Yes, but that's my point. Where I'm currently living (UK, south coast) it's 15C at 77% RH outside, so to get below 50% RH inside the temperature needs to be at least 22C (which it isn't). It's not uncommon for the humidity to get up to 80-90% RH when it rains, and the temperature doesn't drop much.
When it gets to the cold part of winter it's obviously easier, but this time of year it's hard to get it below 50% RH inside just by controlling the temperature.
