Only free day this week is a drizzly one — how bad is inspecting in light rain, really?

Galway, second year, two hives, and the west of Ireland is doing its thing: forecast is drizzle every day I'm off work for the next week. I'm due an inspection — it's been 9 days, strong colony, swarm season not fully over — and my only realistic window is tomorrow in what Met Éireann optimistically calls 'patchy light rain'. Everything I read says don't open hives in rain: all the foragers are home so they're crankier, you chill the brood, flying weather matters, etc. But what's the actual damage if it's 15C, barely misting, and I keep it under ten minutes? Is a fast damp inspection worse than stretching to 14+ days during swarm season? Genuine question about the lesser evil here, not looking for permission to be lazy — the opposite really.
