Exterior coatings need a minimum temperature and reasonable humidity to cure properly, and the south coast's mild but damp winters and unpredictable spring weather make timing more than a simple matter of picking a month on a calendar. Getting the window wrong risks a coating that never fully cures.
Most exterior coatings have a minimum application temperature, and this needs to hold not just during application but through the early curing period afterwards. High humidity slows curing regardless of temperature, and coastal mornings often carry damp air well into the day, which pushes a realistic start time later than an inland job.
A mild dry spell in late autumn can offer better conditions than an unsettled week in early summer. Watching the actual short-range forecast, rather than assuming a fixed calendar season, gives a more reliable basis for committing scaffolding and labour to an exterior job.
Where a firm deadline exists, planning the sequence so weather-sensitive coats happen in the most reliable part of the window, with less critical preparation work filling the less certain days either side, keeps a programme moving without forcing paint onto a damp or cold surface.
Only in genuinely settled, mild spells and with a coating rated for the conditions. Continuous exterior programmes through deep winter are generally not realistic on this coastline.
Not always. Coastal dew and mist often need to burn off first, so a slightly later start can actually give a more reliable surface to work on than an early one.
Materials and labour can usually be turned around quickly once a settled spell is forecast, but scaffolding lead times are the main constraint worth planning around in advance.

Exterior decorating windows on this coast are set by actual humidity and temperature conditions, not by which month it happens to be.
