The stretch of coast from Chichester round to Poole gets weather that changes by the hour rather than the day, with showers rolling in off the Solent between longer dry spells. A workable exterior programme here is built around short windows rather than assuming a whole week will run clean.
Sea breezes push moisture-laden air onshore and can produce a shower on the seafront while streets half a mile inland stay dry. We watch short-range coastal forecasts rather than a general regional one, because the two can disagree by several hours on a given day.
Rather than committing a whole crew to one elevation for a full day, we often keep two or three tasks live so a sudden shower means moving to sheltered work rather than standing the job down entirely.
A shower an hour after a masonry coat has gone on can wash pigment and binder straight off an uncured film, which is far more costly than losing an hour to weather in the first place. Knowing how long a specific product needs before it can tolerate rain is as important as knowing the forecast.
On larger elevations we sometimes split coats between calmer and more exposed days rather than trying to do a whole wall in one sitting, so a change in weather part-way through does not leave a visible join between old and new conditions.
We use short-range coastal forecasts alongside what we can see on site, since seafront conditions can differ from those a short distance inland. Local knowledge of how weather moves along this coast matters as much as the app.
It depends how long the coating has had to set. Some products tolerate light rain within an hour, others need most of a day. We check the specific product's rain-fastness time before starting a coat if the forecast looks marginal.
It can add time rather than cost directly, since a job may need more calendar days to catch enough dry windows. We build that into the programme honestly rather than under-promising the finish date.

Coastal weather changes fast, so a workable exterior programme plans for short windows rather than long dry runs.
