderate seas remain throughout.
WATCHES, WARNINGS and ADVISORIES: None anticipated.
LONG TERM FORECAST: Tuesday through Wednesday
Persistent anticyclonic flow aloft allows the BDA-Azores High to
remain in place over the central Atlantic through the long term.
A meandering frontal boundary to the north causes a pressure gradient
squeeze, maintaining moderate SW値y winds as seen in the latest marine
charts. The chance of sporadic shower activity increases slightly
as weak convergence/troughing presses in, although model QPFs remain
trace with only the GFS suggesting 1-2mm痴. Therefore, a blended
forecast approach has been maintained. Winds are currently expected
to remain moderate and back SSW値y on Wednesday, although the UK
currently suggests marginally strong winds may develop at times on
Wednesday. Slight to moderate seas remain throughout.
WATCHES, WARNINGS and ADVISORIES: None currently expected. Slight
chance of a SCW for marginally strong winds on Wednesday.
