Carolyn, is it really a normal pattern. The rainfall can vary tremendously for the same month from year to year. One or even 2 months might be extra high and the rest closer to average. Some years you'll an extremely high month with others fairly high. But it all happens in the wet season, October to April. Although the wettest is usually December to April.
The rains have eased again so the lilies aren't getting battered now and are making the most of it. They should have another 6 or so weeks and then the water will probably start to drop. Where they are there wouldn't be water by June. Then no water until December or maybe even January.
