I think I actually prefer going to the London Wetland Centre in the rain on summer weekends.
It's a guaranteed cheerful-banker whatever the weather but it's usually packed with young families enjoying picnics on sunny Sundays.
On Sunday I felt like I was the only person there. It rained steadily all afternoon - from the minute I left the house for the 15-minute cycle ride until the minute I got back looking like one of the Water Vole specialities - but all that did was keep the crowds away and dampen the noise of the Heathrow jets overhead.
Empty hides meant I could faff about trying and failing to get a decent photo of one of the dozens of F1-quick Swifts without disturbing anyone.
Then a soggy amble to the opposite end of the reserve gave me a chance for a solo sit to watch and snap the Sand Martins flying to and from their nests in the purpose-built sandbank: Sand Martins raising their young across the river from Craven Cottage - fantashtic, as Fulham's new Dutch manager Martin Jol might say.
The main downside of the rain was the lack of decent insects on the wing. The place is usually teeming with dragonflies and butterflies when the sun's out in June.
But there's always next weekend.
